Quantity of energy 11 (1) The quantity of energy produced by a given unit is determined by the formula G + (0.75 × H pnet ) where G is (a) the gross quantity of electricity generated by the unit in the calendar year expressed in GWh, as measured at the electrical terminals of the generators of the unit using meters that comply with the requirements of the Electricity and Gas Inspection Act and the Electricity and Gas Inspection Regulations , or (b) in the case of a hybrid configuration – when the unit is either a combustion engine unit that shares a steam turbine with a boiler unit or a boiler unit that shares a steam turbine with a combustion engine unit – the quantity of electricity generated by the given unit in the calendar year expressed in GWh, determined by the formula in subsection (2); and H pnet is the net quantity of useful thermal energy produced by the unit in a calendar year, expressed in GWh, determined by the formula in subsection (3). Quantity of electricity — hybrid configuration (2) The quantity of 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 GWh, as measured at the electrical terminals of the generators of the combustion engines using meters that comply with the requirements of the Electricity and Gas Inspection Act and the Electricity and Gas Inspection 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 GWh, as measured at the electrical terminals of the generators of the shared steam turbine using meters that comply with the requirements of the Electricity and Gas Inspection Act and the Electricity and Gas Inspection 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 GWh 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 GWh, as measured at the electrical terminals of the generators of the shared steam turbine using meters that comply with the requirements of the Electricity and Gas Inspection Act and the Electricity and Gas Inspection 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 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, M ext_j is the mass flow of the j th external
