Water consumption by facility
Water consumption at the Loy Yang A Power Station decreased by 15% compared to FY19, mainly due to a reduction in surface water consumption at the facility. There was a significant increase in surface water consumption at AGL Macquarie, due to increased water extraction from the Hunter River to replenish water supplies in Lake Liddell and Lake Plashett. Consumption of water at AGL Torrens (which includes the Barker Inlet Power Station) has remained relatively consistent with FY19 results.
Somerton Power Station water consumption has increased 28% compared to FY19. This total includes the newly reported waste water consumption from the demineralisation plant, as reported to Yarra Valley Water. AGL Hydro water consumption decreased by 47% compared to FY19, mainly due to the reduced figure reported for Eildon Power Station.
Camden water consumption has increased by 68% compared to FY19 figures. Silver Springs water consumption has remained relatively consistent with FY19 figures (increase of 7%). NGSF consumption decreased 29% compared to FY19 figures.
AGL Offices water consumption has declined by 35% compared to FY19, mainly due to a significant reduction in water consumption reported for the 699 Bourke Street Office. Electroserv water consumption has remained relatively consistent with FY19 figures.
Major AGL offices comprise offices in Sydney (NSW), Brisbane (Qld), Bourke Street and Collins Street in Melbourne (Vic) and Eastwood (SA). AGL relocated its Sydney and Brisbane offices in FY17.
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 FY20, approximately 0.4% 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.
