23 Gross abatement amount for a project treatment facility
(1) The gross abatement amount for project treatment facility h for a reporting period, GAconversion, h (in tonnes CO2‑e), is worked out using the formula:
| | Equation 3 |
γ is the factor, used in Part 5.3 of the NGER (Measurement) Determination, that converts cubic metres of methane to tonnes CO2‑e at standard conditions.
MA (methane avoided) is the volume of methane avoided in the project treatment facility by diversion of material that includes volatile solids during the reporting period, calculated using equation 7 (section 25).
i is:
(a) a combustion device of project treatment facility h; or
(b) subject to subsection (2), a biogas upgrading system of a project biomethane facility.
MCh, i (methane combusted) is the volume of methane from project treatment facility h destroyed by combustion device i, or taken to have been destroyed by biogas upgrading system i, during the reporting period, calculated using equation 4 or equation 5 (section 24).
(2) For subsection (1), if the project works out its net conversion abatement for a reporting period under section 21 using Method 2, i is a combustion device of the project treatment facility h.
Note: This prevents biogas sent from project treatment facilities to biogas upgrading systems from being included when working out gross abatement under equation 3. This, in turn, prevents double-counting of conversion abatement from biomethane, which under Method 2 is already accounted for in equation 1B.
