Application

Marginal note:New generation of electricity — boiler units

  •  (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.

  • Marginal note: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.

  • Marginal note: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.

  • Marginal note: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.

  • Marginal note: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.

  • Marginal note: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.

Requirements

Emission Intensity Limits

Marginal note:General

  •  (1) A responsible person for a unit must not emit from the unit an amount of CO2 from the combustion of fossil fuels in the unit, that is, during a calendar year, on average, greater than any of the following intensity limits, as applicable:

    • (a) 420 tonnes of CO2 emissions/GWh of energy produced

      • (i) in the case of boiler units, other than those referred to in subsection 3(4), and

      • (ii) in the case of combustion engine units that are equipped with at least one combustion engine that has a capacity of more than 150 MW; and

    • (b) 550 tonnes of CO2 emissions/GWh of energy produced in the case of combustion engine units that are equipped with combustion engines that have a capacity of 150 MW or less.

  • Marginal note:Significantly modified boiler units

    (2) It is prohibited for a responsible person for a boiler unit referred to in subsection 3(4) to emit from the boiler unit an amount of CO2, from the combustion of fossil fuels in the unit, that is, during a calendar year, on average, greater than 420 tonnes of CO2 emissions/GWh of energy produced, as applicable, beginning in

    • (a) the year after the unit’s end of useful life, if the initial performance test conducted under subsection 5(1) indicates a CO2 emissions intensity greater than 600 t/GWh;

    • (b) the sixth year after the unit’s end of useful life, if the initial performance test conducted under subsection 5(1) indicates a CO2 emissions intensity greater than 550 t/GWh and less than or equal to 600 t/GWh;

    • (c) the ninth year after the unit’s end of useful life, if the initial performance test conducted under subsection 5(1) indicates a CO2 emissions intensity greater than 480 t/GWh and less than or equal to 550 t/GWh; or

    • (d) the eleventh year after the unit’s end of useful life, if the initial performance test conducted under subsection 5(1) results in a CO2 emissions intensity less than or equal to 480 t/GWh.

  • Marginal note:Quantification of energy and emissions

    (3) For the purposes of subsections (1) and (2),

    • (a) the quantity of energy produced in the calendar year must be determined in accordance with section 11; and

    • (b) the quantity of CO2 emissions produced in the calendar year must be determined in accordance with sections 12 to 18, as applicable.

  • Marginal note:Special Rules

    (4) For the purposes of subsection (3), if, in the calendar year, one of the combustion engines of the unit is repaired or maintained and one or more replacement combustion engines are temporarily installed, the quantity of energy and CO2 emissions produced during the replacement period, to a maximum of 90 days per calendar year, are excluded from the calculation referred to in that paragraph.

  • Marginal note:Exception — boiler unit

    (5) Despite subsection (1), a boiler unit that, in a calendar year, does not meet one of the conditions set out in subsection 3(1), is not subject to the emission intensity limit for that calendar year.

  • Marginal note:Exception — combustion engine

    (6) Despite subsection (1), a combustion engine unit that, in a calendar year, does not meet one of the conditions set out in subsection 3(2), is not subject to the emission intensity limit for that calendar year.

Performance Tests — Significantly Modified Boiler Units

Marginal note:Initial performance test

  •  (1) An initial performance test must be conducted in the presence of the performance test verifier and in accordance with subsection (3) to determine the CO2 emission intensity for a boiler unit referred to in subsection 3(4) within 12 months following

    • (a) in the case of a unit that has ceased to combust coal before January 1, 2019, January 1, 2019; or

    • (b) in the case of a unit that ceases to combust coal on or after January 1, 2019, the day on which electricity generated from the boiler unit was first sold or distributed to the electric grid, in the calendar year in which the unit becomes subject to these Regulations.

  • Marginal note:Annual performance test

    (2) Performance tests are to be subsequently conducted annually to determine the CO2 emission intensity for the boiler unit in question, in accordance with subsection (3), for as long as the responsible person for that boiler unit does not have to meet the emission limit referred to in subsection 4(2).

  • Marginal note:Conditions — test

    (3) The initial and annual performance test must consist of a continuous test that lasts at least two hours and does not exceed 100% of the unit’s capacity.

  • Marginal note:Quantification

    (4) For the purposes of subsections (1) and (2),

    • (a) the quantity of energy produced by the unit must be determined in accordance with section 11; and

    • (b) the quantity of CO2 emitted by the unit must be determined in accordance with sections 12, 13 and 15 to 18, as applicable: however, all emissions must be quantified including those from the combustion of biomass.

  • Marginal note:Adaptation

    (5) For the performance test, the reference to “calendar year” in sections 11, 12, 15, 17 and 18 and in the Reference Method is replaced with a reference to “performance test period”.
