25  Calculating baseline emissions using methane sent to a combustion device or biogas upgrading system

       The baseline emissions for project treatment facility t for a reporting period are worked out using the following formula (equation 5):

       where:

       EB,t means the baseline emissions for project treatment facility t for the reporting period, in tonnes CO2-e.

       t is a project treatment facility.

         means the factor, set out in Part 5.3 of the NGER (Measurement) Determination, that converts cubic metres of methane to tonnes CO2-e at standard conditions.

            Note: In 2022, γ was 6.784 x 10-4 x 28.

       WEW,t means the proportion of methane generated at project treatment facility t  that is generated by eligible wastewater for the project during the reporting period, worked out in accordance with section 26.

       h means:
        (a) a combustion device used at project treatment facility t; or
        (b) a biogas upgrading system of a project biomethane facility.

       MSent t,h means the methane from project treatment facility t sent to combustion device or biogas upgrading system h during the reporting period, in cubic metres, worked out in accordance with section 30.

       WDAL means the proportion of methane that is generated in anaerobic digesters that would have been generated in deep open anaerobic lagoons that are part of project treatment facility t and were replaced as part of the project, which is:
          (a) if no anaerobic digesters installed at project treatment facility t as part of the project are engineered biodigesters—1; or
          (b) otherwise—0.75.
