Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations — 21
Quantification 21 (1) If paragraph 20 (1)(a) applies, the quantity of CO 2 emissions referred to in subsection 20 (1) is to be determined in accordance with the following formula: E u – E bio + E non-ccs where E u is the quantity of CO 2 emissions, expressed in tonnes, from the unit, “u”, during the calendar year from the combustion of fuel, as measured by the CEMS in accordance with sections 7.1 to 7.7 of the Reference Method; E bio is the quantity of CO 2 emissions, expressed in tonnes, from the combustion of biomass in the unit during the calendar year, determined (a) by using a fuel-based method (i) in accordance with paragraph 24 (1)(a) or (b), if the unit combusts solid biomass at an average daily rate of less than 3t/day during the given calendar year, and (ii) in accordance with the applicable formula set out in one of paragraphs 23 (1)(a) to (c) for the type of biomass combusted, in any other case, or (b) by using the method, based on data from the CEMS, described in subsection (2); and E non-ccs is the quantity of CO 2 emissions, expressed in tonnes, from the combustion of fuel in the unit, including those emissions referred to in subsection 3 (4), during the calendar year — other than the quantity of those emissions as measured by the CEMS and set out in the description of E u — that is determined using a direct measure of the flow of, and the concentration of CO 2 in, the emissions from that combustion of fuel but that is not ultimately captured, transported and stored as described in subsection 3 (5). E bio based on CEMS data (2) For the purpose of determining the value of E bio , the method, based on data from the CEMS, consists of making the following sequence of determinations: (a) the volume of CO 2 emitted from combustion of fuel in the unit for each hour of production of electricity during the calendar year determined in accordance with the following formula: 0.01 × %CO 2w,h × Q w,h × t h where %CO 2w,h is the average concentration of CO 2 in relation to all gases in the stack emitted from the combustion of fuel in the unit during a given hour, “h”, during which the unit produced electricity in the calendar year — or, if applicable, a calculation made in accordance with section 7.4 of the Reference Method of that average concentration of CO 2 based on a measurement of the concentration of oxygen (O 2 ) in those gases in the stack — expressed as a percentage on a wet basis, Q w,h is the average volumetric flow during that hour, measured on a wet basis by the stack gas volumetric flow monitor, expressed in standard m 3 , and t h is the period during which the unit produced electricity, expressed in hours; (b) the volume of CO 2 emitted from combustion of fossil fuel in the unit during the calendar year, expressed in standard m 3 and referred to in this subsection as V ff , determined in accordance with the following formula: The formula for determining the volume of CO2 emissions emitted from the combustion of fossil fuel in the unit during the calendar year is the sum of the products resulting from the multiplication of Qi, Fc,i and HHVd,i for each fossil fuel type “i” combusted in the unit during the calendar year. where Q i is the quantity of fossil fuel type “i” 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 M f 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 V f 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 V f in the formula set out in paragraph 23 (1)(c) and expressed in standard m 3 , i is the i th fossil fuel type combusted in the unit during the calendar year, with “i” going from the number 1 to n, where n is the number of fossil fuels so combusted, F c,i is the fuel-specific carbon-based F-factor fo
