Major AGL offices comprise offices in Sydney (NSW), Brisbane (Qld), Bourke Street and Collins Street in Melbourne (Vic) and Eastwood (SA).

Where office buildings are occupied by multiple tenants, AGL's water consumption has been estimated based on property management data for the building, pro-rated to reflect the amount of building floor space occupied by AGL.

For the purposes of this data set, AGL Torrens comprises the Torrens Island Power Station and the Barker Inlet Power Station which commenced operation in December 2019.

Water consumption for AGL facilities located on customer sites is excluded as AGL does not typically hold a water contract at these sites.

Reporting for Kwinana Swift commenced in FY20 as AGL purchased the facility during FY20.

Aside from major offices, data for non-energy producing facilities is excluded where water consumption is not material.

A water meter was installed at the Wallumbilla site during FY20, which enabled water consumption to be accurately measured rather than estimated.

Data reported above excludes produced water from Camden Gas Project (refer to 'Produced water - volume').

Data reported above excludes water that is passed through AGL's hydro generation facilities (refer to 'Managed water').

Data reported above excludes water used for cooling at AGL Torrens (refer to 'Managed water').

During FY24, approximately 0.05% of AGL’s total water consumed was in regions of ‘High’ or ‘Extremely High’ baseline water stress, according to the World Resources Institute’s (WRI) Water Risk Atlas tool, Aqueduct.

Surface water consumption at AGL Macquarie is calculated based on pump flowmeter records for water extracted from the Hunter River, used to replenish water supplies in Lake Plashett and Lake Liddell, and not by how much water is consumed in operations.

For Kwinana Swift Power Station, FY22 water consumption data was used as a proxy for FY23. During FY24, WaterCorp provided actual data for FY23, which was revised to 46,200 kL.
