Carbon intensity of generation
AGL's operated generation intensity increased in FY25, primarily due to reduced renewable generation following contract changes with Tilt Renewables at the Broken Hill and Nyngan solar plants, as well as the Silverton and Coopers Gap wind farms at the end of FY24.
AGL’s operated and contracted generation intensity decreased in FY25, driven in part to the retention of power purchase agreements (PPAs) across the four Tilt Renewables assets and the introduction of the Rye Park wind farm PPA commencing in April 2025. There was higher gas generation in South Australia primarily driven by AEMO directed running of Torrens Island Power Station as well as higher generation during periods of volatility. There was also higher generation from wind and hydroelectric power stations in the second half of the year.
Additionally, a reduction in generation at AGL Loy Yang due to the planned Unit 4 major outage and unplanned minor outages at Bayswater Power Station in the second half of the year contributed to the decrease in the operated and contracted intensity and the fossil fuel intensity, while helping to offset some of the increases in the operated generation intensity.
Operated intensity comprises total Scope 1 and 2 emissions divided by total sent out generation of electricity generation facilities which fit within AGL’s operated boundary. Operational control is as defined by the National Greenhouse and Energy Reporting Act 2007. |
Operated and contracted intensity comprises total Scope 1 and 2 emissions divided by total sent out generation of electricity generation facilities which fit within AGL’s operated and contracted boundary. AGL’s operated and contracted boundary includes any grid connected electricity asset (generation or storage asset excluding behind the meter assets): a) which AGL has operational or financial control of, as defined by the National Greenhouse and Energy Reporting Act 2007; or b) in respect of which AGL has virtual or physical offtake or nomination rights, in proportion to AGL's share of such rights. |
Greenhouse gas emissions have generally been calculated in accordance with methodologies under the National Greenhouse and Energy Reporting Act 2007. |
Electricity generation is measured on a 'sent-out' basis at the power station gate. |
Emissions intensity of electricity supplied is measured as the emissions associated with the maximum of either AGL's electricity supply to the wholesale of retail market by state, as a proportion of that same volume. |
National Electricity Market average intensity is the weighted average Carbon Dioxide Equivalent Intensity Index of the National Electricity Market, as determined from data published by AEMO. |
Greenhouse gas emissions include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride (as applicable). |
FY25 emissions data is estimated based on material fuels and will be finalised in November 2025. |
