REGULATORY IMPACT ANALYSIS STATEMENT
(This statement is not part of the Regulations.)
1. Executive summary
Issue: Greenhouse gases (GHGs) contribute to climate change and the most significant source of anthropogenic GHG emissions is the combustion of fossil fuels. The emissions of GHGs have been increasing significantly since the industrial revolution and this trend is likely to continue if no action is taken.
In December 2009, the Government of Canada committed to a national greenhouse gas reduction target of 17% below 2005 levels by 2020, and inscribed this in the Copenhagen Accord. The 2020 target is aligned with that of Canada’s largest trading partner, the United States (U.S.).
To achieve its target, the Government of Canada has established a comprehensive plan to reduce GHG emissions in all major emitting sectors, on a sector-by-sector basis. In moving forward with this plan, the Government of Canada published the proposed Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations on August 27, 2011 (Canada Gazette, Part Ⅰ [CGI], Vol. 145, No. 35).
In 2010, the latest year of emissions data available under Canada’s National Inventory Report (NIR) under the United Nations Framework Convention on Climate Change (UNFCCC), total GHG emissions were about 6% (48 megatonnes [Mt]) below 2005 levels.
In the same year, GHG emissions from the electricity generation sector represented around 15% (101 Mt) of Canada’s total emissions. (see footnote 8) Coal-fired electricity generation, which represents only 15% of total electricity generation, was responsible for 77 Mt of GHG emissions in Canada, about 77% of total electricity sector emissions.
These Regulations addressing coal-fired electricity generation are a key part of meeting the Government of Canada’s 2020 commitments under the Copenhagen Accord and ensuring that investments in new electricity generation infrastructure support long-term GHG emission reduction goals.
Description: The Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations (the Regulations) will set a stringent performance standard for new coal-fired electricity generation units and those that have reached the end of their useful life. The level of the performance standard will be fixed at 420 tonnes of carbon dioxide per gigawatt hour (CO2/GWh). This approach will implement a permanent shift to lower- or non-emitting types of generation, such as high-efficiency natural gas, renewable energy, or fossil fuel-fired power with carbon capture and storage (CCS).
The performance standard of the Regulations will come into effect on July 1, 2015. Regulated entities will be subject to enforcement and compliance requirements and penalties as specified under the Canadian EnvironmentalProtection Act, 1999 (CEPA 1999).
The Government’s approach to addressing climate change is based on the principle of maximizing environmental performance improvements while minimizing adverse economic impacts. The electricity industry is facing major capital stock turnover. A number of electricity generation facilities are reaching the end of their useful lives, and regulatory uncertainty would impede investments in new generation capacity. These Regulations provide industry with the certainty needed to make the necessary investments to continue to meet the growing need for electricity generation given projected economic growth, while at the same time delivering significant reductions in GHG emissions by regulating the phase-in of lower-emitting sources of generation.
The Regulations are designed to minimize stranded capital by targeting the point of capital stock turnover. For example, in the absence of regulations now, industry may build new standard coal-fired units to replace those due to retire in the coming years, and as a result would face much higher costs to reduce GHG emissions under potential, future regulations.
Consultation: Since publication of the Regulations in CGI, the Government has received a significant number of comments and has undertaken extensive consultations on both the details of the Regulations and the economic analysis. Overall, support was expressed for the proposed regulated performance standard but concerns were raised regarding the impact on specific units, or alignment with existing provincial regulatory programs. Among the non-governmental organizations (NGOs) consulted, some had questions regarding the regulatory approach in terms of the impact on GHG emission reductions. As well, significant changes to the underlying economic analysis were made as a result of productive consultations with provinces. This Regulatory Impact Analysis Statement (RIAS) outlines the final regulatory provisions, the updated cost-benefit analysis (CBA) that is a result of these consultations, and the Government’s responses to major comments received.
Cost-benefit statement: The Regulations are estimated to result in a net reduction of approximately 214 Mt CO2e of GHG emissions over the period 2015–2035. The Regulations result in significant climate change and air quality benefits; the present value of the benefits in 2015 is estimated at $23.3 billion, due in part to the avoided costs of climate change of $5.6 billion, avoided generation costs of $7.2 billion, and health benefits of $4.2 billion from reduced smog exposure associated with reduced risk of death, avoided emergency room visits and hospitalization for respiratory or cardiovascular problems. The analysis also assumes that the Regulations will spur investments in fossil fuel-fired power with carbon capture and storage (CCS) technology. Where the captured CO2 is used for enhanced oil recovery (EOR) an additional net benefit of $4.7 billion is expected as a result of incremental oil production.
The present value of the costs of the Regulations in 2015 is estimated at $16.1 billion, largely due to the increased use of natural gas for fuel ($8.0 billion), reduced net exports of electricity ($0.3 billion), and incremental capital costs ($1.9 billion). The net present value (NPV) of the Regulations in 2015 is estimated at $7.3 billion (i.e. the benefits of the Regulations outweigh the costs by a margin of $7.3 billion). (see footnote 9)
The sensitivity analysis shows that the costs and benefits are sensitive to key variables such as fuel prices and the discount rate. However, under all the sensitivities that were analyzed, the NPV remained positive with the Regulations generating a net benefit. The results of the analysis are expressed in 2010 dollars and are discounted at 3% after 2015, when the Regulations take effect.
Distributional analysis: The largest GHG reductions from the utility sector are expected in Alberta (160 Mt), followed by Saskatchewan (45 Mt) and Nova Scotia (15 Mt). Avoided costs of climate change associated with provincial reductions are as follows: $4.1 billion in Alberta; $1.1 billion in Saskatchewan; and $0.4 billion in Nova Scotia.
The largest improvements in air quality from reduced smog exposure are expected to occur in Alberta and Saskatchewan, providing significant human health benefits to residents of those provinces of $2.7 billion in Alberta, and $0.6 billion in Saskatchewan. The net benefits associated with EOR of $4.7 billion occur completely within Saskatchewan.
The distribution of net cost impacts is similar to the distribution of benefits across provinces. Alberta is expected to incur the largest increase in net generation costs ($5.9 billion), followed by Saskatchewan ($1.2 billion). Minimal impacts are expected in other provinces and territories.
Business and consumer impacts: Electricity prices in Canada are expected to increase in the future with or without the regulatory performance standard due to a shift towards natural gas. The Regulations are expected to have a very limited impact on gross domestic product (GDP), as the effects of slightly higher costs in electricity generation are offset by new oil production through enhanced oil recovery. For individual Canadians, the Regulations generate health and environmental benefits through improved air quality and reduced GHG emissions. The gradual phase-in of the Regulations defers most of the price effects to beyond 2020. This moderates the impact on consumers, and results in the share of household budget spent on electricity remaining relatively constant.
In the residential sector, the average annual change over the analytical period in residential electricity prices as a result of the performance standard is expected to have the greatest impacts in Alberta (1.61 cents per kilowatt hour [kWh]), Saskatchewan (0.74 cents/kWh), and Nova Scotia (0.76 cents/kWh). It is expected that the price increases from the Regulations will be passed on to consumers in proportion to their consumption. Households that consume more (or less) than the average would pay proportionately more (or less) of the total costs.
The Regulations will also have a similar impact on electricity prices in the industrial sector with average annual changes in electricity prices of 1.61 cents/kWh in Alberta, 0.82 cents/kWh in Saskatchewan, and 0.76 cents/kWh in Nova Scotia. These incremental price increases are not expected to have significant impacts on the industrial sector in Canada. In general, Canada has low electricity rates relative to many of its global competitors, and long-term trends continue to show that the sector is using less energy for each unit of economic output.
Domestic and international coordination and cooperation: The Regulations will help move Canada towards the Government’s stated commitment to reduce GHG emissions to 17% below 2005 levels by 2020, which was inscribed in the Copenhagen Accord and is in alignment with the U.S. target. It also produces significant longer-term emissions reductions, supporting global action to reduce GHG emissions. Impacts on international trade agreements are not expected, and within the domestic market, the Regulations reinforce the significant commitments that have already been made by provinces (in particular, Ontario and Nova Scotia) to reduce emissions from coal-fired electricity generation.
Further, the Government of Canada is following an approach to climate change that is broadly aligned with that of the U.S. The U.S. Environmental Protection Agency (EPA) recently released a GHG performance standard that covers new power plants. It also has a permitting process in place for new and modified facilities that can establish even more stringent limits. Finally, while U.S. GHG requirements do not address existing coal-fired electricity plants, the EPA has finalized stringent air pollutant requirements for these plants.
2. Background
The Government has made a commitment, inscribed in the Copenhagen Accord, to reduce domestic greenhouse gas (GHG) emissions by 17% from their 2005 level by 2020. In the 2010 Speech from the Throne, the Government of Canada committed to continuing to take steps to fight climate change by leading the world in clean electricity generation, and reiterated this support for clean energy projects in the 2011 Speech.
The Government of Canada’s approach to addressing climate change is to follow a sector-by-sector regulatory plan to reduce emissions. These Regulations addressing coal-fired electricity generation are a key part of that plan. The Government’s approach is designed to achieve both environmental and economic objectives. Given the highly integrated North American economy, the Government of Canada has followed an approach to address climate change that is broadly aligned with that of the United States.
Environment Canada first announced its intention to reduce GHG emissions in the electricity sector on June 23, 2010. On August 27, 2011, the Government of Canada published proposed Regulations in the Canada Gazette, Part Ⅰ. The proposed regulatory approach applied a stringent performance standard to new coal-fired units and units that have reached the end of their useful life. At the same time it took into account the unique circumstances of individual provinces and specific industry units in order to maintain Canadian competitiveness while achieving real reductions in GHGs.
Publication of the proposed Regulations in CGI initiated a 60-day comment period. Over 5 000 submissions were received during this time, including submissions from 4 provincial governments, 16 electricity industry corporations or system operators, 17 other industry corporations or associations, and 6 NGOs. The remainder of comments came from the general public, primarily through the use of form letters available on various Web sites. Based on these comments and extensive discussions with industry and provinces, certain refinements have been implemented for the Regulations. These refinements provide some greater flexibility to industry, while respecting the CGI regulatory framework and maintaining the contribution of the Regulations to Canada’s Copenhagen target.
3. Issue
Greenhouse gases contribute to climate change and the most significant source of anthropogenic GHG emissions is the combustion of fossil fuels. The emissions of GHGs have been increasing significantly since the industrial revolution and this trend is likely to continue if no action is taken.
Looking to the latest year of emissions data available under Canada’s National Inventory Report under the UNFCCC, Canadian emissions of GHGs in 2010 were about 6% below 2005 levels (48 Mt). In 2010, GHG emissions from the electricity generation sector contributed around 15% (101 Mt) to Canada’s inventory of emissions. Coal-based electricity, which represents 15% of total electricity generation in Canada, was responsible for 77 Mt of GHG emissions, about 77% of total electricity sector emissions.
The electricity industry is facing major capital stock turnover decisions and major new investments are inevitable over the coming years. As of January 2012, there are 45 operating coal units in Canada. However, nearly two thirds of Canada’s coal-fired electricity generation present in 2010 — some 28 coal-fired units — are forecasted to cease operations by 2025. Regulatory certainty with respect to emissions requirements from electricity generation will facilitate investments in new, low- or non-emitting generation facilities at a low incremental cost, and at the same time ensure that investment decisions do not lead to stranded assets in the future. For example, in the absence of regulations now, industry may build new standard coal-fired units to replace those due to retire in the coming years, and as a result would face much higher costs to reduce GHG emissions under potential future regulations.
4. Objectives
The Government’s approach to addressing climate change is based on the principle of maximizing environmental performance improvements while minimizing adverse economic impacts. In 2005, Canada’s total GHG emissions were 740 Mt, representing about 2% of global GHG emissions. The Government of Canada is committed to reducing Canada’s total GHG emissions to 17% below its 2005 levels by 2020, a target that is inscribed in the Copenhagen Accord and aligned with that of the United States. Federal and provincial policies to date and the impact of the coal-fired electricity Regulations will contribute to 25% of the reductions required to meet Canada’s 2020 target.
The Government of Canada is also following an approach to climate change that is broadly aligned with that of the U.S. The U.S. EPA has introduced GHG and air pollutant rules that industry analysts expect will result in the closure of a significant number of their oldest coal-fired units (see section 11 for more details).
To secure the reductions in emissions from electricity generation in support of Canada’s target, the Government is publishing the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations. The objective of the Regulations is to ensure a permanent transition from high-emitting coal-fired electricity generation to low- or non-emitting generation such as renewable energy, high-efficiency natural gas, or thermal power with carbon capture and storage (CCS).
5. Description
5.1 The Regulations
The Regulations, made under CEPA 1999, will apply a performance standard to new coal-fired electricity generation units and to old units that have reached the end of their useful life. The performance standard element of the Regulations will come into effect on July 1, 2015. This ensures that no new high-emitting coal-fired electricity units will be built in Canada.
Under the Regulations, the performance standard is set at the emissions intensity level with consideration of natural gas combined cycle technology — a high-efficiency type of natural gas generation — and will be fixed at 420 tonnes of CO2/GWh. The standard will address emissions of CO2 from the combustion of coal, coal derivatives (e.g. syngas) and petroleum coke (petcoke), and from all fuels burned in conjunction with any of the preceding fuel, except for biomass.
The Regulations address only CO2 because GHG emissions from the electricity sector, including coal-fired electricity generation, are approximately 98% CO2.
The performance standard will be applied to new and old coal-fired electricity generation units. Under the Regulations, new units are those which start producing electricity commercially on or after July 1, 2015. Old units are, in general, those units that have reached 50 years since starting to produce electricity commercially. However, as a transition measure, old units that were commissioned
- before 1975 will reach their end-of-life after 50 years of operation or at the end of 2019, whichever comes earlier; and
- after 1974 but before 1986 will reach their end-of-life after 50 years of operation or at the end of 2029, whichever comes earlier.
Flexibilities will be made available to ensure the integrity of the electricity system, all the while maintaining environmental objectives of emission reductions. These flexibilities are available through application and are subject to ministerial approval. In particular, these flexibilities include the following components:
- New and old units will be able to apply for a temporary deferral until January 1, 2025, from the application of the performance standard if they incorporate technology for CCS. Units that are granted this deferral must meet a number of regulated implementation/construction milestones and submit implementation reports on progress made with respect to these milestones.
- Existing units that employ CCS technology before they are required to meet the performance standard will be able to transfer a two-year deferral from the performance standard to old units in recognition for early action.
- Through the substitution provision, existing units that permanently shut down or meet the performance standard early can transfer a deferral to an old unit.
- An exemption to meeting the performance standard under emergency circumstances will be available where there is a disruption, or a significant risk of disruption, to the electricity supply.
Of the above described elements of these Regulations, the following notable areas were revised based on comments received after the publication of the proposed Regulations in CGI:
- The level of the performance standard was raised from the proposed 375 tonnes of CO2/GWh to 420 tonnes/GWh.
- The definition of useful life was revised to include a phased-in approach based on the unit’s commissioning date, where previously in CGI this definition included consideration of Power Purchase Arrangements (PPAs).
- The regulated milestones for the carbon capture and storage deferral are now the same for both new and old units.
- Existing units that begin capturing before they are required to can transfer an additional six months more than what was proposed in CGI to an old unit in recognition for early action.
- The substitution provision was broadened to recognize existing units that shut down prior to being subject to the performance standard.
In addition, these Regulations no longer require regulatees to report for the two years prior to when the unit would reach their end of useful life and have to meet the performance standard. This amendment significantly reduces the administrative burden of these Regulations, particularly for those units that intend to close prior to when the performance standard would apply to them.
In their entirety, the Regulations are designed to
- Require a stringent performance standard that units must meet, which encourages investment in cleaner forms of electricity generation;
- Provide flexibility in not specifying a technology or fuel that must be used, thus allowing for innovation and technology development, which will drive down costs of implementing the standard;
- Take advantage of existing anticipated capital stock turnover cycles in order to ensure that new investments do not strand existing capital, again helping to minimize costs; and
- Limit costs through a gradual application over time, in line with when units reach their end of useful life and utilities have recovered their initial investment costs.
5.2 Electricity sector
The Regulations focus on coal-fired electricity generation in Canada. To assist in understanding the scope and impacts of the Regulations, the following analysis provides a profile of Canada’s electricity generation sector and the place of coal-fired generation within it. It also examines some of the key features of the sector relating to generation capacity and fuel mix, interprovincial and international electricity flows, and electricity demand, all of which will have a bearing on the assessment of the impacts of the Regulations.
5.2.1 Electricity generators
The Canadian electricity generation industry is composed of utility and non-utility generators that produce electricity by transforming the energy in water, coal, natural gas, refined petroleum products, miscellaneous other fuels, biomass, nuclear, wind and solar resources into energy. The process of supplying electricity to the public involves not only power generation at the plant, but also distribution through the electricity grid.
Overall, electricity generation in 2010 was 542 900 GWh, a decrease of about 2% from the 556 500 GWh observed in 2005. In 2010, hydroelectric power produced 59% of Canada’s total electricity, followed by nuclear (16%), coal (15%), and natural gas (7%), while refined petroleum products (RPPs), other fuels, and other sources such as wind and bioenergy accounted for the remainder (3%).
Internationally, Canada has a relatively low GHG intensity for producing electricity due to approximately 75% of the generation mix coming from non-emitting sources (see Table 1). In comparison, the U.S. has a much higher intensity due to its predominately fossil fuel-oriented system.
5.2.2 Regional trends — Generation and Source
The trends reported below (see footnote 10) are based on utility generators, which represent about 92% of total generation (the remainder are non-utility generators, which do not directly serve the public — they generate electricity for their own end-use or for sale in wholesale markets). Coal-fired electricity generation currently does not represent any of the non-utility combustion-generation mix.
Figure 1 provides a breakdown of electricity generation by region and by source for the years 2005 and 2010. Coal-fired electricity sources are more significant in Alberta and Saskatchewan, due to access to abundant coal resources. Hydro provides the majority of electricity generation in the provinces of Quebec, British Columbia, Manitoba, and Newfoundland and Labrador. In Ontario and the Atlantic region, the electricity generation mix is fairly diverse, with nuclear power providing the greatest percentage of the supply in Ontario. In terms of total generation, Quebec and Ontario have by far the highest generation totals — combined, they produced 316 500 GWh (59%) of Canada’s electricity supply in 2010. They are followed by Alberta (about 57 200 GWh) and British Columbia (about 48 200 GWh), then by Newfoundland and Labrador (40 500 GWh).
Figure 1: Electricity Generation by Region and Source, 2005 and 2010
Overall, national electricity generation has decreased since 2005; however, electricity generation has increased since 2005 in some provinces, such as Saskatchewan (3%) with expanded use of coal and natural gas, and Quebec (5%) with expanded hydro generation, biomass, and other renewables. In Manitoba, a 9% decrease coincided with reductions in coal and hydro generation and increases in other renewable generation, while in Ontario, a 4% decrease in generation coincided with increased nuclear power, and a significant increase in the use of natural gas and other renewable generation. There was also a reduction in generation from coal, refined petroleum products, and hydro. In British Columbia, electricity generated decreased by 11%, which coincided with less hydro generation and less natural gas generation.
5.2.3 Electricity trade flows
Although imports and exports of electricity together represent a very small fraction of total generation, the interconnectedness of the electricity grid with the U.S., combined with varying requirements in different regions of the country, allows the import and export of electricity in response to demand and pricing conditions on both sides of the Canada-U.S. border. As shown in Figure 2, electricity exports to the U.S. grew by 12% between 1989 and 2010, from 22 000 GWh to over 24 000 GWh, respectively. Imports from the U.S. have decreased by about 37% between 1989 and 2010.
On balance, Canada is a net exporter of electricity to the U.S. mainly due to U.S. electricity demand, additional generation capacity, and the availability of low-cost hydroelectric resources. Some regions in Canada, however, rely on imports to meet domestic load requirements during high demand periods (for example during the winter months when electricity use is high in most provinces, and relatively low in many American states) or when water levels are low in hydropower-based provinces.
Figure 2: Imports and Exports with the United States
In recent years, Canadian electricity generation has lagged behind growth in domestic demand. As a result, the surplus available for export has been declining and some regions have increasingly relied on imports to meet domestic requirements during high demand periods. Both Canada and the United States realize commercial benefits and improved electric reliability through trade, mainly due to complementary (off-set) demand peaking seasons.
5.2.4 Actual versus potential generation
Canada’s electricity-generating sector takes advantage of a full mix of hydro, nuclear, wind and other available generating sources. At the same time, actual generation from all these sources is less than potential generation. Potential generation can be determined by assuming capacity is fully operational for each hour, over the entire year. The difference between potential and actual generation can be due to numerous factors including the availability (or lack thereof) of precipitation and wind as well as operational considerations such as required maintenance schedules.
Table 1 shows the actual generation, potential generation and capacity utilization level for major generation types in 2008. Nuclear generation had the highest capacity utilization level in 2008, with actual generation at over 77% of full capacity. This was followed by coal and hydro generation, while other sources such as gas, oil, and wind units had relatively high levels of available spare generation capacity. Typically, coal, gas, and oil units can operate at up to 85% of their potential generation capacity. However, the relatively higher price of gas and oil generation means that it is most often called upon only to meet peak demand, particularly in regions where coal or hydro generation are used to meet base load demand. Over any period of time, actual wind generation is typically much below its full theoretical capacity given the intermittent nature of wind energy.
Table 1: Actual versus Potential Generation — 2008 (see footnote 11)
Type | Actual Generation (GWh) | Potential Generation (GWh) | Capacity Utilization (Actual/Potential) |
---|---|---|---|
Hydro | 373 871 | 652 040 | 57% |
Wind | 3 807 | 20 873 | 18% |
Nuclear | 90 585 | 116 902 | 77% |
Coal | 104 580 | 139 631 | 75% |
Oil | 7 220 | 68 199 | 11% |
Gas | 31 636 | 81 702 | 39% |
Total | 611 699 | 1 079 347 | 57% |
5.2.5 Profile of coal plants/units
Table 2 shows the installed capacity of coal plants/units, by province as of 2010. The Canadian share of coal-fired electricity generation is the largest in Alberta (38%), followed by Ontario (37%), (see footnote 12) Saskatchewan (11%), Nova Scotia (8%), New Brunswick (5%) and Manitoba (1%). Approximately 95% of coal-fired electricity generating units reside in four provinces: Alberta, Ontario, Saskatchewan and Nova Scotia. In 2010, coal contributed to the electricity generation mix in six provinces: Alberta (92% of total generation), Nova Scotia (53%), Saskatchewan (63%), New Brunswick (29%), Ontario (9%) and Manitoba (<1%).
Table 2: Coal Generation Capacity — Year 2010 (see footnote 13)
Region | Number of Coal Plants | Number of Coal Units |
Coal Generating Capacity (MW) |
Share of Total Coal Capacity for Canada |
---|---|---|---|---|
Alberta | 7 | 18 | 6 305 | 38% |
Ontario | 4 | 15 | 6 077 | 37% |
Saskatchewan | 3 | 9 | 1 822 | 11% |
Manitoba | 1 | 1 | 97 | 1% |
Nova Scotia | 4 | 8 | 1 288 | 8% |
New Brunswick | 3 | 3 | 891 | 5% |
Total | 22 | 54 | 16 481 | 100% |
Most of Canada’s coal-fired generation capacity is old and nearing the end of its useful life. As a result, the coal-fired generation sub-sector is expected to undergo a major transition over the next several decades. Environment Canada’s Environment Energy and Economy Model of Canada (E3MC) forecasts that 67% of total coal-fired capacity will cease operations by 2030. More specifically,
- — Between 2010 and 2025, 28 units (51% of total) are expected to cease operations;
- — By 2030, an additional 9 units (67% cumulative); and
- — By 2040, an additional 8 units (82% cumulative). (see footnote 14), (see footnote 15)
Alberta
Alberta’s coal-fired electricity generation fleet is relatively old, with 13 of 18 units present in 2010 expected to cease operations by 2035. Alberta has regulatory requirements for all of the province’s coal units; under the province’s Specified Gas Emitters Regulation, the emissions intensity of existing coal units must be reduced by 12% below the 2003–2005 baseline emissions intensity of the facilities starting in 2007.
Ontario
The Ontario government has enacted regulations requiring that by December 31, 2014, coal no longer be used in their currently operating coal units. Based on these regulations, the remaining generation stations as of 2010 at Atikokan (one unit), Lambton (four units), Nanticoke (eight units) and Thunder Bay (two units) will be closed by 2015. The closure of these coal units is part of Ontario’s commitment to fight climate change. In fact, as a result of Ontario’s decision to phase out coal-fired generation, emissions in Ontario are projected to fall significantly over the 2005–2015 period. Estimates generated by the E3MC range from 22 Mt of CO2 to 33 Mt depending on the timing of retirements.
Saskatchewan
Saskatchewan’s coal-fired capacity is aging, with four out of nine units expected to cease operations by 2035. Through recent consultations, SaskPower has indicated an intention to close two of its coal units in the near term (Boundary Dam units 1 and 2), and the Government of Saskatchewan announced on April 26, 2011, that it has approved the rebuilding of Boundary Dam unit 3 with an integrated CCS system. (see footnote 16) This will be the first commercial-scale fully integrated CCS storage facility in the world. The facility is a demonstration project between industry and the federal and provincial governments to determine the technical, economic, and environmental performance of CCS. (see footnote 17)
Nova Scotia
Nova Scotia has one out of eight units ceasing operations by 2020, and all but two closed by 2030. Nova Scotia’s 2009 Climate Change Action Plan and 2009 Energy Strategy commit the province to undertake orderly transition from dirty coal to cleaner and more sustainable energy sources. Subsequent to these, Nova Scotia’s 2010 Renewable Electricity Plan details the requirement for obtaining 25% of electricity from renewables by 2015, and proposes to increase this to 40% by 2020. Regulations have also been adopted capping the emissions from electricity producers in the province. This will result in reduced use of fossil fuels (primarily coal and petroleum coke [i.e. petcoke]).
The Government of Canada and the Province of Nova Scotia have announced that they are developing an equivalency agreement in an effort to ensure that industry does not face two sets of regulations and to allow the province to achieve equivalent emissions levels as the federal standard in a manner that is appropriate to its particular circumstances.
New Brunswick
New Brunswick had three coal-fired electricity generating units in 2010, two that are expected to cease operations before 2035 and one of which is expected to close by 2039.
Manitoba
Manitoba has only one coal-fired electricity generating unit, which is expected to cease operations in 2030. According to Manitoba’s Climate Change and Emissions Reduction Act, after December 31, 2009, Manitoba Hydro must not use coal to generate power, except to support emergency operations.
Manitoba’s Beyond Kyoto Plan also outlines the introduction of taxes on emissions from coal and provides capital support for coal-reliant industries to convert to cleaner energy and to develop biomass as a coal alternative.
5.2.6 Electricity consumers
Major consumers of electricity are shown in Table 3. The largest consuming sectors are industrial (see footnote 18) (37%), followed by residential (32%) and commercial (26%). Only a small proportion (5%) of electricity is consumed by the public administration, agriculture and transportation sectors.
Table 3: Electricity Consumption in Canada,
1990–2009 (TWh (see footnote 19)) (see footnote 20)
Sector | Sub-sector | 1990 | 1995 | 2000 | 2005 | 2008 | 2009 |
---|---|---|---|---|---|---|---|
Industrial | Iron and steel | 8.3 | 8.3 | 10.3 | 10.7 | 8.7 | 6.5 |
Chemicals | 18.2 | 19.3 | 19.2 | 19.5 | 14.7 | 12.2 | |
Petroleum refining | 5.7 | 4.9 | 5.4 | 6.6 | 6.2 | 5.7 | |
Aluminum and non-ferrous | 37.0 | 47.5 | 50.9 | 59.7 | 52.9 | 51.3 | |
Mining and oil and gas extraction | 28.8 | 31.6 | 33.5 | 37.4 | 32.1 | 28.2 | |
Other manufacturing | 34.2 | 35.3 | 42.3 | 41.1 | 42.6 | 43.0 | |
Pulp, paper and print | 48.8 | 55.9 | 61.6 | 61.7 | 45.3 | 37.2 | |

Industrial sub-sector total | 182.9 | 204.7 | 225.2 | 238.7 | 204.5 | 185.5 | |
Residential | 129.8 | 131.6 | 138.2 | 151.0 | 159.5 | 160.3 | |
Commercial and institutional | 95.6 | 103.6 | 112.1 | 121.0 | 136.9 | 131.7 | |
Others (includes transportation, agriculture, public administration) | 24.6 | 26.6 | 27.8 | 28.5 | 27.3 | 26.0 | |
National total | 432.9 | 466.5 | 503.3 | 539.2 | 528.2 | 503.5 |
Industrial sector
The largest industrial consumers are aluminum and non-ferrous metals, pulp and paper, mining and oil and gas, chemicals, iron and steel and petroleum refining. Other manufacturing is significant but represents a combination of industries.
Since 1990, electricity consumption has increased in two of eight industrial sub-sectors. Among other developments, the shift from a resource-based economy, the rise of the automotive and electronics sector, and the growth of the service/IT industry have all had impacts on industrial electricity consumption. More recently, seven of the eight industrial sub-sectors showed a decrease in electrical consumption relative to 2005 levels, likely a response to economic factors. During this time period, the pulp, paper and print sub-sector showed the largest decrease in electricity consumption while the “other manufacturing” sub-sector (including for example transportation, equipment, electronics, and light consumer goods) showed the largest increase.
Driven by the increase in oil sands production, industrial cogeneration capacity is expected to increase from 5 990 MW in 2010 to 7 322 MW in 2035. Industrial cogeneration capacity is expected to increase at about the same average rate as total national capacity.
Residential sector
The residential sector is a major consumer of electricity, with demand increasing by 24% between 1990 and 2009 (Table 3), largely driven by population growth and rising consumer wealth and living standards. The number of homes in Canada increased by 23% between 1990 and 2009 (the last year for which data are available), and 16% between 2000 and 2009 alone. Growth in residential electricity demand was low to moderate during the recession that occurred in the early 1990s, but consumption increased significantly with higher economic growth after 1999. Fluctuations in seasonal temperatures are an important factor, but a decidedly secondary driver of overall residential electricity demand. Due to improvements in buildings, equipment standards, and energy intensities, single-family and multi-family dwellings are expected to experience an energy intensity improvement of 11% and 13% respectively over the projection period.
Commercial sector
From 1990 to 2009, electricity consumption by the commercial sector has grown by 38% (Table 3), in part due to growth in the service and IT sectors through structural changes in Canada’s economy. This sector has also experienced an increase in the number of commercial buildings and floor space, which has meant larger areas to heat and cool, while computers, printers and other electrical appliances have become commonplace. Growth in electricity demand was particularly strong in more recent years in the commercial sector.
5.2.7 Electricity market structure
Canada’s electricity markets have primarily developed along provincial or regional boundaries, and electricity pricing varies by province or territory according to the volume and type of available generation and whether prices are market-based or regulated. Prices in most provinces and territories are set by an electricity regulator to cover costs and allow for a reasonable rate of return to investors; however, Alberta and Ontario have restructured their electricity markets.
Alberta has moved the furthest in restructuring its electricity market toward market-based pricing (retail customers have the choice of buying electricity at competitive prices from third-party sellers or at regulated prices through the local distribution utility). The price of electricity in the competitive wholesale market is determined by the offer price of the last generation unit required to meet the supply of electricity demanded in the province. System controllers observe all generator offers to the Power Pool and “stack” them from lowest to highest offer price until the supply meets the provincial demand. The majority of coal-fired generators have entered into “purchase power agreements” which establishes, terms up to the year 2020 for the generating station’s output. The owner of the “purchase power agreement” pays the generating station owner a fixed price and then sells the electricity to the retail market at the price determined by the Power Pool.
Ontario partially restructured its electricity market in 2002. Competitive wholesale prices apply to most large consumers of electricity (this market operates in a similar fashion to the Alberta wholesale market); however, after restructuring, legislation was introduced to impose price caps for low volume consumers (e.g. residential consumers), resulting in a market that is not fully competitive.
5.2.8 Carbon capture and storage
Canada is home to one of the world’s first, and still one of the world’s largest, CCS demonstration projects in Weyburn, Saskatchewan. Using CO2 to enhance the oil production from depleting oil reservoirs at Weyburn and Midale, Saskatchewan, this commercial project has been successfully demonstrating the safe underground storage of CO2 — over 16 Mt of CO2 has been injected since the start of the project. This project is also serving as a field laboratory for an international collaborative research project, launched in 2000, with the goal of developing and implementing effective and reliable CO2 measuring, monitoring and verification methodologies. As a founding member of this initiative, the federal government, along with many private and public sector partners, has been a key contributor.
In April 2011, SaskPower formally announced the incorporation of CCS technology at one of its coal-fired units. The Boundary Dam Integrated Carbon Capture and Storage Demonstration Project, a partnership involving the Government of Canada, the Government of Saskatchewan, SaskPower and private industry, will examine CCS’s economic, technical, and environmental merits. The project will be among the first commercial-scale post combustion CCS facilities in the world. The captured CO2 is expected to be used in enhanced oil recovery, while captured SO2 is expected to be used in the production of sulphuric acid and other products.
6. Regulatory and non-regulatory options considered
The Government of Canada is committed to reducing Canada’s total greenhouse gas emissions by 17% from 2005 levels by 2020. To meet this target, Canada has stated that it will proceed with strong domestic, continental and international action, including the introduction of new regulations on coal-fired electricity generation.
The Regulations to address CO2 emissions from coal-fired electricity generation are considered the most effective instrument as they provide the necessary certainty and efficiency in achieving the objective of reducing GHG emissions from the electricity generation sector. Voluntary approaches would not be able to provide assurance of significant emission reductions from this sector and the level of certainty needed to support industry investment.
Within the existing regulatory framework, two options were considered: cap-and-trade system and performance standard.
Regulatory option 1: Cap-and-trade system for the thermal electricity sector under CEPA 1999
Cap-and-trade is a policy instrument that places a mandatory cap on emissions through the distribution of emissions permits up to a pre-determined level, while providing regulated facilities with flexibility in how they will operate within the limited number of emissions permits available to them. Regulated facilities could reduce their emissions through, for example, installation of abatement technologies, changing production processes or by buying permits from sources that can abate emissions at a lower cost. Under appropriate conditions, cap-and-trade can provide high certainty in reaching an environmental objective cost effectively, while promoting new avenues for economic growth and innovation.
However, certain fundamental conditions are necessary for cap-and-trade to work effectively. First, the marginal costs of abatement across facilities must be different so that there are gains from trade and surplus permits are generated. Second, there must be a significant number of facilities to ensure the functioning of an efficient and liquid trading market. For example, the European Union Emissions Trading System (EU ETS) — the world’s first international cap-and-trade system for CO2 emissions — currently covers about 11 000 heavy energy consuming installations in power generation and manufacturing across 30 countries.
In the Canadian electricity generation sector, neither of these conditions exists to a degree which makes cap-and-trade exclusively for coal-fired electricity a viable option. The Canadian electricity system is already among the lowest-emitting in the world, with coal-fired generation representing about 15% of the total electricity produced. This means that a cap-and-trade for electricity would be targeting only 45 units of coal-fired generating units across the whole country (as of 2012), and an even smaller number of operating entities/corporations. At the same time, there are relatively small variations in marginal costs across these units, making it unlikely that many of them could generate surplus emissions permits.
These factors would lead to significant constraints on trading opportunities, which in turn would lead to low levels of market liquidity and create a risk of large fluctuations in the price of carbon permits. A fluctuating price of carbon presents a significant additional uncertainty for investors and consumers. This would make it difficult for companies to control costs and plan appropriately, and create great price uncertainty for electricity consumers. It would also limit their ability to align the construction of new facilities with normal capital investment/useful life cycles in order to achieve a smooth transition to lower-emitting fuels and/or technologies. A constrained carbon market for coal-fired generators would also be vulnerable to manipulation by one or two large facilities, a situation that is magnified in Canada by the preponderance of provincially owned utilities in the sector.
Regulatory option 2: Performance standard regulations for coal-fired electricity generating units under CEPA 1999
The Regulations for the coal-fired electricity sector will set a stringent performance standard for new coal-fired units and those that have reached the end of their useful life. The performance standard will ensure a corresponding transition towards lower- or non-emitting types of generation, such as high-efficiency natural gas, renewable energy, or fossil fuel-fired power with carbon capture and storage.
The performance standard approach is administratively simpler and more efficient to implement compared to a cap-and-trade system, as it does not require the creation of a complex trading system to address emissions from a relatively narrow sector of the overall economy. The use of a performance standard that does not specify the fuel or technology to be used increases the potential for innovative response.
In doing so, the Regulations provide regulatory certainty for the coal-fired electricity sector at a time when the sector is facing major capital stock turnover. This regulatory certainty allows utilities to factor GHG emissions considerations into their plans for replacement of end of useful life units, to align those investments with capital stock turnover cycles to better control costs, and to avoid the risk of stranded assets.
Given the above considerations, a regulated performance standard was determined to be the preferred approach to address GHG emissions from the coal-fired electricity generation sector. Through consultations, industry and provincial stakeholders have expressed general support of the regulated performance standard approach with consideration of specific issues.
Taking action now to regulate coal-fired electricity generation will achieve multiple economic and environmental objectives for decades by providing investors, utilities, and electricity consumers with a regulatory environment that leads to both efficient and more certain reductions in CO2 emissions from this sector as well as reductions in a wide range of air pollutants that negatively affect human health and the environment. This regulatory approach will avoid the lock-in of long-lived dirty electricity infrastructure that would increase the costs of reducing greenhouse gas emissions in Canada in the future.
7. Benefits and costs
Several notable changes have been incorporated into the cost-benefit analysis since the CGI publication to reflect comments received and to incorporate new data. Along with the incorporation of the policy changes to the Regulations proposed in CGI, consultations with provincial, territorial, and industry officials have resulted in significant adjustments to the parameters underlying the projections for both the business-as-usual (BAU) and regulatory scenarios, and new data such as updated capital costs and fuel prices have been incorporated into the CBA.
Saskatchewan officials indicated that the provincial utility intends to implement CCS technology as a response to the regulatory performance standard. Where the captured CO2 is used for enhanced oil recovery, it generates additional benefits as a result of incremental oil production. The CGI analysis had assumed new natural gas capacity, increased utilization rates of existing units, and increased net imports were the most efficient way to meet the standard for all provinces.
Consultations with Nova Scotia government officials resulted in the inclusion of the provincially regulated 40% renewable mandate and increased impacts of demand-side management (DSM) programs. The CGI analysis had incorporated a 20% renewable mandate, as it was the only renewable program legislated at the time.
Alberta officials were able to provide additional insight and details into their unique market structure, allowing E3MC to better capture the way their competitive system would interact with the Regulations. This led to larger price impacts, which had an impact on the demand response and caused a larger incremental decrease in electricity demand relative to CGI.
The purpose of this CBA section is to describe the major policy and modelling changes and present the expected impacts stemming from the revised analysis. Impacts are highly concentrated in Alberta, Saskatchewan, and Nova Scotia. Hence, these provinces are the focus of the CBA section.
Summary
The Regulations will ensure a permanent transition to lower- or non-emitting types of electricity generation, which will have significant impacts on many stakeholders. It is estimated that, over a period of 21 years, 6 820 MW of coal-fired electricity capacity will be retired or avoided due to the Regulations, with the majority of retired and avoided capacity occurring in Alberta (74%), followed by Nova Scotia (14%), and Saskatchewan (11%). At the same time, it is estimated that 3 513 MW of incremental natural gas capacity will be added by 2035, with the largest additions in Alberta.
The owners and operators of electricity generating facilities can respond to the Regulations in several manners. In Environment Canada’s economic modelling of the Regulations, the majority of retired coal-fired generating capacity is replaced with natural-gas fired generation, while three coal-fired plants are expected to employ carbon capture and storage technology. The rest of the generation comes either from increased production from existing plants or through a combination of reduced exports and increased imports to and from the United States. Each of these alternatives imposes costs on the electricity sector, which in turn are expected to be largely passed on to consumers in the form of higher prices for electricity, which will result in reduced demand for electricity.
The incorporation of natural-gas fired generation and carbon capture and storage technology results in significant health and environmental benefits for Canadians in the form of reduced GHG emissions and criteria air contaminant (CAC) emissions. With the application of CCS, captured CO2 can be used for enhanced oil recovery (EOR), which increases the amount of oil that can be recovered from wells while at the same time permanently storing the CO2 underground. Overall, the estimated benefits of the Regulations greatly outweigh the estimated costs. A list of quantified and/or monetized impacts is presented in Table 4.
In summary, the NPV of the Regulations in 2015 over the study period is estimated at $7.3 billion. The present value of the benefits is estimated at $23.3 billion, largely due to the avoided costs of climate change ($5.6 billion), avoided generation costs ($7.2 billion), health benefits from reduced smog exposure ($4.2 billion), and additional oil extracted through enhanced oil recovery ($6.1 billion). The present value of the costs is estimated at $16.1 billion, largely due to incremental purchase of natural gas fuel ($8.0 billion), oil extraction costs for enhanced oil recovery ($1.3 billion), reduced exports ($0.3 billion) and new capital ($1.9 billion).
In contrast to the CGI analysis, the NPV of the Regulations has increased substantially from $1.5 billion to $7.3 billion. This increase is largely attributable to the timeframe of the analysis, which was extended outwards from 2015–2030 to 2015–2035 to adequately capture the longer-term impacts of the Regulations and the inclusion of costs and benefits associated with CCS technology and enhanced oil recovery.
Table 4: Monetized Benefits and Costs of the Regulations
Benefits | Costs |
---|---|

7.1 Analytical framework
The standard approach to cost-benefit analysis is to identify, quantify and monetize the incremental costs and benefits of the Regulations. In this analysis, incremental impacts have been estimated in monetary terms to the extent possible and are expressed in 2010 Canadian dollars except when otherwise noted. Where this was not possible, due either to lack of appropriate data or difficulties in valuing certain components, incremental impacts were evaluated in qualitative terms. Finally, it should be noted that the numbers and percentages as presented in tables may not be completely consistent due to rounding.
The cost-benefit analysis framework applied to this study incorporates the following elements:
7.1.1 Scope of the analysis
The cost-benefit analysis presented in CGI examined the impacts of displacing coal-fired generation with generation from new natural gas capacity and increased utilization of existing units and changes in trade flows. Therefore, the scope of the analysis was limited to the electricity and coal sectors. To examine the impact of the proposed Regulations on natural gas price, Environment Canada commissioned a report from Ziff Energy (section 7.7.2).
During an extensive consultation process after CGI publication, Saskatchewan officials indicated that under the Regulations, SaskPower would employ CCS technology to meet the performance standard. The benefits of employing CCS for Saskatchewan include life extension of existing coal-fired units, continued use of a low cost and naturally abundant fuel in an environmental sustainable manner, continued existence of the province’s traditional coal sector, and extraction of stranded oil. The costs of expanded CCS are expected to manifest themselves in the form of substantial costs for retro-fitting facilities to be CCS compliant and higher electricity prices for electricity consumers in Saskatchewan relative to the BAU scenario.
The decision to respond to the Regulations through the expansion of coal CCS has resulted in additional cost and price impacts above and beyond what were considered in the CGI analysis. Major benefits of electricity generation through coal CCS units are reduced CO2 emissions and increased productivity of oil extraction. To capture the effects of EOR, the analysis has been expanded to include the oil extraction sector.
7.1.2 Timeframe for analysis
Due to the new definition of end-of-life, (see footnote 23) as described under section 5.1, the regulated retirement dates for several coal-fired units have been postponed. To align with the new end-of-life definition and present an analysis that adequately captures the longer-term costs and benefits, the study period was extended from 16 years (2015–2030) to 21 years (2015–2035). This decision also addresses a comment which stated the CGI analytical timeframe was too short. The first year of the analysis is 2015, when the Regulations come into effect.
7.1.3 Discount rate
A social discount rate of 3% is used in the analysis for estimating the present value of the costs and benefits in 2015 under the central analysis. This is consistent with the Treasury Board Secretariat’s cost-benefit analysis guidelines and is what was used in CGI. This is consistent with the discount rates that have been used for GHG-related measures in Canada, as well as that being used by the U.S. EPA. Costs and benefits were discounted to base year 2015, the first year the Regulations come into effect. A sensitivity analysis of the discount rate was conducted to test the robustness of the results.
7.1.4 Incremental impact
Impacts are analyzed in terms of incremental changes to emissions, costs and benefits to stakeholders and Canadian society. The incremental impacts were determined by comparing two scenarios: the business-as-usual (BAU) scenario and the regulatory scenario. The two scenarios are presented in detail below.
It is important to note that the analysis presented below for the BAU and regulatory scenarios are performed using the E3MC modelling results. While based on the best information currently available, these results present one possible scenario which, like all long-term projections, is subject to significant uncertainty regarding specific projections, e.g. regarding specific new plants, retirements, or other data and assumptions.
7.1.5 BAU scenario
The BAU establishes what the electricity sector is expected to look like in the future without the Regulations. This scenario was established for the CGI analysis (CGI BAU) by incorporating pre-existing federal (see footnote 24) or provincial policies (see footnote 25) including the Ontario coal phase-out as described in section 5.2.5; economic and demographic factors that affect the electricity market such as population and housing development; and private decisions to build a new unit or retire an old unit, etc.
Since the publication of the CGI analysis, several changes have been made to the BAU scenario to reflect comments received and to incorporate new data. Notable changes from CGI include new information on plant closure and replacement decisions:
- Two units at Sundance were closed in 2011 and hence are no longer relevant for the analysis. These units were previously included in the CGI BAU and were affected by the proposed Regulations.
- H. R. Milner was assumed to be retired in 2014 in the BAU and hence not affected by the proposed Regulations. In this revised analysis, this plant is included in the BAU and affected by the Regulations.
- Coleson Cove was assumed to continue to operate indefinitely in the CGI BAU. In the CGII BAU, it retires in 2031, while under the Regulations it retires one year earlier.
- Nova Scotia’s renewable energy target of 40% in 2020 and demand side management plans are now completely incorporated. Full details on these measures were not available at the time of CGI. The analysis also now includes exports from the Muskrat Falls facility, which is part of the Lower Churchill project, to Nova Scotia via a link between Newfoundland and Labrador.
- Projected population growth in Nova Scotia and Alberta’s industrial electricity demand were revised as a result of consultations with provincial officials.
- Keephills 3 was modeled to employ CCS technology (Project Pioneer) in the CGI BAU. The analysis for CGII excludes Project Pioneer due to the recent announcement that the project will not proceed.
Presented below are the unit retirements and new coal and gas units under the BAU for the revised analysis.

Table 5 shows the coal unit retirements (closures) under the BAU. All retirements except one in New Brunswick occur by the year 2015. Overall, 7 520 MW of capacity and 22 units are retired, largely driven by the Ontario coal phase-out which accounts for 6 077 MW and 15 units of 22 units retiring under the BAU. (see footnote 26) In total, 45% of the total coal capacity as of 2010 is assumed to be retired by 2031.
Table 5: Coal-fired Unit Retirements in the BAU Scenario
Region | Units | Retirement Years (see footnote 27) | Coal Capacity Retired (MW) | Coal Capacity in 2010 (MW) | Retired 2010 Canadian Capacity |
---|---|---|---|---|---|
Alberta | 3 | 2011 | 900 | 6 305 | 5% |

With almost 50% of the coal-fired capacity retiring, the construction of coal and natural gas plants is required in order to meet electricity demand. Overall, 2 534 MW of new coal capacity are projected to be constructed or rebuilt — three new industry-announced units (for a total of 1 219 MW) and three which are projected to be built by E3MC (for a total of 1 200 MW) in Alberta, (see footnote 28) and a rebuilt unit in Saskatchewan (115 MW). (see footnote 29) Two of the new units (i.e. Swan Hills and Boundary Dam 3) are modelled to employ CCS technology to align with recent announcements. Furthermore, 13 541 MW (see footnote 30) of additional net gas capacity is projected to be built by 2035. The additions are primarily in Ontario (6 502 MW), Alberta (6 543 MW), and Saskatchewan (1 727 MW), while Nova Scotia and Manitoba add 52 MW and 550 MW of capacity respectively. (see footnote 31)
For other units, it is assumed they do not automatically retire at the end of their useful life, but instead are refurbished at an estimated cost of around $395/kW (see footnote 32) (undiscounted) and continue generating electricity as the lowest cost option for another 25 years.
7.1.6 Regulatory scenario
The regulatory scenario establishes what the electricity sector is expected to look like with the implementation of the Regulations. For the CGI analysis, E3MC was used to assess the impacts of the proposed Regulations, which required owners and operators to meet a performance standard of 375 tonnes of CO2/GWh. Following an extensive consultation and to address stakeholders’ concerns, the emission performance standard increased from 375 tonnes to 420 tonnes of CO2/GWh. The definition of end-of-life was also revised to mitigate impacts as described in section 5.1.
It is expected that utilities, whether privately owned or Crown owned, will choose to implement the compliance option that maximizes their net benefits and meets their objective, should it be social or private, in meeting the performance standard. The responses to the performance standard include new natural gas capacity, increased utilization of existing units, and the deployment of CCS. As shown in the CGI analysis, new natural gas capacity and increased utilization rates of the existing units were the most efficient ways to meet the standard for all provinces.
However, after the publication of the CGI analysis, Saskatchewan officials indicated that over the long term, CCS is the most effective means of compliance in consideration of the potential impacts of the Regulations on its traditional coal mining sector as well as the potential to realize benefits from EOR by using captured CO2. As a result, the revised analysis assumes Boundary Dam units 4, 5, and 6 continue to operate with carbon capture and storage under the regulatory scenario. In the CGI analysis, Boundary Dam units 4, 5, and 6 were assumed to be retired due to the proposed Regulations.
The deployment of CCS entails significant capital costs. For example, as presented in “EOR, An Opportunity for Alberta, Alberta Economic Development Agency, January 2009,” the cost of capturing and sequestering is estimated to be about $80/tonne in the early years. Part of this cost can be recovered from selling CO2 for use in EOR. However, when considering the economics of EOR, the cost of the CO2 must be in the range of about $20/tonne–$40/tonne to make an EOR project viable. This still yields a range of a net cost of $40–$60/tonne. (see footnote 33) In facing the Regulations, from a societal perspective, the use of CCS to capture CO2 emissions would result in the continued use of locally abundant coal resources, allow for the retention of employment in coal-fired generation plants and coal mining, incremental oil production, and generate employment and other economic opportunities (e.g. Canadian suppliers to these projects could be well positioned to export their technologies to the rest of the world). The collection of CO2 revenues, royalties, and corporate income taxes, all due to increased economic activity from the deployment of CCS, and higher electricity prices, help to close the gap in the net cost per tonne of CCS deployment from the provincial perspective.
The scope of the analysis has been extended to include the costs and benefits of the incremental oil extraction. In estimating the costs and benefits, the following assumptions are made:
- Costs of EOR are $6/barrel (bbl) of oil produced for capital, $9/bbl for O&M, $9.60/bbl for CO2 recycle costs. (see footnote 34)
United States Department of Energy, Improving Domestic Energy Security and Lowering CO2 Emissions with “Next Generation” CO2-Enhanced Oil Recovery (CO2-EOR), June 20, 2011, Table V-1. These figures were also considered rel-evant within the Canadian context by EC experts. - GHG emissions are assumed to increase as per the average emissions per bbl of Canadian conventional oil production.
- For the central case, oil has been valued at the forecasted price of West Texas Intermediate (WTI) from E3MC, which is based on National Energy Board (NEB) projections.
- The use of one tonne of CO2 for EOR results in three incremental bbl of oil production. (see footnote 35)
Coal-fired unit retirements and compliance flexibility options
Under the regulatory scenario modelled, coal units retire (close) at the end of their useful life or continue operating if they employ CCS. Although compliance flexibility options are available to all units that meet the criteria, for the purposes of modelling and based on expected responses to the Regulations, they were accounted for in the analysis as follows:
- Substitution: This flexibility was modelled to affect Nova Scotia. Trenton 5 swaps with Lingan 1, and Point Tupper 1 swaps with Lingan 2.
- CCS Deferral: The flexibility was modelled to affect Boundary Dam units 4 and 5 in Saskatchewan so that these units will not be required to meet the performance standard until 2025.
- Fuel switching: Point Tupper 1 (subsequently transferred to Lingan 2) and Coleson Cove 3 all have 18 months added to their end of life for re-commissioning to burn coal from oil.
Table 6 shows the coal units that are expected to retire by 2035 as a result of the Regulations. Overall, 5 452 MW of capacity and 20 units are retired, predominantly in Alberta (3 366 MW), which represents 62% of retired capacity.
Decommission costs of (undiscounted) $96/KW (see footnote 36) are assumed for coal units closed due to the Regulations. A sensitivity analysis is provided in section 7.6 to account for the large variation in decommissioning costs.

7.2 Economic tools, data and information sources
This analysis uses various sources, including a significant amount of data provided by provincial officials during the extensive post-CGI consultations.
7.2.1 Capacity, generation, emissions
This analysis is based on the modelling results done by Environment Canada (EC) using its E3MC model. Specifically, data on capacity, demand, generation, GHGs (CO2e), CACs, and mercury emissions for both BAU and regulatory scenarios were populated from E3MC.
The Energy, Emissions and Economy Model for Canada has a dynamic view of the electricity system. When one unit closes, generation will be replaced with the least expensive option. Therefore, coal-fired unit closures will not always be replaced with a new plant if there are other less expensive options available. For example, in some cases, the most economically attractive option may be to compensate for lost generation from retiring coal-fired generation with additional generation from existing units with surplus capacity.
It is important to note that E3MC’s results provide only a central point estimate, projecting one plausible scenario of the many future pathways of generation and emissions. The projection reflects a wide range of assumptions that are based on expert-driven knowledge and both public and private data as of April 2012. As with any projection, these assumptions will ultimately differ from reality. For example, some coal-fired units assumed to close in the BAU scenario may not close in reality (and vice versa). Changes to key assumptions (e.g. macroeconomic outlook, utility plans, or development in commercially available technologies) would lead to different outcomes.
7.2.2 Fuel prices
The natural gas price projection used in the CGI analysis was based on the most up-to-date forecast available at the time, which came from Natural Resources Canada. Subsequently, the natural gas price projection has been updated to reflect a more recent forecast. These prices are somewhat higher than the CGI prices. Section 7.6.2 contains the results of a sensitivity analysis on the impact of future natural gas prices on consumer prices.
Projections of natural gas and coal prices to utility by province used in this analysis are based on estimates generated by E3MC, which are based on historical natural gas and coal costs for utilities by province from Statistics Canada. These historical prices are then grown by the projected growth rate of natural gas and coal prices from the National Energy Board (NEB). (see footnote 37) These prices are shown for key provinces in Figures 3a and 3b. In general, the price of natural gas in one region differs from the price in another region only by the cost of transportation to get the gas to the end user.
While coal is produced in Alberta and Saskatchewan, Manitoba and Nova Scotia are dependent on imports. Manitoba generally imports coal from North Dakota for coal-fired generation, while Nova Scotia purchases bituminous coal on the international market that is generally of higher quality than the sub-bituminous and lignite coal used in Western Canada.
The NEB forecast underlying the natural gas prices used in the analysis projects an increase from US$4.50/MMBtu in 2011 to US$8.00 in 2035 at Henry Hub (in U.S. 2010 dollars). This could be considered conservative, as the most recent U.S. Energy Information Administration forecast (Annual Energy Outlook 2012 [AEO2012]) projects much slower price increases, reflecting the continued industry success in tapping extensive shale gas resources in the United States, which has led to a 19% increase in U.S. natural gas production since 2006. Particularly, forecast prices for natural gas remain below US$5 through 2023, and then start to increase as production gradually shifts to resources that are less productive and more expensive, with the price rising to US$6.53 by 2035.
The coal price forecast underlying the prices used in the analysis remains relatively flat at 2011 prices throughout the forecast period for all provinces. The majority of coal imported to Nova Scotia for electricity generation comes from the United States, and the average price of coal increases by 1.4% per year in the AEO2012 reference case.
The modelling results find no change in these projected prices due to the Regulations. For natural gas, independent research (see footnote 38) commissioned by Environment Canada concluded that an increase in demand of less than 1% in the overall North American market, as is the case for the Regulations, would not have a significant effect on natural gas prices.
The analysis also employs WTI oil price forecasts in its monetization of EOR. This price forecast is taken from E3MC, which is also based on the NEB forecast.
Figure 3a: Forecasted Natural Gas Prices — E3MC (2015–2035)
Figure 3b: Forecasted Coal Prices — E3MC (2015–2035)
7.2.3 Import and export prices of electricity
The price forecasts for imports and exports of electricity are calculated within E3MC based on the historical mix and outlook of future mix of short- and long-term electricity export contracts. The prices of short-term and long-term electricity contracts vary systematically; thus assumptions on the future contract mix will influence forecasted prices. Imports from the United States are based on the weighted average cost of power from the importing area.
7.2.4 Air quality modelling
To estimate how these emission reductions will impact human health and the environment, Environment Canada first used A Unified Regional Air-Quality Modelling System (AURAMS) to predict how the emission changes will affect local air quality. (see footnote 39) This is a fully three-dimensional state-of-the-art numerical model described in peer-reviewed scientific literature. (see footnote 40) AURAMS combined the information on predicted emission changes, with information on wind speed, temperatures, humidity levels, and existing pollution levels, in order to predict how these emissions changes will impact local air quality. (see footnote 41)
The CAC emissions (and resulting changes) are determined using emissions coefficients based on the 2009 National Pollutant Release Inventory (NPRI). The coefficients are determined by dividing a specific emission for 2009 by an economic driver for 2009 (e.g. volume of fuel used or volume of output). The results are then inputted into AURAMS.
7.2.5 Health and environmental benefits resulting from CAC reductions
The reductions in CAC emissions improve air quality, resulting in health and environmental benefits. Environmental benefits are estimated using Environment Canada’s Air Quality Valuation Model (AQVM2). Health risks and impacts are estimated by Health Canada using the Air Quality Benefits Assessment Tool (AQBAT). (see footnote 42)
7.3 Costs
7.3.1 Demand
As stated above, the demand for electricity used in this analysis is obtained from Environment Canada’s E3MC model. Under the BAU, the total demand for electricity is projected to increase from 538 TWh in 2015 to 652 TWh by 2035 (Table 7).
Under the regulatory scenario, relative to the BAU, the demand for electricity declines slightly by 2035, from 652 TWh to 646 TWh. This 6 TWh (0.79%) reduction is primarily attributable to the response of the industrial sector to the price impacts of the Regulations.

7.3.2 Capacity
Under the regulatory scenario, incremental to the BAU, coal-fired electricity generating capacity is expected to be reduced by 6 820 MW by 2035 (Table 8). This is mainly due to the 20 coal units retired (Table 6) but it is also due to avoided coal builds. Overall, 3 513 MW of incremental natural gas capacity is added by 2035 with the largest additions in Alberta, followed by Nova Scotia (Table 8). Minor additions in renewable capacity are also projected to occur. The net reduction in capacity (-3 290 MW) is the product of provinces leveraging existing capacity that is under-utilized to comply with the Regulations. More specifically, under the BAU,
- the average capacity utilization at coal-fired units in Canada is 91% by 2035 (increasing to 95% under the regulatory scenario); and
- the average capacity utilization at natural gas-fired units in Canada is 43% by 2035 (increasing to 54% under the regulatory scenario).

Note that Sundance 7, 8, and 9 are expected to come on line as natural gas plants as advised by Alberta. Therefore, these units are added to the regulatory scenario. In costing the new capacity (capital, average fixed O&M, and average variable O&M costs), Environment Canada uses publicly available information such as the U.S. Energy Information Administration’s AEO 2011 and input from stakeholders for some specific units.
7.3.3 Generation
As coal plants shut down, both in the BAU and in the regulatory scenario, and natural gas units are built, a change in generation mix occurs. Under the BAU, coal-fired electricity generation remains at 69 TWh in 2015 increasing to 79 TWh by 2035 (Table 9). Over the same period, natural gas generation increases from 56 TWh in 2015 to 87 TWh in 2035.
Under the regulatory scenario, coal-fired generation decreases to 65 TWh by 2025, reaching 35 TWh by 2035 (55% decrease from the BAU). Of these 35 TWh generated by coal-fired generation, 8 TWh are estimated to be generated by coal CCS. In 2035, around 68% of Saskatchewan’s total coal generation is projected to be from coal CCS. Moreover, natural gas generation increases to 79 TWh by 2025, reaching 126 TWh by 2035 (44% increase from BAU). There is a negligible impact on non-emitting generation.

Over 2015 to 2035, relative to BAU, there is a total reduction in coal-fired generation of 298 TWh (Table 10) from provinces primarily affected by the Regulations (Alberta — -252; Saskatchewan — -27; Nova Scotia — -20). This displacement of generation from coal-fired units is mostly offset by a 256 TWh increase in natural gas generation (Alberta — 222; Saskatchewan — 22; Nova Scotia — 8). This yields a reduction in generation of 39 TWh, which is mainly due to reduced demand.

7.3.4 Imports and exports of electricity
Under the BAU, electricity imports would increase from 14 TWh in 2015 to 19 TWh by 2035 (Table 11). Over the same period, electricity exports would increase from 68 TWh in 2015 to 86 TWh in 2025, and then decline to 85 TWh by 2030 and to 77 TWh in 2035. The sharp decline in electricity exports post 2030 is projected to occur because, over time, under the BAU, the excess capacity previously being exported is being relied upon to meet the domestic market (e.g. new capacity is not built to support the export market).
Under the regulatory scenario, electricity imports would increase to 19 TWh by 2035 (2% increase from BAU). Moreover, electricity exports would increase to 86 TWh by 2025, and then decline to 83 TWh by 2030, and to 76 TWh by 2035 (2% decrease from BAU). The Regulations would cause Canada to rely marginally more on imports, while reducing its electricity exports since a greater portion of its capacity would now be required to accommodate the demand from the domestic market. As imports increase and exports decrease, net electricity imports increase, although it should be noted that Canada remains a net exporter of electricity and imports will still represent a small share of overall electricity demand in Canada under the Regulations.

7.3.5 Interprovincial trade flows
As a result of the Regulations, there will likely be some key shifts in interprovincial electricity trade flows. These would be required to support the displaced coal-fired generation from affected provinces. More specifically, relative to BAU, over 2015 to 2035,
- Nova Scotia exports less to New Brunswick (5 TWh) and imports more from New Brunswick (2 TWh);
- Manitoba exports more to Saskatchewan (8 TWh) and imports more from Ontario (1 TWh); and
- Quebec exports more to New Brunswick (1 TWh) and imports less from New Brunswick (1 TWh).
Environment Canada’s modelling assumed that no new infrastructure would be built to allow a significant increase in electricity trade. While Environment Canada’s model has the capacity to build interprovincial and international flows, due diligence was undertaken to ensure that provincial plans are fully respected (i.e. the model only builds new transmission that is provided in provincial plans). If new infrastructure is built, then the model includes the full cost related to the building of the new transmission capacity.
7.3.6 Costs and avoided costs to the electricity sector
Table 12 shows the present value of various major costs and avoided costs under the Regulations. Over the 2015 to 2035 time period, the Regulations would force traditional coal plants to retire, promoting the expansion of plants with lower levels of greenhouse gas emissions.
When a coal plant closes, there is a cost of decommissioning the plant, and a savings associated with the avoided fixed and variable O&M costs, as well as the avoided coal costs and avoided future refurbishments. However, since the period of study ends at 2035, the residual value of the avoided refurbishments is netted off by amortizing the initial costs over the expected lifetime of the investment to ensure that only benefits accrued within the study period are included in the calculations.
When a natural gas or coal CCS plant opens there are costs associated with it, including new capital investments, fuel costs, as well as additional fixed and variable O&M costs. Once again, the residual value of the new capital investments is netted off to ensure that only costs within the period of study are analyzed. This is done using the same methodology as with the residual value of the avoided refurbishments.
Finally, the Regulations prevent some planned coal units from being built. These avoided builds come with benefits of avoided capital investments (and their residuals, treated in the same manner as described above), as well as avoided coal fuel costs and avoided fixed/variable O&M costs.
The present value of capital costs (including avoided refurbishments, additional capital and avoided capital investments, and their corresponding residuals) increases by $67 million over the study’s time period. The present value of the net fuel costs (netting the coal savings from the natural gas costs) increases by $4,461 million. The present value of the net fixed O&M costs decreases by $582 million, while the present value of the net variable O&M costs increases by $2,778 million. The cost of decommissioning the retired coal plants comes to a present value of $329 million. Overall, generation costs for the electricity utility generation sector increase by $7,052 million over the study period due to the Regulations.

Table 13 shows the present value of the change in generation costs for key provinces. Over 2015 to 2035, the largest increase would be for Alberta ($5,882 million), followed by Saskatchewan ($1,174 million), Manitoba ($95 million) and Nova Scotia (-$217 million).

Alberta
The majority of the incremental generation costs in Alberta due to the Regulation are fuel and O&M costs. Net capital costs are negative because the avoided costs for refurbishment and capital are greater than the capital investment in natural gas. The incremental fuel costs are much greater because of the spread between coal and natural gas prices to electric utilities.
Nova Scotia
The Regulations create incremental avoided generation costs for Nova Scotia. Although the cost of additional plant builds is greater than the avoided builds, the additional avoided refurbishment costs associated with the decommissioned plants causes a net avoided capital cost.
In addition, despite the increase in unit fuel costs due to the spread between natural gas and coal prices to electrical utilities, Nova Scotia experiences a decrease in total fuel costs. This is because coal generation decreases by over two times the amount that natural gas generation increases, partially as a result of Nova Scotia’s DSM policies, but also due to decreased interprovincial exports and increased interprovincial imports. (see footnote 49)
Saskatchewan
A large portion of the incremental generation costs are due to the capital costs of CCS. There are also increases in fuel costs as more generation moves from coal to natural gas.
7.3.7 Foreign imports/export costs
Over 2015 to 2035, cumulative U.S. electricity imports would increase by an incremental 4 TWh while cumulative exports decline by 13 TWh (Table 14). The reduction in coal generation would cause provinces to reduce their supply to the United States since this capacity would now be required to serve the domestic market. The increase in imports occurs in Saskatchewan and British Columbia, while reduced exports occur predominantly in New Brunswick, Manitoba, and Saskatchewan with smaller reductions in British Columbia and Ontario.
The value of foreign cumulative imports of electricity was determined by multiplying the change in imports by price. The price forecasts for imports and exports are calculated within E3MC as described above in section 7.2.3. Actual flows of electricity are determined annually and constrained by transmission capacity.
Over 2015 to 2035, the total present value of increased cumulative electricity imports is $72 million, with the largest increases in Saskatchewan ($65 million) and British Columbia ($11 million). The value of reduced cumulative foreign exports represents the foregone revenues. Over 2015 to 2035, the present value of reduced electricity cumulative exports would be $274 million, with the largest losses in New Brunswick ($152 million) and Saskatchewan ($69 million).

7.3.8 Oil extraction costs
One of the benefits of the Regulations is increased oil production through EOR with captured CO2 from CCS plants. The costs associated with this benefit are capital, fixed and variable O&M costs for oil extraction, and GHG emissions associated with this oil extraction. It should be noted that royalties, taxes and the cost of CO2 purchases represent transfers from one Canadian stakeholder to another, and are therefore excluded from the cost of production in the cost-benefit analysis, as per standard practice. Over the span of the Regulations the present value of the oil production costs is estimated to be $1,288 million, and the present value of GHG emissions is estimated to be about $140 million (for more details on how the value for GHG emissions is calculated, please refer to section 7.4).
7.3.9 Government costs
The federal government would incur incremental costs related to training, inspections, investigations, and measures to deal with any alleged violations, and compliance and promotion activities.
With respect to enforcement costs, one-time amounts of $142,000 for the training of enforcement officers and $50,000 to meet information management requirements will be required.
The annual enforcement costs are estimated to be about $105,000 broken down as follows: roughly $66,000 for inspections (which includes operations and maintenance costs and transportation and sampling costs), $16,000 for investigations, $2,000 for measures to deal with alleged violations (including warnings, environmental protection compliance orders and injunctions) and about $21,000 for prosecutions.
With respect to compliance promotion, in the first five years after the coming into force of the Regulations, activities are expected to be limited to inform the electricity sector of the reporting requirements. Compliance promotion activities, during this period, will be covered by routine administrative costs that are not considered incremental. Activities are expected to increase as units reach their end-of-life. This will result in additional costs for compliance promotion of $45,000 nominal in 2019 followed by an expense of $10,000 per year for the subsequent two years. Compliance promotion activities could include training of compliance promotion officers, information management, mailing out of the final Regulations, developing and distributing promotional materials (e.g. a fact sheet, Web material), responding to inquiries, attending trade association conferences, sending reminder letters, etc.
In addition to enforcement and compliance activities, the costs are estimated to be about $795,000 during the first year of the implementation of the Regulations. This includes the development of an electronic data entry system to support the reporting requirements. In subsequent years, the costs are estimated to be about $575,000 per year to administer the Regulations.
Over 2015 to 2035, the present value of government costs would be about $11 million.
7.4 Benefits
7.4.1 Benefits from GHG reductions
Since the GHG emissions generated from natural gas and coal CCS are significantly lower than coal, this would result in fewer GHG emissions. The coal emission factors differ by province due to the fact that different types of coal are available in different parts of the country. These emission factors are assumed to remain constant over the projection period. Natural gas emission factors do not vary across provinces or over the projection period.
Over 2015 to 2035, there would be cumulative reductions in GHGs from the utility sector as a whole, relative to BAU, of approximately 219 Mt (Table 15). (see footnote 50) The largest reductions would be in Alberta (160 Mt), followed by Saskatchewan (45 Mt) and Nova Scotia (15 Mt). These reductions are above and beyond existing and assumed federal and provincial actions. Figure 4 shows the GHG emissions in the electricity sector under the BAU and regulatory scenarios.

Figure 4: GHG Emission Profile
The estimated value of avoided damages from GHG reductions is based on climate change damages avoided at the global level, given that climate change is a global issue and it is not possible to directly associate climate change damages in any given region with greenhouse gas emissions from that region. The value placed on anticipated climate change damages is usually referred to as the social cost of carbon (SCC). Estimates of the SCC vary widely due to challenges in predicting future emissions, climate change, damages and determining the appropriate weight to place on future costs relative to near term costs (discount rate).
Social cost of carbon values used in this assessment draw on work undertaken by Environment Canada in collaboration with an interdepartmental federal government technical committee, and in consultation with a number of external academic experts. (see footnote 51) This work involved reviewing the existing literature and other countries’ approaches to valuing greenhouse gas emissions. Preliminary recommendations, based on current literature and in line with the approach adopted by the U.S. Interagency Working Group on the Social Cost of Carbon, (see footnote 52) are that it is reasonable to estimate SCC values at $26/tonne of CO2e in 2010, increasing at a given percentage each year associated with the expected growth in damages. (see footnote 53) Environment Canada’s review also concluded that a value of $104/tonne in 2010 should be considered for sensitivity analysis, reflecting arguments raised by Weitzman (2011) (see footnote 54) and Pindyck (2011) (see footnote 55) regarding the treatment of right-skewed probability distributions of the SCC in cost-benefit analyses. (see footnote 56) Their argument calls for full consideration of low probability, high-cost climate damage scenarios in cost-benefit analyses to more accurately reflect risk. A value of $104 per tonne does not, however, reflect the extreme end of SCC estimates, as some studies have produced values exceeding $1,000 per tonne of carbon emitted.
The interdepartmental working group on SCC also concluded that it is necessary to continually review the above estimates in order to incorporate advances in physical sciences, economic literature, and modelling to ensure the SCC estimates remain current. Environment Canada will continue to collaborate with the federal technical committee and outside experts to review and incorporate as appropriate new research on SCC in the future.
Figure 5: SCC Estimates (2010 Canadian Dollars/tonne)
Based on this estimate, the present value of the incremental GHG emission reductions from the utility sector under the Regulations is estimated to be $5,634 million (Table 15).
7.4.2 Benefits from CAC reductions
Presented below are CAC reductions and the associated health and environmental benefits.
Criteria air contaminant reductions
Criteria air contaminants are a group of air pollutants that include sulphur oxide (SOx), nitrogen oxides (NOx), particulate matter (PM); volatile organic compounds (VOC), carbon monoxide (CO) and ammonia (NH3) and ground-level ozone (O3). These air pollutants are associated with smog formation, acid rain, and a wide range of health outcomes.
The generation of electricity is from coal-fired power plants is a contributor to emissions of CACs in Canada. As a result of the Regulations, the following are the most significant cumulative changes to electricity generation in Canada over the period 2015 to 2035:
- Coal-fired electricity generation is projected to decline by 337 TWh (net of a 38 TWh increase in CCS generation).
- Natural gas generation is projected to increase by 256 TWh.
CAC emissions from electricity generation using natural gas and coal with CCS are significantly lower than coal-fired generation, which results in fewer CAC emissions under the regulatory scenario. The CAC emissions (and resulting changes) are determined using emissions coefficients based on the 2009 National Pollutant Release Inventory (NPRI). The coefficients are determined by dividing a specific emission for 2009 by an economic driver for 2009 (e.g. volume of fuel used or volume of output). The coefficient is then multiplied by future output (volume of fuel used or volume of output) to determine the projected emission levels and resulting changes. (see footnote 57)
Nationally, the Regulations are expected to lead to a reduction in CACs from the electricity sector. Table 16 shows the cumulative changes over 2015 to 2035 (in absolute terms) which correspond to the following changes over time (in percentage terms):
Table 16: Cumulative Changes in CAC Emissions

The geographic distribution of the cumulative changes is shown in Figure 6. The proportional differences between provinces are largely determined by the amount of coal-fired generation displaced, the type of coal that would have been burned, and the type of replacement generation. In general, by far the biggest decline in harmful CACs would occur in Alberta, with the exception of TPM where Saskatchewan would experience the greatest drop in emissions.
Figure 6: Distribution of Cumulative Reductions in CAC Emissions, 2015–2035
Coal mining and natural gas sectors
The change in electricity generation would also impact the emissions from the coal mining and natural gas (distribution and pipeline) sectors. However, the changes in these emissions are significantly smaller than those from the electricity sector. An analysis prepared by Environment Canada indicated these potential emission changes represent less than 1% of the total emissions from the electricity power sector. In addition, since the emission impacts occur in opposite directions (e.g. reductions in emissions from coal mining, increases from natural gas extraction and transportation), the net effect would be even smaller. As a result, these impacts were excluded from the analysis.
Air quality and benefit estimation modelling
To estimate how these emission reductions would impact human health and the environment, Environment Canada began by using A Unified Regional Air-quality Modelling System (AURAMS) model to predict how the emission changes would affect local air quality. This is a fully three-dimensional state-of-the-art numerical model described in peer-reviewed scientific literature. AURAMS combined the information on predicted emission changes, with information on wind speed and direction, temperatures, humidity levels, and existing pollution levels, in order to predict how these emissions changes would impact local air quality.
The AURAMS air quality modelling system was run for two years and four scenarios of anthropogenic emissions representing two different projection years: two scenarios (one for the BAU and the other for the regulatory scenario) were run for the year 2020, and the other two scenarios were run for the year 2030 to provide ambient air concentration of pollutants. The meteorological data used for these four scenarios was for the year 2006 and was generated by Environment Canada’s weather forecast model.
The ambient air concentration results were then used to estimate the incremental health and environmental benefits for those two years using the Air Quality Benefits Assessment Tool (AQBAT) and the Air Quality Valuation Model (AQVM2). However, in order to estimate the benefits for all the years between 2015 and 2035, linear interpolation and extrapolation techniques were used. More specifically, for the 2015–2020 period, benefits were assumed to be null in 2015–2017, as no change in air quality was expected, and interpolated linearly up to the 2020 value. For the 2020–2025 period, benefits were assumed to remain constant at the 2020 level as the air quality was not expected to improve significantly. For the 2025–2030 period, benefits were interpolated linearly between 2025 and 2030 values. Finally, benefits were assumed to remain constant between 2030 and 2035. Whenever the benefits were assumed to remain constant, estimates were adjusted to account for changes in population and base data. Note that this assumption provides conservative estimates for health and environmental benefits as the reductions in CACs are expected to increase over time due to more coal-fired unit retirements.
Health benefits
When addressing impacts of air pollution on human health, the most important air quality improvements are the reductions in ambient PM2.5 and ozone levels. Note that the reductions in ambient PM levels are due in large part to the reduction in precursor pollutants, such as NOx and SOx. Both NOx and SOx interact with the atmosphere in order to create PM. While the primary PM emissions from the electricity sector are important, it is the secondary PM formation resulting from NOx and SOx emissions, which has the greatest human health impact.
Average ambient air quality improvements
The largest improvements in air quality are expected to occur in Alberta, Saskatchewan, and Manitoba (Table 17). This is true for both particulate matter and ozone. For ozone, the air quality improvements are somewhat more spread out, but the Prairies still dominate.
While some areas will certainly experience greater air quality improvements than others, at a provincial level, air quality is expected to improve across almost all provinces. Air quality improvements experienced by typical residents in each province for 2030 are shown in Table 17. The Regulations are not expected to have any noticeable incremental change in concentrations of air pollution in British Columbia, the Northwest Territories, Yukon or Nunavut. For this reason, they are not included in the table.

Improved health outcomes
The human health impacts and resulting socio-economic benefits are highly dependent on population proximity to the source of coal-fired electricity generation emissions. It is the population exposure to changes in air quality, and not simply the absolute changes in PM and ozone levels, which determines the health benefits of the Regulations. For this reason, the areas that experience the largest health benefits, and the areas that experience the largest air quality improvements, are not necessarily the same.
The health benefits covered by the analysis include a wide range of health outcomes linked with air pollution. These range from health outcomes such as asthma episodes and minor breathing difficulties to much more serious impacts such as visits to the emergency room and hospitalization for respiratory or cardiovascular problems. Air pollution also increases the average per capita risk of death. While the changes in individual risk levels are small, these individual risk reductions translate into large social benefits.
Table 18 shows some of the estimated changes in cumulative health outcomes as a result of the Regulations. The table also shows the estimated total present value of the improvement in social welfare, expressed in economic (dollar) terms, for all avoided health impacts over 2015–2035. (see footnote 59) The present value of the health benefits is estimated at $4.2 billion, with the largest benefits in Alberta (65%), followed by Saskatchewan (15%) and Manitoba (9%). The PM2.5 reductions account for more than 69% of the health benefits from the Regulations in 2030, while ozone improvements account for 26%.

The Regulations are not expected to have any noticeable incremental change in concentrations of air pollution in British Columbia, the Northwest Territories, the Yukon or Nunavut. As a result, no incremental health impacts are expected for these regions.
Mercury reductions from the electricity sector
Mercury is a heavy metal that can be released into the environment as a result of human activity (i.e. primarily anthropogenic), including through the combustion of coal. The largest anthropogenic source of mercury emissions in Canada is from electric power generation plants, which represented approximately 30% of emissions in 2007.
Once in the environment, mercury can be converted to various forms. For example, mercury can be transformed into a highly toxic compound called methyl mercury, which can accumulate in living organisms and biomagnify (i.e. increase in concentration) as it moves up the food chain. This is the form of mercury to which humans are most often exposed, primarily through consumption of fish and other seafood.
Human exposure to mercury can result in a number of health effects such as intellectual quotient (IQ) loss, memory loss and even death. Studies have examined the link between exposure to mercury and IQ effects. Neurological damage resulting in impaired prenatal brain development can lead to reduced IQ points, with associated costs for the individual and society stemming from direct and indirect loss of productivity, earnings and education, and well-being.
The Regulations are estimated to result in a cumulative reduction of 6 686 kg of mercury released to the environment over the period 2015–2035 compared to the BAU scenario (Table 19). The majority of these reductions are forecast to occur in Alberta (54%) followed by Saskatchewan (38%) and Nova Scotia (8%).
Several studies in the economic literature have estimated and monetized the socio-economic value of mercury-related health impacts. Rice and Hammit (2005) estimated the value of health benefits from proposed caps on mercury emissions from U.S. power plants. With respect to the impacts of mercury on brain development, Rice and Hammit estimated that IQ impacts had a value of $10,000 to $11,000 per kg of emissions, assuming that there is no lower threshold for impacts from exposure. If a non-zero threshold of impacts is assumed, then Rice and Hammit estimate the value of impacts to be lower at $3,900 to $4,500 per kg (in 2000 U.S. dollars).
More recently, Spadaro and Rabl (2008) estimated the global impacts of global mercury emissions on brain development. Because of their global focus, Spadaro and Rabl estimated a much lower value of health impacts per kg of mercury emissions. However, when applying the same methodology used in their study to U.S. data, they came up with results that were nearly identical to the results of Rice and Hammit.
Given the similar results in both of these studies and in the absence of primary Canadian research, the results from Rice and Hammit were adopted for use in this analysis. (see footnote 63)
To be conservative, the low value of US$3,900 per kg of emissions is used for the analysis. Adjusting the value of $3,900 in 2000 U.S. dollars gives a value of $5,880 in 2010 Canadian dollars. Applying this value to measure the benefits of the 6 686 kg of mercury expected to be reduced under the Regulations gives a present value of $24 million (Table 19).

Note that the discussion and the values estimated above apply only to the neurological impacts of mercury exposure and the resulting impacts on IQ. There is emerging scientific evidence that mercury is also a factor in heart disease and the risk of premature death. The inclusion of a potential heart disease and mortality linked to mercury would result in a significant increase in the estimated benefits of the mercury reductions. For example, when Rice and Hammit (2005) include heart disease and mortality risks in their analysis, they find the value of health benefits from mercury reductions increases nearly 50 times, to over $180,000 per kg. Due to uncertainty in the quantification of these impacts, they have not been included in this analysis. However, given the omission of these potentially significant impacts, the benefit estimate should be seen as a low-end estimate of the value of potential health impacts from mercury.
Lead reductions from electricity sector
In terms of health impacts, the developmental neurotoxicity endpoint that has been most studied and for which there is the greatest weight of evidence of a causal relationship is the adverse consequence of early life lead exposure (children under the age of six) on psychometric tests of intelligence (IQ)among school-aged children.
When lead exposure affects IQ, it translates into foregone future earnings/productivity as affected individuals cannot work to their full potential at their usual employment when they reach adulthood.
Studies have shown that some effects of chronic lead exposure may also occur in adulthood. Coronary heart disease, hypertension and strokes are among the main adult human health endpoints that have been quantified in previous economic analyses.
Although some health benefits are expected, they were not estimated due to data limitations.
Environmental benefits
The reductions in CAC emissions from the Regulations will also result in environmental benefits. These have been estimated mainly using Environment Canada’s Air Quality Valuation Model (AQVM2), (see footnote 66) and supplemented with other environmental estimates in an attempt to incorporate benefits not addressed by AQVM2.
Estimate for soiling, visibility and agriculture
The ambient air quality was modelled for years 2020 and 2030 only. In order to generate annual estimates of benefits, different assumptions were applied depending on the expected trend in ambient air quality during a specific time period as discussed above. Over 2015 to 2035, the total present value of benefits estimated with AQVM2 is estimated at $149.9 million. Additional benefits, worth $11.5 million, are estimated using a benefit transfer approach. Therefore, the environmental benefits resulting from CAC emission reductions for Canada are estimated to be approximately $161.4 million. The benefit estimates resulting from the AQVM2 model are shown in Table 20 and discussed below. The environmental impacts due to the Regulations were considered to be negligible for the province of British Columbia and the territories. Therefore, these estimates were excluded from the table and the Canadian total.

Reduced soiling
Soiling from increased deposition of PM results in cleaning expenditures for Canadian households. The Soiling Cleaning Savings Impacts Estimator (SCSIE) model estimates the avoided cleaning costs for Canadian households associated with different levels of PM10. Over 2015 and 2035, the present value of avoided cleaning costs is expected to be $11.2 million. This estimate may be regarded as conservative as it is limited to the residential sector and does not account for cleaning expenditures in the commercial and institutional sectors. The two provinces with the highest reductions in coal-fired electricity generation, Alberta and Saskatchewan, also exhibit the largest gains from reduced soiling.
Improved visibility
All else being constant, visibility increases as ambient concentrations of particulate matter decrease. Based on willingness to pay for improved visual range, the VIEW R2 (Visibility Impacts Estimator of Welfare for Residents) model estimates the monetary change in welfare for different levels of deciviews. (see footnote 67) The present value of welfare gains from improved visibility in the residential sector are expected to be $46.9 million, with Alberta and Saskatchewan combining 74% of total benefits.
Increased agriculture productivity
The Regulations are expected to result in decreased ambient concentrations of tropospheric ozone. Based on exposure-response functions for 20 different crops, the Value of Ozone Impacts on Canadian Crops Estimator (VOICCE) model provides the change in production (tonnes) and total value of crops per Census Agricultural Region due to changes in levels of ozone. National benefits from increased agricultural productivity, expressed in present value, are expected to be $91.9 million. (see footnote 68) Saskatchewan receives about 37% of the national benefits, while Alberta receives more than half.
Additional estimations for timber harvest, recreational use of forests, and material maintenance costs
To address additional environmental benefits that are not considered in AQVM2, a benefit transfer approach was developed to assess the economic impacts of NOx on timber harvests and recreational use of forest ecosystems, and SO2 on material maintenance costs. The mean marginal damages per tonne estimates derived from Muller and Mendelsohn (see footnote 69) were multiplied by the national annual reductions in NOx and SOx emissions. The present value of the benefits associated with these emission reductions is about $11.5 million for Canada.
Other environmental benefits
Overall, the present value of the environmental benefits is expected to be $161.4 million. This impact may be regarded as conservative since many environmental benefits remain non-quantified due to data or methodological limitations. Amongst these benefits are the omitted benefits of reduced soiling to the industrial and commercial sectors, additional recreational benefits of visibility improvement, the beneficial impact of reduced mercury and acid deposition on ecosystems (e.g. on water or forests), and the benefits of lower levels of PM2.5 and ozone on livestock and wildlife premature mortalities and illnesses.
7.4.3 Oil extraction from enhanced oil recovery
One of the benefits of the Regulations is the ability to use the CO2 captured from CCS plants for EOR. EOR is a process in which CO2 is injected into existing oil reservoirs to extract more oil. For the central case, oil has been valued at the forecasted price of WTI from E3MC, and it has been assumed that the use of one tonne of CO2 for EOR results in three incremental barrels of oil production. The present value of the benefits from incremental oil production due to the Regulations is estimated to be $6,098 million over the 2015–2035 timeline.
7.5 Cost-benefit statement
The results of the cost-benefit analysis are summarized in Table 21. Each key variable is presented in the net present values, both in five-year increments as well as the total over the entire study period. The values have been discounted at 3% and are categorized into terms of quantified and monetized costs (generation, increased imports, reduced exports, government) and quantified and monetized benefits (avoided generation costs, environmental benefits and health benefits). The values shown for new capital and refurbishment are net of their residual value to ensure only the part of their costs and benefits amortized within the study period were included. The NPV measures the net benefits (benefits minus costs), for all years indicated.
The NPV of the Regulations in 2015 over the study period is estimated at $7.3 billion. The present value of benefits is estimated at $23.3 billion, largely due to the avoided SCC of carbon ($5.6 billion), avoided generation costs ($7.2 billion), health benefits from reduced smog exposure ($4.2 billion), and additional oil extracted through enhanced oil recovery ($6.1 billion).
The present value of costs is estimated at $16.1 billion, largely due to incremental purchase of natural gas fuel ($8.0 billion), reduced electricity exports and new capital costs ($0.3 billion and $1.9 billion respectively).

The table below reports some corresponding key summary metrics for the cost-benefit analysis. The socio-economic cost per tonne of GHG shows that the non-GHG benefits exceed the costs. (see footnote 70) The benefits of the Regulations are estimated to be 45% greater than the cost.

7.6 Sensitivity analysis
7.6.1 Univariate sensitivity
A sensitivity analysis was conducted on key variables to test the impacts of uncertainty on the results. This requires changing one variable at a time (while holding all other variables/impacts constant). The sensitivity analysis (presented in table 23) shows that the results are robust in terms of demonstrating a positive net present value for the Regulations across a broad range of plausible values for variables and assumptions. The results were most sensitive to varying the discount rate, using the avoided SCC at the 95th percentile estimate, the assumption around the amount of CO2 sold for EOR, and changes in the oil price forecasts.

7.6.2 Scenario analysis
Scenario analysis was also undertaken using Environment Canada’s E3MC model. As the E3MC model is dynamic in nature, a change in one parameter will have impacts on several variables. While the natural gas price was the focal point of the sensitivity analysis, varying the natural gas price influenced economic growth and consumer electricity demand.
Natural gas price sensitivity
Many of the events that shape energy markets cannot be anticipated. Projected energy prices are subject to uncertainty, and are most appropriately analyzed as a range of plausible outcomes. To get a sense of the sensitivity of consumer price impacts to future natural gas prices, these impacts were calculated under a series of alternative assumptions about the future price of natural gas at Henry Hub (Figure 7).
Figure 7: Sensitivity Range of Natural Gas Prices at Henry Hub
The reference price scenario, developed by the National Energy Board, was designed to incorporate the best available information about energy demand and supply into the future. The projections also reflect assumptions regarding pipeline expansions (e.g. Mackenzie and the Alaska pipelines) as well as potential evolutions in natural gas supply and demand in the United States. Under the reference scenario, the natural gas price is projected to increase from about $4.37/MCF (in real 2010 U.S. dollars) to about $8/MCF by 2035. Under the alternative scenarios, the natural gas price in 2035 is expected to be some $7.75/MCF in the low scenario; and some $10.50/MCF in the high scenario. As noted in section 7.2.2, these projections on the future price of natural gas are considered conservative.
As shown in Table 24, variations in the projected price of natural gas at Henry Hub have an impact on the expected prices for natural gas powered electricity generation. These in turn will affect consumer electricity prices in varying proportions across Canada depending on factors such as the overall mix of generating sources in the region’s electricity portfolio.
In Alberta, electricity generator natural gas prices could be as low as $6.05/thousand cubic feet (Mcf) or as high as $9.95/Mcf under the range of sensitivity cases in 2035. These prices are relatively low compared to other Canadian provinces. For example, electricity generator natural gas prices could reach as high as $14.07/Mcf, or fall only as low as $10.18/Mcf in Nova Scotia where prices are expected to be the highest across the selected provinces.

The alternative natural gas price has an impact on the cost of power. Table 25 illustrates the impact of alternative natural gas prices on the cost of producing electricity from combined cycle natural gas units. In Alberta, the cost of power for natural gas combined cycle units in 2035 could be as low as 8.77¢/kWh in 2035 or as high as 11.39¢/kWh under the range of sensitivity cases. These prices are relatively low compared to other Canadian provinces. For example, cost of power for natural gas combined cycle units could reach as high as 13.99¢/kWh, or fall only as low as 11.42¢/kWh in Nova Scotia where prices are expected to be the highest across the selected provinces.

As previously noted, the E3MC model is dynamic in nature and a change in price will influence economic growth and consumer demand. As illustrated in Table 26, the lower natural gas price results in a higher average annual growth rate relative to the reference case, while the higher natural gas prices results in a lower average annual growth rate relative to the reference case. In Alberta, the average annual growth rate for the 2010 to 2035 period is 2.85% with a low natural gas price compared to 2.83% under the reference price and 2.79% with the high natural gas price.

There are many factors that contribute to the formation of consumer electricity prices (e.g. market structure, unit dispatch order and supply/demand conditions), including alternative natural gas prices. These factors have different influences depending on the structure of the electricity market. For example, in Alberta, supply/demand factors and the contribution of natural gas-fired generation to meeting hourly demand tend to outweigh the simple contribution of the natural gas price.
Table 27 illustrates the impact of alternative natural gas prices on average electricity prices. In Alberta, the average electricity price in 2035 could be as low as 18.16¢/kWh or as high as 18.67¢/kWh under the range of sensitivity cases. (see footnote 71) Saskatchewan varies between 20.13¢/kWh and 21.55¢/kWh while Nova Scotia varies from 22.36¢/kWh to 23.40¢/kWh.

7.7 Distributional and competitiveness analysis
7.7.1 Coal sector
The Regulations are expected to affect employment in terms of the closure of coal-fired electricity generating facilities and coal mining facilities. However, employment impacts vary significantly across Canada. As Saskatchewan’s response to the Regulations is to retrofit their coal units with CCS technology, employment impacts are expected to be minimal as the province continues to use its coal resource for electricity generation. Similar impacts are expected in Nova Scotia and New Brunswick as they are dependent on imports of coal for electricity generation.
In Alberta, some employment impacts are expected to occur as 10 coal-fired electricity generating facilities are expected to shut down over the 2015–2035 period. The coal produced in Alberta is unlikely to be demanded in export markets and therefore it is anticipated that the associated production of coal would cease. Furthermore, there are certain regions which are heavily dependent on coal-fired electricity generating facilities and coal mining for direct employment and the indirect jobs associated with the facilities and mines. While employment at natural gas-fired facilities would offset some of the resulting employment losses, natural gas facilities would require fewer employees to operate than coal-fired facilities and associated coal mines.
The employment impacts are considered to be transitional as the unemployed are expected to eventually find new jobs within the economy. For instance, the Alberta government (Alberta Employment and Immigration) has recently estimated that by 2019 there will be a cumulative shortage of 77 000 workers in the province, while the first coal-fired electricity generating facilities projected to shut down in Alberta due to the Regulations are not expected to close until 2020. In sum, transition costs are expected to be minimal or moderate.
It is also important to note that the Regulations could spur innovation in the electricity sector and other sectors of the economy. For example, the costs of adopting CCS technology over time could diminish due to “learning by doing,” which could benefit other sectors of the economy that are able to adopt the technology. The Regulations could also drive demand for clean technologies, energy efficiency and renewable energy. Induced technological change could contribute to reducing further GHG emissions while producing economic co-benefits such as new job opportunities in the clean technology sector, and new skills and technologies that could support Canadian firms in a growing global market for clean technologies.
7.7.2 Natural gas sector
The North American gas market is a highly competitive market, in which natural gas can be bought from many supply sources and delivered to any market centre through an extensive North American pipeline grid. The price of gas is set by market fundamentals such as industrial demand, production levels of gas, and high levels of natural gas in storage. Given this highly competitive market, the price of gas in one region generally differs from the price in another region only by the cost of transportation.
In 2035, the total volume of natural gas used to generate electricity would increase by approximately 40%, or by 292 petajoules (PJ) relative to the BAU.
For the CGI analysis, Environment Canada commissioned a report from Ziff Energy on the expected impacts of the proposed Regulations on the natural gas markets and prices. The report confirmed that the increased gas demand due to the proposed Regulations would not have a material impact on the functioning of the North American gas markets. More specifically, the increased demand would account for less than 1% of the overall North American market. The average yearly price impact would be less than $0.01/MMBtu over the period considered.
Given that the impact on natural gas demand under the Regulations is still below 1% of the overall North American market, it is expected that these conclusions will continue to hold.
One of the concerns identified by stakeholders relates to the impact of the Regulations on the price of natural gas and more specifically on natural gas intensive sectors. The sectors most sensitive to changes in gas prices include
- Fertilizer manufacturers (approximately 85% of input cost is natural gas);
- Chemicals sector who use gas as both a feedstock and a process fuel, which is significant in terms of overall costs;
- Pulp and paper sector for which Industry Canada estimates energy accounts for 15% of overall costs. Additionally, the U.S. Energy Information Association (EIA) estimates 50% of this sector’s energy requirements are self-generated by utilizing wood residues and by-products (black liquor).
As noted above, the study by Ziff Energy indicated that the impact of the proposed Regulations on gas prices would not be material. Therefore, the sectors above are not expected to be affected by natural gas price increases under the Regulations.
7.7.3 Residential and industrial consumers
Residential consumers
Provincial electricity prices are expected to increase in the future with or without the performance standard. In Alberta, price increases in the BAU reflect a shift toward natural gas playing a larger role in setting the hourly price in the Alberta wholesale market. The performance standard will accelerate this shift somewhat. The phase-in of the performance standard is such that any impact on prices is deferred until well out into the future. Over time, the performance standard is expected to have the greatest impacts on electricity prices in Alberta, Saskatchewan, and Nova Scotia. The estimated impact on prices in these provinces is presented below. Note that changes are expected to be small for other provinces and, consequently, they are not included in the table below.

It is expected that the price increases from the Regulations will be passed on to consumers in proportion to their consumption. Allocating the prices in Table 28 to the 2007 residential customer using average consumption (Nova Scotia uses 10 380 kWh, Saskatchewan uses 9 850 kWh, and Alberta uses 5 810 kWh), gives the following estimated average monthly increases in each of the provinces from 2015 to 2035:
- Alberta — $7.80
- Nova Scotia — $6.60
- Saskatchewan — $6.05
Households that consume more (or less) than the average would pay proportionately more (or less) of the total costs.
While households could experience higher electricity cost, the share of household electricity costs relative to disposable income is expected to remain relatively constant. The share remains relatively flat over the 2015–2035 period of the performance standard analysis for all three of the affected provinces.

The incremental price increases as presented in Table 30 are not expected to have major impacts on the industrial sector in Canada. In general, Canada has low electricity rates relative to many of its global competitors including the United States, mainly due to Canada’s natural resources, such as inexpensive hydro (i.e. water resources), and the industrial sector continues to use less energy for each unit of economic output. The long-term trend (from 1990) indicates that the amount of energy used by industry for each unit of economic output (energy intensity) dropped from 12.3 megajoules (MJ)/$ output to 10.7 MJ/$ output. (see footnote 73) It should also be noted that the U.S. EPA is moving forward with its own electricity performance standard which covers new power plants, as well as stringent new air pollution requirements, which should also have a comparative impact on electricity rates in that country.
8. Small business lens
As the regulated community consists of medium and large businesses, the small business lens does not apply to these Regulations.
9. “One-for-One” Rule
The federal government has implemented a “One-for-One” Rule to reduce administrative burden (i.e. the time and resources spent by business to show compliance with government regulations). The “One-for-One” Rule requires that regulatory changes that increase administrative burden need to be offset with equal administrative burden reductions.
These Regulations include a number of mandatory administrative requirements, such as registration, quantification and reporting, as well as requirements for a variety of flexibility mechanisms where regulatees can choose to use or not use any of these provisions. However, once a regulatee chooses to participate in a flexibility mechanism, there are mandatory requirements for participation.
These Regulations were developed with consideration of what industry already does as a way to minimize administrative burden associated with implementation. The regulated community reports the same or similar types of information to other programs and commitments, including Environment Canada’s Greenhouse Gas Reporting Program, Statistics Canada, and various provincial programs and electricity system operators. As a result, minimal incremental administrative burden is expected for emissions and electricity quantification beyond the current activities of regulatees.
There will be incremental administrative burden associated with the applications and reports for the use of the flexibility mechanisms, such as the carbon capture and storage deferral, that are unique to these Regulations. This administrative burden is, for the most part, experienced by units that continue operating and meet the performance standard. Units that close prior to meeting the performance standard will have negligible additional administrative burden.
The “One for One” Rule will be applied to the Regulations as they are expected to result in an annualized cost of $7,000 for all businesses ($350 per business) within the regulatory community.
10. Consultation
Consultations after the publication of the proposed Regulations in the Canada Gazette, Part Ⅰ
Over the past 20 months, Environment Canada has met with 23 stakeholders about 60 times and an additional 25 times with affected provinces. This includes consultations with the coal-fired electricity sector and with representatives from the governments of Alberta, Saskatchewan, Manitoba, Ontario, Nova Scotia, and New Brunswick — the provinces most reliant on coal-fired generation — as well as non-governmental organizations (NGOs). Other federal departments have also consulted with affected stakeholders.
On August 27, 2011, the Government of Canada published the proposed Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations. Upon publication of the proposed Regulations, a 60-day consultation period was initiated, allowing stakeholders and interested parties an opportunity to submit formal comments for consideration.
The Department also held several larger consultation sessions, including face-to-face and webinar consultations. Provincial governments, industry, NGOs and aboriginal groups were invited to participate in these sessions. These sessions provided further detail and discussion on the proposed Regulations and gave stakeholders an opportunity to explore issues of concern or clarification. These sessions were held during the 60-day consultation period in order to facilitate or aid their development of comments for formal submission.
Over 5 000 submissions were received during the 60-day consultation period, including submissions from 4 provincial governments, 16 electricity industry corporations or system operators, 17 other industry corporations or associations, and 6 NGOs. The remainder of comments came from the general public, primarily through the use of form letters available on various Web sites. Based on these comments, and subsequent discussions with industry and provinces, certain refinements have been implemented for these Regulations. These refinements will provide some greater flexibility to industry, while respecting the CGI regulatory framework and maintaining the contribution of the Regulations to Canada’s Copenhagen target.
Extensive bilateral consultations were also held with officials from the governments of Alberta, Nova Scotia and Saskatchewan and with officials from key generating companies (e.g. SaskPower, Nova Scotia Power Inc., Manitoba Hydro) focused on reviewing key technical parameters used in support of this analysis. These consultations focused on parameters ranging from heat rates and emission intensity for various generating units to alternative capital costs for new generating units.
Overall, industry stakeholders and provinces have expressed support for Canada’s commitment to reduce greenhouse gases and, in many cases, for the proposed regulated performance standard approach. There were, however, some firm questions or concerns regarding the sector-by-sector approach and how the proposed Regulations would affect specific units or align with existing provincial regulatory programs. Among the NGOs consulted, some had questions regarding the level of performance standard, exclusion of biomass, CO2 emissions and the application of CCS provisions. In terms of consulted user groups, questions were raised about the secondary impact on natural gas production and electricity prices. The following summarizes key issues raised by stakeholders throughout consultations how they are addressed in the final Regulations.
In considering possible refinements to the proposed Regulations to reflect comments received, Environment Canada was guided by the objectives set out in section 4, the importance of preserving emission reductions in 2020 so as to contribute to Canada’s Copenhagen target, and the importance of respecting the originally proposed regulatory framework.
The following sections provide a summary of the comments received from industry stakeholders, provinces and interested parties. The comments are organized into two sections: policy related and economics related.
10.1 Policy-related comments
Comment #1: Level of performance standard
There was convergence among stakeholders and provinces that natural gas combined cycle (NGCC) units operating in Canada cannot generally achieve an emission rate of 375 tonnes of CO2/GWh. The majority were supportive of a performance standard of 420 tonnes of CO2/GWh. However, some suggested as high as 500 or 550 tonnes/GWh while others suggested an approach where the performance standard level is phased in with the stringency increasing over time as technology matures. Alternatively, environmental non-governmental organizations (ENGOs) offered comments that ranged from upholding the 375 tonnes of CO2/GWh benchmark to tightening the performance standard.
Response #1: The Regulations raise the performance standard to 420 tonnes of CO2/GWh. This level more closely reflects the reasonably expected performance of a base-load natural gas combined cycle unit and responds directly to near-unanimous comments from industry, but is still within the range (360–420 tonnes of CO2/GWh) that was announced in June of 2010. It is also consistent with recent permits issued in the United States.
Comment #2: Definition of old or end of useful life unit
The proposed Regulations included a 45-year useful life period, as well as accommodation for units that are already party to a power purchase agreement or that began operation but switched to burn coal at a later date.
Some industry and provincial governments raised concerns regarding the proposed definition for the end of useful life and its effect on managing price impacts, and the risk of stranded investment and value. In particular, stakeholders felt that the useful life definition should be longer than the 45 years stated in the proposed Regulations. Many commented that it should be increased to 50 years, with some suggestions of it being longer yet, or of a phased-in approach to 50 years and determination on a unit case-by-case basis. The need to consider major capital investments and/or refurbishments as part of the useful life definition was also mentioned by some provincial and industry stakeholders, as well as additional flexibility for units that retire in or before 2020.
Alternatively, the general public and ENGOs requested that the definition of useful life be shortened, so that units would be phased out by 2025 or 2030, at the latest, in order to expedite the process of addressing climate change.
With respect to power purchase arrangements (PPAs), a couple of stakeholders expressed concern that, upon entering the PPA, they were expecting to be able to operate the unit in a competitive market for some years after the expiry of the PPA and generate additional profits. The proposed Regulations would limit or take away that ability. An industry stakeholder also raised concerns about the PPA approach published in CGI with respect to the circumstances of their specific unit.
Specific stakeholders also expressed concern about having a unit that started operation as an oil-fired unit, but then was re-commissioned to burn coal. They contend that the 45 years of useful life calculation should commence when the unit began burning coal instead of the date when the unit initially began operation.
Response #2: To further accommodate concerns regarding stranded value and to further moderate price impacts on consumers, the Government of Canada will establish a 50-year end of useful life definition that will be phased in over three stages. The three stages and accompanying end-of-life in each will be:
- 50 years or the end of 2019 for units built before 1975;
- 50 years or the end of 2029 for units built after 1974 but before 1986; and
- 50 years thereafter.
This change provides more time to some of the earliest units to be affected to moderate price impacts and reduce stranded value, while at the same time respecting Canada’s 2020 emission reduction target.
The Government appreciates the concern to rebase the start date of the unit to when a unit began to use coal as a fuel, but also recognizes that the unit began generating revenue and recovering its capital costs at the time it began operation, not just at the time it began burning coal. As a result, the Regulations will maintain the 18-month life extension for units that converted from oil to coal prior to June 23, 2010.
Comment #3: Carbon capture and storage (CCS) issues
The proposed Regulations included a temporary exemption from the performance standard until 2025 for new and old units that incorporate technology for CCS.
Some provinces and industry stakeholders expressed concerns that the requirements for the CCS temporary exemption were too aggressive, particularly for old units, given the current state of the technology. They advocated that more flexibility was needed in order to reduce the risk of non-compliance and encourage investment in the technology. Suggestions from stakeholders included allowing for project-specific schedules reflecting the learning required for technology development and differences in project deployment schedules, providing two additional years for old units to meet the construction milestones, and subjecting old units to the same requirements as new units.
Comments from NGOs on the CCS temporary exemption varied from eliminating the exemption, to requiring old units that plan to undertake CCS to capture at a higher rate than the 30% identified in the proposed Regulations. They expressed concerns that the CCS temporary exemption could be abused if units close after the end of the exemption period, and that the 30% capture rate for old units receiving the deferral is too permissive.
Some provinces and industry stakeholders raised concerns over the timing and stringency of the application requirements, including, for example, the challenges for a board of directors to unconditionally approve of the construction of the CCS system in advance of the completion of a front-end engineering and design study (FEED study) as well as other related regulatory approvals.
Other industry stakeholders requested additional flexibilities to the requirements, such as a larger margin of error for capital cost estimates in the FEED study or the use of offsets as a way to comply with the 30% capture requirement.
For existing units, some industry and provincial stakeholders claim that their CCS projects will not be economical under the proposed regulatory approach because they were relying on an offset trading market to render their projects economically viable. Furthermore, some units will begin operating before July 1, 2015, and consequently will be able to operate for a significant number of years before the performance standard applies to them at the end of their useful life, leaving no incentive to proceed with CCS.
Some provinces and industry stakeholders have advocated that the 18-month exemption as an incentive for installing CCS technology on existing units is insufficient to provide economic returns for financing CCS projects. They requested broader recognition for emission reductions achieved through the use of CCS as well as increased flexibility as to how this recognition should be implemented in order to allow emission levels to be met in a way that is flexible for energy system management and more fiscally prudent for utilities.
Stakeholder suggestions for broadening recognition included expanding the 18-month exemption to account for ongoing capture at higher rates at existing units and recognizing reductions through CCS that go beyond what is required. A variety of suggestions as to how this recognition should be implemented were provided, including credit or banking instruments that could be used across a company’s fleet or traded among utilities.
One NGO suggested eliminating the 18-month exemption.
Some provinces and industry stakeholders expressed concerns that the CCS flexibilities left units located in areas where the geology is less favourable to implementing CCS at an unfair disadvantage when it comes to compliance options and that the other flexibility provisions (i.e. substitution and standby), which had earlier expiry dates, were being held to an unfair deadline compared to the CCS provisions. Consequently, they argued that the proposed Regulations would favour the ongoing use of coal to generate electricity in some regions in Canada more than others. Suggestions were also noted that biomass should receive comparable treatment as offered by CCS deferrals.
There were also comments from provinces and industry requesting clarity on potential emissions from leakage piping, pumps and storage, and on how assurances related to the transportation and storage of CO2 and their compliance with applicable laws would be provided.
Response #3: The CCS provisions in the final Regulations have been refined to increase the incentives for CCS while at the same time ensuring emission reductions occur. This allows for more time for the deployment of CCS at old units and addresses the majority of concerns raised by provinces and industry.
Specifically, the milestone requirements for old units have been changed to match those for new units. This is because the phased-in useful life results in the majority of old units not requiring the CCS deferral until 2020, at which point the construction milestones for old units would coincide with those for new units. As a result, this change also removes the 30% capture requirement for old units as these units will need to capture at a rate to meet the performance standard within a maximum five years of the start of the deferral. The stringent and regulated construction milestones continue to ensure that units that receive a CCS temporary exemption are taking real steps to implement CCS and meet the performance standard.
For existing units, the Government proposes to provide greater recognition of and incentive for efforts to capture early by increasing the 18-month exemption available for transfer to an old unit to two years.
Flexibility in other provisions has been increased (see other sections), which should ease concerns regarding equity among provisions.
Comment #4: Substitution of units
Industry comments on the substitution provision were generally supportive and included an interest to broaden its application. In particular, it was suggested that the 2020 deadline for this provision be removed so that it remains available, intercompany substitutions be allowed so long as the same level of real reductions are achieved, and that a temporary substitution of an old unit or a standby unit be allowed for when existing units temporarily shut down for a period of time. One stakeholder also suggested that units at a common site (i.e. in the same facility) be permitted to transfer their useful life between them so that they would have a common retirement date. There was also a suggestion from industry to broaden the substitution provision to provide recognition for the early shutdown of units ahead of their end of useful life.
Other stakeholders stated that the substitution provision should be removed entirely because old units should not be allowed to operate past their end of life, and that the provision presented a loophole.
Response #4: This provision has the intention of providing additional flexibility for stakeholders while ensuring emission reductions are maintained. The Government of Canada has expanded the substitution provision in the final Regulations to provide recognition for early permanent shutdown of units before their end of useful life by allowing them to transfer their remaining years to another unit or units. The Government of Canada will also remove the 2020 deadline for the substitution provision.
Comment #5: Coverage of industrial sectors, petroleum coke (petcoke), synthetic gas (syngas) and biomass fuels
Industry stakeholders commented that the proposed Regulations, as drafted, could inadvertently cover industrial sectors that also generate electricity or include industrial activities that are considered beyond the scope of the electricity sector. In particular, concern was expressed that the inclusion of petcoke in the definition of coal could make some industrial sectors subject to these Regulations. Another expressed that these Regulations should not create a disincentive for industry to use fuels, such as through cogeneration processes — fuels that would otherwise be considered waste and flared. It was also commented that these Regulations should not cover “upstream” fuel manufacturing, processing or transportation, as would be the case for including emissions from gasification of coal for synfuel production.
One stakeholder supported the intention of these regulations to cover coal, coal derivatives (e.g. syngas) and petroleum coke, whereas another suggested that the Regulations should cover petroleum coke only if petroleum coke is blended with coal or as a stand-alone fuel. It was also argued that petcoke is a low cost fuel and so including it in the definition of coal as part of these final Regulations would result in the abandonment of its use and subsequent higher energy costs and burden to ratepayers.
Response #5: The Government of Canada agrees that the intention of these Regulations is to address emissions of CO2 specifically from the electricity sector and has taken steps to ensure that the Regulations will not apply to industrial sectors that do not generate electricity for retail sale.
With regard to petroleum coke, the combustion of this fuel source emits more GHG emissions and more sulphur dioxide emissions than coal. Allowing the unregulated use of such a fuel would work at counter-purposes to the Regulations. For this reason, the definition of coal continues to include petroleum coke.
Emissions from the production of synthetic gas (syngas) from coal gasification will continue to be covered so long as the gasification system and the coal-fired electricity unit have a responsible person in common. The Government of Canada feels that the pre-processing of coal for the purpose of electricity generation for sale is consistent with the general intent of these Regulations.
Synfuel is included in the definition of coal, and so units that combust synfuels for electricity generation for sale will be subject to these Regulations.
Gasification systems that produce synfuels that are not used for the generation of electricity for sale will not be covered by these Regulations.
Comment #6: Standby units and emergency circumstances
The few comments on these provisions were in agreement that the requirement to operate such units at a 7% capacity factor or lower was too restrictive and that the percentage should be raised. They commented that standby units require a higher capacity factor to maintain a stable generation level and to avoid costs to equipment and maintenance that arise from unit cold starts. Suggestions on what the percentage should be included 9%, 15% to 40–50%.
It was also commented that standby units are used infrequently and provide benefit to the system and so there should be no end date on this provision and that these units should be able to participate in the substitution provision and adopt CCS provisions at the end of the standby period.
There was general agreement that further clarification of the emergency circumstances provision was needed. In particular, it was requested that the provision explicitly include consideration of drought and provincial commitments to address electricity system emergencies in other jurisdictions as eligible circumstances. It was also suggested that more precision was needed to limit abuse of this provision, especially if effects of climate change results in greater emergency situations.
Further clarity on who should declare an emergency was identified where the majority of comments, including from industry, provincial entities and NGOs, stated that the final determination of an emergency should be made by each respective provincial government or provincial entity, as opposed to being left to the federal government or being applied for by the regulatees.
Response #6: The standby unit provisions of the proposed Regulations were included as a temporary transition measure and were not seen as a way to maintain coal-fired electricity capacity. The Government of Canada appreciates that standby units can improve the reliability of the electricity grid, particularly while the industry makes the necessary investments. As a result, the Government of Canada has increased the availability of this provision to 2030 relative to 2020, as previously published in CGI; however, after that year, these units will be subject to the performance standard.
Upon consideration of comments received on the allowable capacity factor for standby units, the Government of Canada has increased the capacity factor from 7% to 9% in the final Regulations. It was understood that the 7% limit would allow units to maintain equipment in a state to be able to ramp up the unit while at the same time not being an active contributor to the electricity system. The 9% value is reasonably consistent with this intention and ensures that these units are reserved purely for emergency circumstances. Higher capacity factor limits would change the nature of this provision and allow significant operation of the standby units outside of emergency circumstances.
The Government of Canada reviewed the emergency provision as proposed in CGI and concludes that it already provides sufficient flexibility for appropriate emergency circumstances to be considered eligible, as well as maintains stringency through its requirements, approval process and duration limitations. Emergencies must either arise due to an extraordinary, unforeseen and irresistible event, or be declared by the province as an emergency. The emergency circumstance must result in a disruption or significant risk of disruption of the electricity supply within that province, and the operation of the unit is necessary to mitigate this disruption.
Further clarity of this provision will be provided through guidance documents.
Comment #7
As mentioned earlier, thousands of comments were received from various stakeholder groups. The vast majority of these comments were strongly supportive of the Government of Canada’s intention to take action on climate change, if not to request more stringent action. There were also a number of stakeholders that challenged the validity of climate change and its supporting evidence, and in so doing opposed the need for these final Regulations.
Response #7: The Intergovernmental Panel on Climate Change’s fourth assessment report, Climate Change 2007, concludes that the climate system is clearly warming, and it is very likely that emissions of greenhouse gases (GHGs) from human activities worldwide, primarily from the combustion of fossil fuels, are responsible for most of the observed warming since the mid-20th century.
The Government of Canada inscribed in the Copenhagen Accord an ambitious target of reducing our national GHG emissions by 17% from 2005 levels by 2020 and continues to be committed to take action and achieve this target through a sector-by-sector approach. These Regulations to reduce GHG emissions from the coal-fired electricity sector are a critical component of this approach.
Comment #8: Choice of instrument
Some commenters felt the electricity performance standard was an inappropriate instrument to address greenhouse gas emissions, distributing costs unevenly across the nation and placing the burden on consumers rather than industry.
Response #8: The Government of Canada is moving forward on a climate change plan that involves regulating domestic greenhouse gas emissions on a sector-by-sector basis.
The U.S. EPA is currently developing regulations for specific sources of emissions. Given the integration of our two economies, a similar sector-by-sector regulatory plan will allow Canada to make concrete progress towards meeting our emission reduction objectives.
The sector-by-sector approach considers the circumstances of each sector, and tailors the approach to attain significant greenhouse gas emission reductions while minimizing competitiveness impacts. It will result in real emission reductions, while spurring innovation and maintaining competitiveness.
As detailed above in the regulatory and non-regulatory options considered section of this statement, this regulatory approach is determined to be the most effective instrument to address GHG emissions in the Canadian electricity generation sector.
Comment #9
A number of industry stakeholders requested other flexibilities to allow the electricity industry to develop, refine, and prove the effectiveness of emissions reduction technology such as CCS, as well as provide time to better understand potential impacts of the Regulations. Suggestions included extending the coming into force date, and having the Regulations come into effect in a more gradual fashion through a gradual tightening of the performance standard. A number of comments, including those from industry and provinces, advocated for a “fleet” approach, whereby companies would have greater flexibility in managing their own assets, while maintaining the same GHG reduction policy intent at lower costs. The details or suggestions of how to implement a “fleet” approach varied widely. For example, there were requests for such a regulatory approach to include all large emitters in the economy, or apply only to new and end-of-life units, but not existing ones, or simply receiving recognition for early shut down of units.
Alternatively, one industry stakeholder stated that there is a need for regulatory certainty to guide future investments and advocated that the publication of these Regulations should not be delayed. In addition, the vast majority of the total comments received through the 60-day consultation period were from the general public and they, along with some ENGOs, noted the importance of applying the performance standard immediately or on more aggressive timelines in light of the need to reduce GHG emissions. In particular, comments identified the need to guard against any rush to build coal plants prior to the coming into force date of the performance standard.
Response #9: The Government of Canada will proceed with its intended coming into force date of July 1, 2015, for the performance standard requirements of these Regulations applied on a unit by unit basis. New units built after that date will need to meet the performance standard of 420 tonnes of CO2/GWh.
The July 1, 2015, coming into force date, was announced in June 2010 and was maintained in the CGI publication. It was selected to provide predictable and sufficient lead time for industry to respond to the new regulatory requirements of these Regulations and take advantage of anticipated capital stock turnover cycles in order to not strand existing capital, while at the same time moving forward with the Government of Canada’s commitment to reduce GHGs. Continuing with the July 1, 2015, date maintains a balance between comments that requested to either expedite or delay the coming into force date of these Regulations.
The federal government has made the decision to follow a sector-by-sector regulatory approach accomplished through, in the case of coal-fired electricity, an output-based performance standard.
With that said, elements in these Regulations, as well as refinements made based on comments received, go a long way towards incorporating provisions that allow corporations to better manage their coal-fired assets. Specifically,
- the substitution (swapping) provision allows for recognition of early compliance with the performance standard;
- the new provision providing recognition for early shut of a unit allows for transfer of years of operation between units of a similar size; and
- the recognition for installing CCS early (i.e. in advance of being subject to the performance standard) in the form of a deferral that can be transferred to another unit has been increased from 18 months to 2 years.
Comment #10
A number of industry stakeholders commented that the quantification sections of the proposed Regulations should be removed and referenced as a separate guidance document. Their argument is that future amendments would be more easily made in a guidance document than as amendments to regulations. For example, a couple of industry stakeholders noted that the requirements are overly prescriptive and amendments may be needed to respond to advancements in monitoring and measurement practices or technology.
Response #10: The quantification methods are integral to the implementation of the policies within these Regulations and should not be developed separately. It should be recognized that publication of the quantification methods in these Regulations does not prevent the ability to consider advancements in practices or technology. Revisions to the quantification methods, if deemed necessary, can still be made through subsequent amendments to these Regulations. While it is appreciated that revisions to the actual guidance document can be made more easily outside of the regulatory process, these Regulations would likely still need an amendment in order to recognize the revised document version. In addition, making changes to how these Regulations function through the implementation of a formal regulatory process ensures that stakeholders are informed and have an opportunity to participate in that conversation. Therefore, the Government of Canada determined that these sections should continue to be located as a direct part of the regulatory text.
Comment #11
The exclusion of CO2 emissions from biomass from the performance standard was identified as an issue of concern during the comment period. Alternatively, it was stated that the use of municipal solid waste should be recognized because this material would no longer be present in landfills to produce methane gas.
Response #11: The greenhouse gases accounting methodology for the national report inventory is based on the Intergovernmental Panel on Climate Change (IPCC) 2006 guidelines. Within these guidelines, CO2 emissions from biomass combustion are not accounted for because they are assumed to be reabsorbed by vegetation during the next growing season. The proposed and final Regulations are consistent with the IPCC treatment of biomass combustion and provide significant recognition for biomass use.
Municipal solid waste will be recognized as a biomass fuel so long as it meets the definition of biomass as inscribed in these Regulations.
Comment #12
Industry stakeholders requested that criminal penalties as defined under CEPA 1999 be removed for their respective company’s directors and corporate officers in the case of non-compliance. Their rationale was that criminal penalties discourage significant investment decisions on emission reduction activity, such as the decision to implement CCS where there is a small risk that it may not be operational in the required time period. Industry stakeholders are also concerned because electricity generators can be forced by provincial system operators to run in order to maintain system reliability, resulting in non-compliance.
Response #12: These Regulations are being implemented through CEPA 1999 and so are subject to the penalty provisions therein. For this reason the penalties in CEPA 1999 will apply as set forth in the Act.
In addition, the Government of Canada, through consultation with stakeholders and provinces, has considered specific comments and refined the regulatory provisions which should address some concerns and reduce the potential of non-compliance while maintaining the environmental objective of GHG emission reductions. These Regulations also contain provisions to recognize and accommodate emergency circumstances where units will need to operate outside of the performance standard for a limited time in order to address disruptions to system reliability.
Comment #13
Stakeholders and provinces also provided a number of comments related to improving the clarity of regulatory provisions and intent and function as well as administrative edits.
Response #13: These comments did not impact the general policy intent like those identified in the above discussion and were duly considered in the preparation of the Regulations.
Comment #14: Comments on related policy areas
Some comments were received and touched on areas that, while related to the proposed Regulations, were not specific to the proposal.
Stakeholders reiterated early comments that it would be desirable for the federal government to provide clarity as soon as possible regarding the regulatory requirements for new natural gas-fired units.
Industry stakeholders were concerned about the precedent the performance standard for coal-fired generation would set for possible future regulations on GHG emissions from natural gas-fired electricity generation. In addition, some expressed concern that a single performance standard may not be applicable to all types of natural gas facilities.
Industry stakeholders commented that there was a need for a coordinated approach as the government implements its sector-by-sector plan, in order to ensure fairness and equity. In addition, GHG regulations should be aligned with any requirements to address air pollutants from this sector.
Response #14: The Government of Canada’s current focus is to develop the performance standard for coal-fired units. These comments, however, have been and will be taken into account as the Government of Canada moves forward with the sector-by-sector approach.
All regulations for the electricity sector, whether for GHG or air pollutants, will continue to be developed in a coordinated and aligned fashion.
Comment #15: Equivalency agreements
Some provinces and industries have expressed their desire for equivalency agreements pursuant to which the federal regulation would not apply in a particular province. Their rationale is that some provincial regulations provide equivalent or greater GHG reductions, potentially at lesser cost than the federal regulations, and that the agreement would help avoid regulatory duplication.
Non-governmental organizations also expressed support for the use of equivalency agreements but stressed the importance for equivalent or greater GHG reductions from provincial regulations. In addition, the federal regulations are to remain as a backstop, and would start applying in the event of termination of the agreement.
Response #15: Equivalency agreements with a province may be established under CEPA 1999 if there is an enforceable provincial regime that generates equivalent or better environmental outcome, and if the provincial legislation includes provisions similar to section 17 to 20 of CEPA 1999 for the investigation of alleged offences. Equivalency agreements have duration of not more than five years, but may be renewed.
Discussions have been held with some provinces regarding equivalency agreements. In particular, the Government of Canada and the provinces of Nova Scotia and Saskatchewan have announced that they are developing equivalency agreements. The objective is to avoid duplication of effort in controlling GHG emissions, ensure that industry does not face two sets of regulations and allow the province to reduce its emissions in a manner that is appropriate to its particular circumstances.
The Government of Canada will consider entering into agreements with other provinces and territories that desire to do so when the requisite conditions under CEPA 1999 are met.
10.2 Economics-related comments
Extensive consultations with provincial, territorial and industry officials have resulted in significant adjustments to the parameters underlying the estimated business and consumer impacts of the Regulations since the publication of the proposed Regulations in CGI. The following comments summarize the comments received and how they were addressed in the analysis of the Regulations.
Comment #16
Following publication in CGI concerns were expressed by some stakeholders on the impact of the Regulations on the price of electricity on consumers in Alberta, and the level of analysis on the cost and availability of natural gas assumed for Nova Scotia.
Response #16: The approach to modelling the Alberta electricity pool pricing dynamics in E3MC has been updated for the CGII analysis based on input from stakeholders. The new methodology resulted in higher price impacts in Alberta than would have been estimated using the methodology for the CGI analysis, with price impacts occurring gradually over time as natural gas plants set the pool price of electricity more often following coal-fired plant retirements. A study by Power Advisory LLC was commissioned which forecasted price impacts which are in the range of those presented in the CGII analysis, although they are somewhat lower. (see footnote 74) This study also helped ensure the new approach for CGII accurately reflected the dynamics of the competitive electricity market in Alberta.
The forecasted cost of natural gas for Nova Scotia was also updated for the CGII analysis. Upon additional analysis based on input from stakeholders, the prices for natural gas delivered to utilities have been increased relative to the forecasted prices underlying the CGI analysis. A study by Ziff Energy Group was commissioned for Environment Canada in order to assess the cost and availability of natural gas in Nova Scotia. (see footnote 75) The assessment concluded that Nova Scotia is expected to have no difficulty meeting natural gas requirements at fair market prices throughout the forecast period, and that the electricity performance standard is expected to have a minimal impact on natural gas prices in Nova Scotia. The assessment noted that due to falling natural gas production in the Maritimes a reversal of the Maritimes and Northeast (M&NE) Pipeline from a net exporter to a net importer of natural gas is expected by 2019, regardless of the Regulations.
Comment #17: HR Milner and the HR Milner 2 expansion
Some commenters expressed interest about why the HR Milner plant was included in the BAU and if the cost-benefit analysis, emissions results, and price impacts of the proposed Regulations were highly sensitive to its inclusion and the HR Milner 2 expansion.
Response #17: The HR Milner plant’s inclusion in the BAU reflects discussion between Environment Canada and Alberta Government officials. Based on these discussions, evidence was provided to support an in-service date for HR Milner occurring between late 2015 and 2018.
The inclusion of the HR Milner plant in the BAU impacts emission reductions under the proposed Regulations. However, if this plant does not generate electricity, natural gas-fired generating units will be built. Therefore, the reductions in the policy scenario will be the difference between HR Milner’s emissions and the emissions coming from natural gas units that are built instead.
Alberta’s electricity market is highly responsive to supply and demand conditions. Therefore, the inclusion or exclusion of the HR Milner expansion may not necessarily have a significant impact on the pool price. Given the assumptions underlying Environment Canada’s analysis of the proposed Regulations for coal-fired generation, the inclusion of the HR Milner expansion is expected to have a minimal impact on consumer prices. If the HR Milner expansion does not proceed, and natural gas-fired generation is brought on-line to service electricity demand, consumer prices will be somewhat higher (in the range of 1.5 to 2 cents per kWh).
Comment #18: Natural gas price forecast
Many commenters raised concerns that the natural gas price forecast used in the cost-benefit analysis was biased downwards, requesting a more thorough sensitivity analysis under a wider range of natural gas prices.
Response #18: The natural gas price forecast used in the analysis of the proposed Regulations was based on the most up-to-date economic data available at the time. Subsequently, the natural gas price forecast has been updated to better reflect current economic conditions. The analysis of the final Regulations uses the natural gas price forecast produced by E3MC, which is based on historical natural gas costs for utilities by province from Statistics Canada, and the projected growth rate of natural gas prices from the National Energy Board. These prices are somewhat higher than the CGI prices (see section 7.2.2). To further expand the natural gas sensitivity analysis, a univariate sensitivity analysis was completed on the cost-benefit analysis of the Regulations. To get a sense of the sensitivity of consumer price impacts to future natural gas prices, these impacts were calculated under a series of alternative assumptions about the future price of natural gas at Henry Hub (section 7.6.1).
Comment #19: Natural gas price response
A commenter commissioned a study by Ziff Energy Group that suggested the standard, as presented in the proposed Regulations, if applied throughout North America, would create substantial upward pressure on natural gas prices.
Response #19: The analysis of the proposed and final Regulations is limited to the incremental impact of the Canadian standard, which, according to a study commissioned by Ziff Energy Group for Environment Canada, would have a negligible impact on North American natural gas prices. The impact of the policy choices of other nations is outside of the scope of the analysis.
Comment #20: Emissions from imported electricity
Numerous commenters stated that the proposed Regulations would simply displace greenhouse gas emissions to other jurisdictions rather than create real reductions, and that this “carbon leakage” is a persistent policy issue inherent to all non-global regulations. Further, the use of a global value for the SCC is inconsistent with an approach which fails to estimate and value emissions created through carbon leakage.
Response #20: In December 2009, the Government of Canada committed to a national greenhouse gas reduction target of 17% below its 2005 levels by 2020, and inscribed this in the Copenhagen Accord. Our 2020 target is aligned with that of the United States.
The U.S. EPA is currently developing regulations for specific sources of emissions. Given the integration of the two economies, a similar sector-by-sector regulatory plan will allow both countries to make concrete progress towards meeting emission reduction objectives. To the extent that both the United States and Canada are moving toward the same objective in tandem, the potential for carbon leakage to occur should be mitigated. Further, even taking into account the small increase in imports of electricity from the United States, overall emissions reductions in Canada remain significant over the study period.
More specifically, the Regulations will phase out high-emitting coal-fired generation and promote a transition towards lower- or non-emitting types of generation such as high-efficiency natural gas, renewable energy, or fossil fuel-fired power with carbon capture and storage. A list of responses to meet the capacity and generation gaps over the 21-year period includes an increase in capacity utilization, construction of new natural gas or coal CCS units, reduced exports, and increased imports. Overall, the Regulations are expected to result in a net reduction of 214 Mt over the period 2015–2035.
Social cost of carbon values are used for the analysis of Canadian regulations to assess the avoided global damages associated with GHG emission reductions brought forth by Canadian actions in order to ensure that the full value of our contribution to the reduction of global damages from climate change is recognized. It would also be challenging to separate out the specific benefit to Canada of an emission reduction in Canada given that climate change is a global environmental issue. The values used for this analysis are based on the approach used by the EPA developed by an interagency working group and world leading experts on the issue.
Comment #21: Perceived issues around the quantification and monetization of health benefits
A commenter stated that the health benefits presented in the analysis of the proposed Regulations were unrealistic and inaccurately monetized benefits associated with other provincial and federal regulations as benefits of the proposed Regulations.
Response #21: All known/existing provincial and federal air regulations have been incorporated into the BAU scenario of the cost-benefit analysis. Therefore, all the CAC reductions and associated health and environmental benefits presented are incremental and attributable to the Regulations. As presented in section 7.2.4, a comprehensive modelling work was conducted using AURAMS, AQVM2, and AQBAT of Health Canada to assess the impacts of CAC reductions on the levels of ambient air concentration and subsequently on health and environment.
Comment #22: Effects of the proposed Regulations on coal-related industries
Multiple commenters voiced concerns with the lack of analysis provided on coal-associated industries such as coal mining. The proposed and final Regulations are expected to decrease the demand for coal in these markets. These commenters contended that this would cause the coal mining industry to shrink, increasing unemployment and causing economic damages that were not monetized in the cost-benefit analysis of the proposed Regulations.
Response #22: The calculation of the NPV in the cost-benefit analysis for the Regulations factors in the impacts of replacing coal-fired generation with natural gas fired generation in terms of costs and avoided costs for electricity generation. Section 8.1 now incorporates a more detailed analysis of the impacts on the coal sector. The conclusion of the analysis was that some transitional unemployment would occur due to the Regulations, but that transitional costs are expected to be minimal/moderate.
Comment #23: Carbon capture and sequestration analysis
Commenters noted that the cost-benefit analysis of the proposed Regulations did not specifically address the costs or benefits of carbon capture and sequestration, how these specific technologies may impact emissions, generation costs, and any resulting secondary economic activities.
Response #23: The cost-benefit analysis for the Regulations now includes impacts from the application of CCS technology to Boundary Dam units 4, 5 and 6. The estimated capital costs of CCS have been incorporated for these units, while CO2 emissions reductions have been valued at the SCC. The analysis also takes into account the downstream impact of the use of CO2 for EOR. In the distributional section it was noted that employment impacts in Saskatchewan’s coal mining sector would be mitigated by keeping coal-fired generation capacity running with the successful application of CCS. Although considered a transfer in cost-benefit analysis, the Government of Saskatchewan would likely collect tax and royalty revenues on the incremental production of oil in this province, which constitutes a portion of the net benefit from CCS/EOR to Canada as a whole.
Comment #24: Inappropriate import prices
A large group of commenters stated that import and export prices as presented in the CGI analysis were neither in line with current nor historical data. They asserted that the import/export prices used in the cost-benefit analysis of the proposed Regulations were significantly underestimated, biasing the cost of the estimated reduction in exports and increase in imports downwards.
Response #24: The price forecasts for imports and exports are calculated within E3MC based on the historical mix and outlook of future mix of short- and long-term electricity export contracts. The price of short- term and long-term electricity contracts vary systematically, thus assumptions on the future contract mix will influence forecasted prices. Imports from the United States are based on the weighted average cost of power from the importing area.
Comment #25: Lifecycle approach to emissions
A commenter noted that a full life cycle approach to emissions analysis would present a complete emissions profile of various fuels. When plant source emissions are considered, analysis is biased towards natural gas; however, the extractions of some types of natural gas produce large environmental impacts. It could be that unconventional natural gas lifetime emissions are greater than the lifetime emissions of traditional coal.
Response #25: The E3MC model is an integrated model that projects emissions for all of the sectors of the economy. While the cost-benefit analysis focuses on the direct impacts of the policy on the electricity sector and consumers, the macroeconomic modelling takes into account the secondary impacts on the economy, also factoring in changes in emissions from other sectors, such as the oil and gas sector. Factoring in all of these impacts, the policy leads to a net reduction in GHG emissions for Canada.
Comment #26: Unit level data
Commenters felt the average capital, and fixed and variable O&M costs reported in the CGI analysis were rather low when compared to AEO estimates.
Response #26: Environment Canada’s modelling framework is parameterized with the most up-to-date publicly available electricity cost and performance characteristics for new generating technologies. In developing these costs and performance characteristics, Environment Canada sought the advice of provinces and territories, electricity generators and the Canadian Electricity Association. The information sought included capital costs, fixed and variable O&M, heat rates and emission intensity for each unit included in Environment Canada’s modelling framework.
Where information was provided by the officials from the provinces/territories, electricity generators and the Canadian Electricity Association, they were included in the model. In the absence of province or generator specific information, the modelling relied on data from the EIA.
For the Annual Energy Outlook 2011 cycle, EIA commissioned an external consultant to develop current cost estimates for utility-scale electric generating plants. This report can be found at www.eia.gov/oiaf/beck_plantcosts/index.html. Site-specific costs for geothermal were provided by the National Energy Renewable Laboratory, “Updated U.S. Geothermal Supply Curve,” February 2010.
Comment #27: BAU and Policy scenario representation
Numerous commenters had concerns with the characterization of the BAU and Policy case as developed within the analysis of the proposed Regulations.
Response #27: The BAU scenario underlying the analysis of the final electricity performance standard for coal-fired generation has been revised to better reflect Alberta’s load growth, and the permanent closure of Sundance units 1 and 2. The import capabilities have also been reviewed.
Environment Canada has been working with provincial and industry stakeholders to incorporate their comments where feasible. Saskatchewan’s load growth has been reviewed along with the infrastructure costs provided by the stakeholders. The refurbishment of Boundary Dam 3 with CCS was included in the BAU because the intent to move forward with this project was established well before the announcement of the policy in CGI. Further CCS refurbishments of coal units in Saskatchewan have also been taken into consideration as per the advice of Saskatchewan officials.
Comment #28: Excess capacity
One of the main comments received on the modelling undertaken in support of the proposed Regulations pertained to the increased utilization of excess capacity. Commenters were critical of the assumption that there was excess capacity to utilize.
Response #28: Environment Canada’s modelling framework is parameterized with Statistics Canada data — publicly available and confidential — and with publicly available company data. For capacity, it is based on Statistics Canada name-plant capacity by unit. Using Statistics Canada’s confidential micro-data, operational characteristics are determined at the unit level (e.g. outage rate). This outage rate is then applied to the name-plant capacity to determine the effective capacity.
Comment #29: Plant builds
Many commenters believed that the plant build schedule included in the modelling for the CGI analysis was unrealistic and inconsistent with current utility expansion plans.
Response #29: Environment Canada aligned new additions with current provincial and utility expansion plans. In a situation where there is a supply-demand imbalance, Environment Canada’s E3MC model endogenously builds new capacity. These endogenous builds follow industry establish rules for bringing on new capacity (e.g. four years for a combined cycle gas turbine, one to two years for wind units).
Comment #30: Trade flow infrastructure
Commenters felt that the trade flows reported in the CGI analysis exceeded the capacity of current transmission lines and that the costs of additional infrastructure were underestimated.
Response #30: Environment Canada’s modelling assumed that no infrastructure would be built to allow a significant increase in electricity trade. The exports/imports reported in CGI are the cumulative total for the period 2015 to 2030. While Environment Canada’s model has the capacity to build interprovincial and international flows, due diligence is undertaken to ensure that provincial plans are fully respected (i.e. the model only builds new transmission that is provided in provincial plans). If new infrastructure is built, then the model will fully cost the building of the new transmission capacity.
Overall
Provisions developed within the Regulations respond to concerns raised through the consultations, but are limited in availability and duration in order to emphasize their use as transitional measures, all the while maintaining environmental objectives and the stringency of the proposed Regulations.
These provisions
- maintain consistency of a national regulatory approach and the focus on emission reductions;
- treat regions and regulatees equitably;
- minimize stranded capital investments; and
- avoid setting an undesirable precedent for other sectors.
11. Regulatory cooperation
These Regulations have been developed with consideration of approaches undertaken by other jurisdictions, mainly Canadian provinces and the United States.
Federal and state-level actions in the United States are setting limits for new fossil fuel-fired electric utility generating units based on a performance standard approach based on parity with natural gas combined-cycle generation. On March 27, 2012, the United States EPA issued proposed New Source Performance Standards (NSPS) for new fossil fuel-fired electric utility generating units (EGUs) including: fossil fuel-fired boilers, integrated gasification combined cycle (IGCC) units and stationary combined cycle turbine units. The rule would act as a base level requirement, whereby any new power plant could emit no more than 454 tonnes of CO2/GWh on a gross output basis. Permits for individual plants could be more stringent. For example, in November 2011, the EPA issued a pre-construction permit under the New Source Review Program for a 590 MW Texas-based natural gas combined cycle electricity generating facility with an annual emission limit of 416 t/GWh. In January 2012, the State of New York proposed to adopt CO2 Performance Standards for Major Electric Generating Facilities, under which boilers, natural gas combined cycle units and gas-fired stationary engines would be subject to a performance standard of 420 t/GWh. These levels support Canada’s choice of 420 t/GWh as the proposed performance standard based on natural gas combined-cycle technology for coal-fired electricity generation.
While U.S. GHG requirements do not address existing coal plants, the EPA has finalized stringent air pollutant requirements for these plants, most notably the Cross-State Air Pollution Rule (CSAPR) and the Mercury and Air Toxics Standards (MATS). Within Canada, the federal government has consulted extensively with provincial governments throughout the development of these Regulations. In particular, the Government of Canada and the province of Nova Scotia have announced that they are developing an equivalency agreement. An equivalency agreement would see the federal regulations stand down and allow the provincial regulation to apply; an agreement is possible where there is an enforceable provincial regime that achieves an equivalent or better environmental outcome than the federal regulation.
An equivalency agreement is appropriate in this case because the estimated outcome on GHG emissions is equivalent, and the agreement allows the province of Nova Scotia to meet the goal in a manner that is appropriate to its particular circumstances. Both governments wish to avoid duplication of effort to control greenhouse gas emissions, and are working together to ensure that industry does not face two sets of regulations.
The Government of Canada will consider entering into agreements with other provinces and territories that desire to do so, provided that the requisite conditions under CEPA 1999 are met. Discussions have also taken place with Saskatchewan.
12. Rationale
The Government of Canada is committed to reducing Canada’s total GHG emissions to 17% below its 2005 levels by 2020 — a target that is inscribed in the Copenhagen Accord and aligned with the United States. In 2010, GHG emissions from the electricity generation sector contributed around 15% (or approximately 101 Mt) to Canada’s inventory of emissions. Coal-based electricity in Canada was responsible for 77 Mt of GHG emissions in Canada representing 77% of total electricity sector emissions.
The Government of Canada’s approach to addressing climate change is based on the principle of maximizing environmental performance improvements while minimizing adverse economic impacts. The regulated performance standard approach provides necessary regulatory certainty for the electricity sector at a time when the sector is facing major capital stock turnover, is administratively simpler than a cap-and-trade system, ensures the phase-in of lower- or non-emitting types of generation and provides more certain economic signals to decision makers considering new or replacement power generation plants. In addition, through consultations, industry and provincial stakeholders, in spite of having specific concerns, have expressed broad support of the regulated performance standard approach.
As a consequence, a cost-benefit analysis was conducted for the selected regulatory instrument, which indicated that it would result in a net reduction of approximately 214 Mt of CO2e of GHG emissions over a period of 21 years. The incremental benefit of achieving these reductions is estimated to be $23.3 billion while the incremental cost is estimated to be $16.1 billion over the same period. This results in a net present value of approximately $7.3 billion.
The Regulations are considered to be an effective and efficient way of fulfilling the Government of Canada’s commitment of reducing Canada’s total GHG emissions.
13. Implementation and enforcement
13.1 Implementation
The regulated community is small and well known and has already been extensively consulted in the development of the Regulations, as well as in previous efforts to regulate GHGs from this sector. As a result, there is a heightened awareness and interest in the forthcoming Regulations on the part of the regulatees.
To meet the objectives of the Regulations, compliance promotion activities targeting owners and operators of coal-fired electricity generators will be delivered to ensure a high level of compliance as early as possible during the regulatory implementation process.
In addition, the earliest regulatees will be required to register under the Regulations will be in 2013, where the requirement to comply with the performance standard will come into effect January 1, 2015. Compliance promotion activities will also be conducted before the coming into effect of these two requirements and as units become subject to the regulatory requirements based on their respective end of useful life date.
Regulatees will be required to submit a performance report with specified required information through an electronic reporting system. Environment Canada will monitor the GHG emission performance of electricity generating units and compliance with the Regulations.
It should also be considered that the number of regulatees needing to comply with the performance standard and reporting requirements increases over time as these requirements are relative to the electricity generating unit’s age. This phasing in of regulatees also facilitates easier implementation of compliance promotion activities and monitoring of compliance.
In the situation where a unit is found to exceed applicable standards, the normal course of events would be to perform an engineering audit as part of an enforcement inspection to determine if an enforcement action should be taken against the owner/ operators of the unit.
13.2 Enforcement
The Regulations are made under CEPA 1999; therefore, enforcement officers will, when verifying compliance with the Regulations, apply the Compliance and Enforcement Policy (see footnote 76) for CEPA 1999. This Policy sets out the range of possible responses to alleged violations, including warnings, directions, environmental protection compliance orders, ticketing, ministerial orders, injunctions, prosecution and environmental protection alternative measures (which are an alternative to a court prosecution after the laying of charges for a CEPA 1999 violation). In addition, the Policy explains when Environment Canada will resort to civil suits by the Crown for cost recovery.
To verify compliance, enforcement officers may carry out an inspection. An inspection may identify an alleged violation, and alleged violations may also be identified by Environment Canada’s technical personnel, through information transmitted to the Department by the Canada Border Services Agency or through complaints received from the public. Whenever a possible violation of the Regulations is identified, enforcement officers may carry out investigations.
When, following an inspection or an investigation, an enforcement officer discovers an alleged violation, the officer will choose the appropriate enforcement action based on the following factors:
- Nature of the alleged violation: This includes consideration of the damage, the intent of the alleged violator, whether it is a repeat violation, and whether an attempt has been made to conceal information or otherwise subvert the objectives and requirements of the Act;
- Effectiveness in achieving the desired result with the alleged violator: The desired result is compliance within the shortest possible time and with no further repetition of the violation. Factors to be considered include the violator’s history of compliance with the Act, willingness to cooperate with enforcement officers, and evidence of corrective action already taken; and
- Consistency: Enforcement officers will consider how similar situations have been handled in determining the measures to be taken to enforce the Act.
13.3 Penalties
Subject to the coming into force of section 72 of the Environmental Enforcement Act, chapter 14, under CEPA 1999, every person who commits an offence is liable, (a) on conviction on indictment, to a fine of not more than $1,000,000 or to imprisonment for a term of not more than three years, or to both; and (b) on summary conviction, to a fine of not more than $300,000 or to imprisonment for a term of not more than six months, or to both.
Where an offence under CEPA 1999 is committed or continued on more than one day, the person who committed the offence is liable to be convicted for a separate offence for each day on which it is committed or continued.
14. Performance measurement and evaluation
The Performance Measurement and Evaluation Plan (PMEP) describes the desired outcomes of the Regulations and establishes indicators to assess the performance of the Regulations in achieving these outcomes. The PMEP package comprises three documents:
- the Performance Measurement and Evaluation Plan, which details the regulatory evaluation process;
- the logic model, which provides a simplified visual walkthrough of the regulatory evaluation process; and
- the table of indicators, which lists clear performance indicators and associated targets, where applicable, in order to track the progress of each outcome of the Regulations.
The three documents complement each other and allow the reader to gain a clear understanding of the outcomes of the Regulations, the performance indicators, as well as the evaluation process.
Outcomes
The PMEP details the suite of outcomes for each unit as they comply with the Regulations. These outcomes include the following:
- Upon publication of the Regulations, the regulated community will become aware of the Regulations and meet the reporting requirements, when applicable (immediate outcome).
- Then, as the performance standard enters into force for a unit of a given vintage, the owner/operator of this unit will meet the performance standard, make use of time-limited flexibility mechanisms, invest in CCS technology, or retire the unit (intermediate outcome).
- In all cases, these cumulative actions will progressively contribute to the final outcomes and intended objective of the Regulations: reducing GHG emissions from coal-fired generation, and decreasing the proportion of electricity generated by high-emitting coal-fired sources (final outcome).
As a key feature of the Regulations, units will become subject to the performance standard requirements as well as to compliance and promotion activities gradually, depending on when they reach their respective end of useful life date. As a result, the outcomes, such as anticipated reductions in GHG emissions, will take place progressively and accumulate over time.
Performance indicators and evaluation
Clear, quantitative indicators and targets, where applicable, were defined for each outcome — immediate, intermediate and final — and will be tracked on a yearly basis. In addition, a compilation assessment will be conducted every five years starting in 2020 to gauge the performance of every indicator against the identified targets. This regular review process will allow the Department to clearly detail the impact of the Regulations on the coal-fired electricity generation sector as more and more units become subject to the regulatory requirements, and to evaluate the performance of the Regulations in reaching the intended targets. The five-year compilation review also respects the expected capital stock turnover timelines for this industry.
These performance indicators are available in the table of indicators, and make direct references to the outcomes listed in the logic model.

The model is intended to describe the formation of tropospheric ozone, particulate matter, and acid deposition in North America in support of policy and decision making.

See Gong et al., 2006; McKeen et al., 2007; Samaali et al., 2009; Smyth et al., 2009.
Footnote 41
The relationship between air pollution emissions and ambient air quality is extremely complicated and non-linear. This is particularly true for the formation of ground level ozone, through the interaction of NOx and VOCs.
Footnote 42
The AQBAT model contains functions representing the relationship between air pollution exposure, and per capita health risks. The model also contains estimates of the social welfare benefit (or socio-economic value) of reducing the risks of different health outcomes. Using the estimated changes in ambient air quality under the Regulations, AQBAT estimated how the per capita risk of health problems would be reduced. Changes in per capita health risks are then multiplied by the appropriate socio-economic value to estimate the benefit of the per capita risk reductions. Both the reduction in per capita risks and the estimated per capita welfare benefits are then multiplied by the exposed population to determine the estimated number of avoided health events and the total economic value of the health benefits, for each census division in Canada. These are then aggregated by census division to calculate provincial and national health impacts and benefits.

Non-emitting = Biomass + geothermal + hydro + landfill gases/waste + nuclear + solar + wave + wind
Footnote 46
Non-emitting = Biomass + geothermal + hydro + landfill gases/waste + nuclear + solar
Footnote 47
Net imports = imports – exports. Increase in net imports means increase in imports and/or decrease in exports.
Footnote 48
Note that totals include all jurisdictions in Canada.
Footnote 49
Under the CBA, generation costs for exports are borne by the generating province.
Footnote 50
This figure represents the gross reductions from the utility sector relative to the BAU. For net reductions after accounting for GHGs, which result from increased extraction of oil and gas, see Table 22.

The value of $26/tonne of CO2 in 2010 (in 2010 Canadian dollars) and its growth rate have been estimated using an arithmetic average of the three models PAGE, FUND, and DICE.

Footnote 56
The value of $104/tonne of CO2 in 2010 (in 2010 Canadian dollars) and its growth rate have been estimated using an arithmetic average of the two models PAGE and DICE. The FUND model has been excluded in this estimate because it does not include low probability, high-cost climate damage.
Footnote 57
The emission factors are based on NPRI 2007, and hence often differ at the unit level. Projected increases in new generation are calibrated to historical national inventory levels.
Footnote 58
The average is the emission levels weighted based on the population of the census regions.
Footnote 59
The health outcomes shown in Table 18 are statistical estimates, based on the overall changes in per capita risks. For example, the AQBAT model predicts that over the period 2015–2035 the Regulations would reduce mortality risks in Manitoba, resulting in an estimated approximately 80 fewer premature deaths in the province. However, this does not mean that there will be 80 specific, identifiable individuals who will be “saved” in Manitoba. Thus, the “health benefits” of the Regulations are not the number of lives “saved” per se, but rather the reduction in the average per capita risk. Similarly, the values in the economic benefit column do not measure the benefit of the individual lives saved, or hospitalizations prevented. Rather, this is the aggregated benefit of the reduction in individual risk levels across the province.

Footnote 62
These totals include other pollutant-related health benefits
Footnote 63
It is understood that there are critical differences in population distribution and mercury exposure between Canada and the United States, and as a result, U.S. values should be taken as rough approximations of Canadian benefits only.

Footnote 66
The benefits assessment by AQVM2 was based on the comparison of a baseline scenario against an alternative policy scenario. The ambient air quality was modelled by AURAMS for each scenario, and the environmental benefits were estimated from the incremental difference between both scenarios.
Footnote 67
The deciview is a visual index designed to be linear with respect to perceived visual air quality changes over its entire range. The deciview scale is zero for pristine conditions and increases as visibility degrades. A change in deciview represents a perceptible change in visual air quality.
Footnote 68
The Census of Agricultural Regions dataset does not cover northern Saskatchewan, Yukon, Nunavut, and the Northwest Territories. Even though little agricultural activity is expected to occur in the three latter regions, the exclusion of northern Saskatchewan may lead to an underestimation of the national benefits, as this province already has about 37% of the total benefits for agriculture. Current agricultural data does not allow an assessment of the magnitude of the underestimation.
Footnote 69
Mean marginal damages (in 2010 dollars/tonne) are calculated as follows: NOx (timber) = $4.85; NO x (recreation) = $2.91; SO2 (material) = $12.30. The cumulative NOx and SOx emission reductions for the 2015–2035 period are respectively 546 kilotonnes and 1 156 kilotonnes.
Footnote 70
The socio-economic cost per tonne ratio is calculated by subtracting the present value of the sum of all non-GHG benefits from the present value of the costs of the Regulations, and then dividing by the present value of the tonnes of CO2.
Footnote 71
In Alberta, producer response and the timing of new generation influence the retail price. The model predicts that the supply generation brought into service over the 2023 to 2025 period creates a surplus in light of the demand conditions. This results in the average electricity price under the high natural gas price scenario being somewhat lower than the reference scenario.
