Carbon intensity of operated and controlled generation assets
The decrease in operated and controlled emissions intensity in FY23 was driven by the closure of Liddell Power Station, an extended outage at Loy Yang A Power Station Unit 2, the closure of Torrens Island A Power Station, and an increase in renewable generation. Market intensity decreased due to continued increase in renewable generation.
Notes
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.
Controlled intensity comprises total Scope 1 and 2 emissions divided by total sent out generation of electricity generation facilities which fit within AGL’s controlled boundary. AGL’s controlled boundary includes all electricity assets for which AGL has: operational control as defined by the National Greenhouse and Energy Reporting Act 2007; and/or contracted rights to control the dispatch of electricity of the asset.
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.
Average market 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).
FY23 data was updated in November 2023. At the time of the initial release of the FY23 ESG Data Centre on 10 August 2023, estimated FY23 data was provided based on measured emissions from material sources and measured electricity generation, with estimates for minor emissions sources. FY23 intensity figures have not changed upon revision.
