24 Methane destroyed by combustion devices or taken to have been destroyed by biogas upgrading systems

(1) 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 a reporting period, MCh, i (in cubic metres), is calculated:

(a) for a combustion device that is an internal combustion engine used to generate electricity—using either Method A (set out in subsection (2)) or Method B (set out in subsections (3) and (4)); and

(b) otherwise—using Method A (set out in subsection (2)).

Method A—direct volume calculation

(2) To calculate MCh, i (the volume of methane from project treatment facility h, in cubic metres, destroyed by combustion device i, or taken to have been destroyed by biogas upgrading system i) by Method A, use the following formula:

| | Equation 4 |

Qbiogas h, i is the total volume of biogas from project treatment facility h sent to combustion device or biogas upgrading system i during the reporting period, in cubic metres, determined in accordance with the Supplement.

WBG, CH4 is the proportion of Qbiogas h, i that is methane, expressed as a fraction, determined in accordance with the Supplement.

PLi is the biomethane production loss factor for biogas sent to combustion device or biogas upgrading system i, expressed as a fraction, worked out in accordance with section 24B.

Note: PLi accounts for methane lost during biogas upgrading. It does not affect methane that is sent to combustion devices.

TLi is the transport loss factor for biogas sent to combustion device or biogas upgrading system i, expressed as a fraction, which is:

(a) if i is a combustion device—zero; or

(b) if i is a biogas upgrading system that sends biogas to a biogas upgrading system at a project biomethane facility and all biomethane produced by the biogas upgrading system during the reporting period is consumed at a project treatment facility or a project biomethane facility—zero; or

(c) otherwise—0.02.

Note: TLi accounts for methane that is not combusted due to gas lost in transport. It is only relevant when a project undertakes biomethane production and sends the gas off-site for use and combustion.

DEi is the methane destruction efficiency for combustion device or biogas upgrading system i, expressed as a fraction, determined in accordance with the Supplement.

Method B—calculation from power output

(3) To calculate MCh, i (the volume of methane from project treatment facility h, in cubic metres, destroyed by combustion device i) by Method B, use the following formula:
