Emissions intensity of generation
AGL's operated generation intensity increased in FY25, primarily due to reduced renewable generation following contract changes with Tilt Renewables for Broken Hill and Nyngan solar plants and Silverton and Coopers Gap wind farms at the end of FY24.
AGL’s operated and contracted greenhouse gas intensity (which includes contracted generation from the four Tilt Renewables assets) decreased in FY25, driven by the introduction of the Rye Park wind farm PPA commencing in April 2025, as well as higher gas-fired generation in South Australia, primarily driven by AEMO directed running of Torrens Island Power Station and higher generation during periods of volatility, alongside higher generation from wind and hydroelectric power stations in the second half of the year.
Additionally, a reduction in generation from Loy Yang A Power Station due to the planned Unit 4 major outage and unplanned outages at Bayswater Power Station in the second half of the year contributed to the decrease in the operated and contracted generation intensity, the fossil fuel generation intensity and the emissions intensity of electricity supplied, while helping to offset some of the increase in the operated intensity.
The emissions intensity of electricity supplied decreased in FY25, driven by decreased generation from Loy Yang A and Bayswater power stations, decreasing grid intensity, and decreased electricity sales in higher grid intensity states.
Operated generation 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 for electricity generation facilities which fit within AGL’s operated and contracted boundary. AGL’s operated and contracted boundary includes any grid-connected electricity assets (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. |
Fossil fuel capacity comprises coal-fired generation and gas-fired generation assets. |
Greenhouse gas emissions have been calculated in accordance with the National Greenhouse and Energy Reporting Scheme. |
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 emissions intensity based on data from the Carbon Dioxide Equivalent Intensity Index of the National Electricity Market, as published by AEMO. |
Greenhouse gas emissions include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride (as applicable). |
FY25 data was updated in November 2025. |
