Water consumption by facility
In FY23, overall water consumption decreased, with a 7% decrease at AGL Loy Yang, 12% decrease at Bayswater Power Station and Liddell Power Station, 29% decrease at AGL Torrens, and 20% decrease at Silver Springs Gas Project.
The noticeable exception was Wallumbilla, which had a 337% increase in water consumption. This increase is attributable to a large amount of construction, including hydro excavation, which has increased water consumption. A leak in the underground water main was also ongoing for several months before it was repaired.
Camden Gas Project had a 70% increase in water consumption, due to the higher volume of water used for gas well decommissioning, as part of the closure of the Camden Gas Project.
Notes
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').
Data reported above excludes water used for cooling at Liddell Power Station (refer to 'Managed water').
During FY23, approximately 0.38% 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 (FY22: 0.38%).
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.
