27  Methane sent to combustion device or biogas upgrading system

        (1) Methane sent to a combustion device h or biogas upgrading system h during a particular period may be worked out using:
           (a) for a combustion device or biogas upgrading system—equation 10; or
           (b) for a combustion device—equation 11; or
           (c) for a combustion device that is an internal combustion engine—equation 12.

       Option 1—using landfill gas sent to combustion device or biogas upgrading system

        (2) Using the volume of the landfill gas sent to the combustion device or biogas upgrading system (QLFG,h), the methane sent to the combustion device or biogas upgrading system during the period is worked out using the formula (equation 10):

       where:

       MSent, h means the methane sent to the combustion device or biogas upgrading system h during the period, in cubic metres.

       QLFG, h means the landfill gas sent to the combustion device or biogas upgrading system h during the period, in cubic metres, worked out in accordance with the monitoring requirements.

       W LFG, CH4, h means the proportion of the landfill gas sent to combustion device or biogas upgrading system h that is methane, which is, subject to subsection (2A), at the election of the project proponent:
           (a) 0.42; or
           (b) worked out in accordance with the monitoring requirements; or
           (c) if the project is a landfill gas (electricity generation) project whose application under section 22 of the Act was made before 1 September 2020—set out in section 5.14C of the NGER (Measurement) Determination.

        (2A) If h is a biogas upgrading system, WLFG, CH4, h must be worked out in accordance with the monitoring requirements.

        (3) If, at any time during which this determination is, or the 2015 LFG determination was, the applicable methodology for the project, the monitoring requirements are or, as the case may be, were used to work out WLFG, CH4, h, then, the monitoring requirements must be used for that purpose for the remainder of the project.

        (4) Subsection (3) has effect subject to section 36.

       Option 2—using energy content of landfill gas sent to combustion device

        (5) Using the energy content of the landfill gas sent to the combustion device (QEn,h), the methane sent to the combustion device during the period is worked out using the formula (equation 11):

       where:

       MSent, h means the methane sent to the combustion device h during the period in cubic metres.

       QEn, h means the energy content of the landfill gas sent to the combustion device h during the period, in gigajoules, worked out in accordance with the monitoring requirements.

       ECLFG means the energy content factor for landfill gas that is collected for combustion (methane only), in gigajoules per cubic metre, set out in
