Output-Based Pricing System Regulations — 2
2 If a combustion engine unit and a boiler unit share the same steam turbine, the quantity of gross electricity generated by a given unit is determined by the formula G ce + G s – G ext where G ce is the gross quantity of electricity that is generated by the generators of the combustion engines in a combustion engine unit that shares a steam turbine with a boiler unit, in the calendar year, expressed in Gigawatt hours, as measured at the electrical terminals of the generators of the combustion engines using meters that comply with the requirements set out in subsection 31(2) of these Regulations, if the given unit for which the electricity is being quantified is a combustion engine unit, or equal to zero, if the given unit for which the electricity is being quantified is a boiler unit; G s is the gross quantity of electricity that is generated by the generators of the shared steam turbine in the calendar year, expressed in Gigawatt hours, as measured at the electrical terminals of the generators of the shared steam turbine using meters that comply with the requirements set out in subsection 31(2) of these Regulations; and G ext is the quantity of electricity that is generated by the unit other than the given unit for which the electricity is being quantified, in the calendar year, expressed in Gigawatt hours and that is determined by the formula Gext is equal to Gs, multiplied by the summation for all time periods “t” of a quotient where the numerator is the summation of the products of hext,j and Mext,j for each heat stream “j”, and the denominator is the summation of the products of hext,j and Mext,j for each heat stream “j” plus the summation of the products of hint,k and Mint,k for each heat stream “k”. where G s is the gross quantity of electricity that is generated by the generators of the shared steam turbine in the calendar year, expressed in Gigawatt hours, as measured at the electrical terminals of the generators of the shared steam turbine using meters that comply with the requirements set out in subsection 31(2) of these Regulations, t is the t th hour, where “t” goes from the number 1 to x and where x is the total number of hours during which the generators of the shared steam turbine generated electricity in the calendar year, j is the j th external heat stream, originating from the other unit where “j” goes from the number 1 to m and where m is the total number of external heat streams that contributed to the electricity generated by the generators of the shared steam turbine of the unit, h ext,j is the average specific enthalpy of the j th external heat stream, originating from the other unit that contributed to the electricity generated by the generators of the shared steam turbine, expressed in gigajoules/tonne, during period “t” and must be based on the measurement of the temperature and pressure of that heat stream and determined using a continuous measuring device, M ext,j is the mass flow of the j th external heat stream originating from the other unit that contributed to the electricity generated by the generators of the shared steam turbine, expressed in tonnes, during period “t”, determined using a continuous measuring device, k is the k th internal heat stream originating from the given unit, where “k” goes from the number 1 to l and where l is the total number of heat streams that originated from the combustion of fuel in the unit and that contributed to the electricity generated by the generators of the shared steam turbine, h int,k is the average specific enthalpy of the k th internal heat stream originating from the given unit and having contributed to the electricity generated by the generators of the shared steam turbine, expressed in GJ/tonne, during period “t” and must be based on the measurement of the temperature and pressure of that heat stream and determined using a continuous measuring device, and M int,k is the mass flow of the k th internal heat stream originating from the given unit th
