44 Volume of methane sent to a combustion device
(1) The volume of methane sent to a combustion device during a reporting period, in cubic metres, is worked out using:
(a) for a combustion device that is not an internal combustion engine—sub‑method 1 in subsection (2); or
(b) for a combustion device that is an internal combustion engine—either:
(i) sub‑method 1 in subsection (2); or
(ii) sub‑method 2 in subsection (3).
Note: Sub‑method 1 uses the volume of biogas sent to a combustion device and sub‑method 2 uses the electricity produced by an internal combustion engine.
(2) The volume of methane sent to a combustion device during the reporting period, in cubic metres, is worked out using the formula (equation 18):

MSent,h means the volume of methane sent to combustion device h, in cubic metres.
QBG,h means the volume of biogas sent to combustion device h, in cubic metres, worked out in accordance with the monitoring requirements.
WBG,CH4 means the fraction of biogas that is methane, being:
(a) if this parameter is, or is required to be, monitored continuously—the fraction worked out in accordance with the monitoring requirements; or
(b) otherwise—the fraction mentioned in subsection 5.37(2) of the NGER (Measurement) Determination.
h means:
(a) a combustion device used during the reporting period; or
(b) if a single pipe is used to send methane to more than one combustion device during the reporting period and the combustion devices are of the same kind—all of those devices.
(3) The volume of methane sent to an internal combustion engine during the reporting period, in cubic metres, is worked out using the formula (equation 19):

MSent,h means the volume of methane sent to internal combustion engine h, in cubic metres.
QEG,h means the quantity of electricity generated by internal combustion engine h (whether supplied to the grid or used on‑site), in megawatt hours, worked out in accordance with the monitoring requirements.
FMWh→GJ means 3.6, being the factor to convert megawatt hours to gigajoules.
EEh means:
(a) the factor for the electrical efficiency of internal combustion engine h determined in accordance with:
