Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations

Version of section 24 from 2015-07-01 to 2018-11-29:


Marginal note:Quantification based on HHV

  •  (1) For an eligible fuel referred to in subsection (2), the quantity of CO2 emissions attributable to the combustion of the fuel in a unit during a calendar year, expressed in tonnes, may be determined in accordance with subsection (4) based on the following higher heating value of the fuel:

    • (a) the higher heating value of the fuel that is measured in accordance with subsection (6) as provided by the supplier of the fuel to the responsible person but, if not so provided, as so measured by the responsible person; and

    • (b) in the absence of a measured higher heating value of the fuel referred to in paragraph (a), the default higher heating value, set out in column 2 of Schedule 5, for the fuel’s type, as set out in column 1 but, in the absence of that default higher heating value, a default higher heating value for that fuel type established by a body that is internationally recognized as being competent to establish default higher heating values for fuels.

  • Marginal note:Eligible fuels

    (2) Eligible fuels are

    • (a) a fuel combusted in a unit in respect of which an exemption from the application of subsection 3(1) has been granted under subsection 7(4);

    • (b) a fuel referred to in section 23 that is combusted during the calendar year at less than any of the average daily rates referred to in subsection (3);

    • (c) a fuel listed in Part 4 of Schedule 5; and

    • (d) a fuel combusted in a standby unit.

  • Marginal note:Average daily rates

    (3) The average daily rates are

    • (a) for a solid fuel, 3 t/day;

    • (b) for a liquid fuel, 1900 L/day; and

    • (c) for a gaseous fuel, 500 standard m3/day.

  • Marginal note:Quantity of emissions

    (4) The quantity of emissions is to be determined in accordance with the following formula:

    Q × HHV × EF × 0.001

    where

    Q
    is the quantity of the fuel combusted in the unit during the calendar year determined
    • (a) for a solid fuel, in the same manner as the one used in the determination of Mf in the formula set out in paragraph 23(1)(a) and expressed in tonnes,

    • (b) for a liquid fuel, in the same manner as the one used in the determination of Vf in the formula set out in paragraph 23(1)(b) and expressed in kL, and

    • (c) for a gaseous fuel, in the same manner as the one used in the determination of Vf in the formula set out in paragraph 23(1)(c) and expressed in standard m3;

    HHV
    — expressed in GJ/tonne, for a solid fuel, in GJ/kL, for a liquid fuel, and in GJ/standard m3, for a gaseous fuel — is
    • (a) if paragraph (1)(a) applies, the weighted average higher heating value of the fuel, determined in accordance with subsection (5), based on fuel samples collected in accordance with section 27, and

    • (b) if paragraph (1)(b) applies, the default higher heating value, set out in column 2 of Schedule 5, for the fuel’s type, as set out in column 1 and, in the absence of that default higher heating value, a default higher heating value for that fuel type established by a body that is internationally recognized as being competent to establish default higher heating values for fuels; and

    EF
    is the default CO2 emission factor, set out in column 3 of Schedule 5, for that fuel listed in column 1 and, in the absence of that default CO2 emission factor, a default CO2 emission factor for that fuel established by a body that is internationally recognized as competent to establish default CO2 emission factors for fuels.
  • Marginal note:Weighted average

    (5) The weighted average higher heating value of the fuel is determined in accordance with the following formula:

    The formula for determining the weighted average higher heating value of a fuel is the quotient of the following two sums: the sum of the product resulting from the multiplication of HHVi and Qi for each sampling period “i” and the sum of Qi for each sampling period “i”.

    where

    HHVi
    is the higher heating value of, as the case may be, each composite sample, or sample, of the fuel for the ith sampling period measured in accordance with subsection (6), as provided by the supplier of the fuel to the responsible person but, if not so provided, as so measured by the responsible person;
    i
    is the ith sampling period referred to in section 27, with “i” going from the number 1 to n, where n is the number of those sampling periods; and
    Qi
    is the mass or volume, as the case may be, of the fuel combusted during the ith sampling period, expressed
    • (a) for a solid fuel, in the same manner as the one used in the determination of Mf in the formula set out in paragraph 23(1)(a) and expressed in tonnes,

    • (b) for a liquid fuel, in the same manner as the one used in the determination of Vf in the formula set out in paragraph 23(1)(b) and expressed in kL, and

    • (c) for a gaseous fuel, in the same manner as the one used in the determination of Vf in the formula set out in paragraph 23(1)(c) and expressed in standard m3.

  • Marginal note:Measurement of HHV

    (6) The higher heating value of a fuel is to be measured
