EFElec is:
(a) for electricity obtained from an electricity grid that is a grid in relation to which the NGA Factors document, in force at the end of the reporting period, includes an emissions factor—that factor, in kilograms CO2‑e per kilowatt hour; or
(b) for electricity obtained from an electricity grid not covered by paragraph (a) or obtained from a source other than an electricity grid:
(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 (4)) and is applicable at the end of the reporting period—that factor, in kilograms CO2‑e per kilowatt hour (or its equivalent of tonnes CO2‑e per megawatt hours); or
(ii) otherwise—the emissions factor, in kilograms CO2‑e per kilowatt hour (or its equivalent of tonnes CO2‑e per megawatt hours), for off‑grid electricity included in the NGA Factors document in force at the end of the reporting period.
(4) For subparagraph (b)(i) of the definition of EFElec in subsection (3), 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.
