Carbon intensity of operated and controlled generation assets

The greenhouse gas intensity of AGL's operated and controlled generation portfolios decreased in FY20 due to an increase in renewable energy generation and a decrease in brown coal generation. Market intensity decreased due to an increase in renewable generation.

Notes

  • FY20 controlled generation intensity was updated in December 2020. At the time of the initial release of the 2020 ESG Data Centre on 13 August 2020, estimated FY20 data was provided based on measured emissions from material sources and measured electricity generation, with estimates for minor emissions sources. After finalisation of AGL's emissions reporting in October 2020, the estimated intensity was updated from 0.93 to 0.94 tCO2e/MWh.

  • 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 Energy has: ownership; and/or 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).
