Regulations Limiting Carbon Dioxide Emissions from Natural Gas-fired Generation of Electricity — 3
New generation of electricity — boiler units 3 (1) These Regulations apply to any boiler unit that has a capacity of 25 MW or more, that begins generating electricity on or after January 1, 2019, beginning on January 1 of the calendar year during which it meets the following conditions: (a) more than 30% of its heat input, on average, during the calendar year, comes from the combustion of natural gas; (b) its heat to electricity ratio is not more than 0.9; and (c) a quantity of the electricity that it generates is sold or distributed to the electric grid. New generation of electricity — combustion engine units (2) These Regulations apply to any combustion engine unit that has a capacity of 25 MW or more, that begins generating electricity on or after January 1, 2021, beginning on January 1 of the calendar year during which it meets the following conditions: (a) more than 30% of its heat input, on average, during the calendar year, comes from the combustion of natural gas; and (b) 33% or more of its potential electrical output is sold or distributed to the electric grid, without regard to the quantity of electricity sold or distributed to the electric grid coming from the unit if the unit is equipped with replacement combustion engines that are temporarily installed, for a period of not more than 90 days, as part of repairs or maintenance, during the replacement period. Existing generation of electricity (3) These Regulations also apply to any unit referred to in subsection (1) or (2) that generated electricity at a facility before January 1, 2019 in the case of a boiler unit and before January 1, 2021 in the case of a combustion engine unit and (a) was moved to another facility on or after whichever of those dates is applicable; or (b) is a combustion engine unit for which more than 50% of the total capacity of the combustion engines comes from combustion engines installed on or after January 1, 2021, unless they are engines that have a capacity of 150 MW or less and are installed to replace engines that have a capacity of 150 MW or less and that are installed before January 1, 2021. Significantly modified — conversion to natural gas (4) These Regulations also apply to any boiler unit referred to in subsection (1) that was registered under subsection 4(1) of the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations , and that generated electricity before January 1, 2019, beginning on January 1 of the calendar year following that in which the unit ceases to combust coal. Hybrid configuration (5) If a combustion engine unit and a boiler unit share the same steam turbine, the provisions of these Regulations apply as follows: (a) with respect to a combustion engine unit, they apply to the assembly comprised of combustion engines and any other equipment connected to them including the steam turbine that it shares with the boiler unit; and (b) with respect to a boiler unit, they apply to the assembly comprised of boilers and any other equipment connected to them including the steam turbine that it shares with the combustion engine unit. Non-application (6) These Regulations do not apply to units with respect to a calendar year in which they generate electricity and, if applicable, produce useful thermal energy from the combustion of coal as defined in subsection 2(1) of the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations .
