23  Ancillary emissions
 (1) The ancillary emissions associated with implementing an oil or gas fugitives (RTF) project in a reporting period, in tonnes CO2‑e, are worked out using the formula (equation 10):
where:
EAn means the ancillary emissions associated with implementing the project in the reporting period, in tonnes CO2‑e.
QElec means the quantity of electricity consumed from the operation of the project, in megawatt hours, worked out in accordance with the monitoring requirements.
EFElec means:
 (a) for electricity obtained from an electricity grid that is a grid in relation to which the NGA Factors document, in force on the declaration day, includes an emissions factor—that factor, in kilograms CO2‑e per kilowatt hour (or its equivalent of tonnes CO2‑e per megawatt hour); or
 (b) for electricity obtained otherwise (whether from a grid or not):
 (i) if the supplier of the electricity is able to provide an emissions factor that reflects the emissions intensity of the electricity (worked out in accordance with subsection (2)) and is applicable on the declaration day—that factor, in kilograms CO2‑e per kilowatt hour (or its equivalent of tonnes CO2‑e per megawatt hour); or
 (ii) otherwise—the emissions factor, in kilograms CO2‑e per kilowatt hour (or its equivalent of tonnes CO2‑e per megawatt hour), for off‑grid electricity included in the NGA Factors document in force on the declaration day.
QSE,j means the quantity of additional fuel type j combusted for stationary energy purposes from the operation of the project in the reporting period (if any), in units appropriate for the application of the energy content factor (ECj), worked out in accordance with the monitoring requirements.
ECj means the energy content factor of fuel type j combusted for stationary energy purposes in Part 1, 2 or 3 (as appropriate) of Schedule 1 to the NGER (Measurement) Determination, in gigajoules per kilolitre (or other appropriate units).
EFj,k means the emissions factor for each gas type k released due to the combustion of fuel type j for stationary energy purposes in Part 1, 2 or 3 (as appropriate) of Schedule 1 to the NGER (Measurement) Determination, in kilograms of CO2‑e per gigajoule of fuel type j.
Note: The emissions factor incorporates relevant oxidisation factors for the gas type.
 (2) For subparagraph (b)(i) of the definition of EFElec in subsection (1), the emissions factor must be worked out:
 (a) on a sent‑out basis; and
 (b) using a measurement or estimation approach that is consistent with the NGER (Measurement) Determination.
 (3) In working out the ancillary project emissions, the project proponent must include any emissions that are reasonably associated with any energy required for the collection, transport and combustion of a gas quantity combusted as part of the project.
 (4) This includes any
