Operational greenhouse gas footprint and net energy production
Decreased brown coal consumption at Loy Yang A Power Station due to outages largely drove the decrease in scope 1 emissions in FY22, with mothballing of the A3 and B1 units at Torrens Island Power Station and retirement of Unit 3 at Liddell Power station also contributing. The recovery from outages at Bayswater and Liddell power stations in FY21 largely drove the increase in scope 2 emissions in FY22. The increase in net energy production was driven by an increase in brown coal sales along with gas products, partly offset by reduced sent out generation from AGL's operated generation portfolio.
Notes
Includes scope 1 and 2 greenhouse gas emissions and net energy production for assets over which AGL had operational control during the period. This does not include assets where AGL controls or has rights to the electricity output only.
Greenhouse gas emissions and net energy production have generally been calculated in accordance with the National Greenhouse and Energy Reporting Act methodologies.
Net energy production incudes the sent-out generation from AGL's operated power stations, cogeneration steam production and gas sales from operated assets, coal sales from the AGL Loy Yang Mine and the production of LPG, condensate and gas at the Wallumbilla LPG plant. This does not include any energy production for use within AGL-operated facilities.
Greenhouse gas emissions are rounded to the nearest ktCO2e. Energy production is rounded to the nearest 10 TJ.
FY22 data was updated in November 2022. Data was not available at the time of the initial release of the FY22 ESG Data Centre on 19 August 2022.
