Air emissions - mercury (Hg)
AGL Loy Yang emissions of mercury decreased 32%. The decrease in point source emissions was resultant from a 25% decrease of mercury in stack tests, combined with lower operating hours across all 4 units including a 24% reduction in Unit 4.
Bayswater Power Station emissions of mercury increased 14%. Units 1 and 4 had higher measurements of mercury in their stack test results and increased operating hours compared to FY24.
AGL Torrens mercury emissions increased 37%. The increase in emissions aligns with the overall increase in pipeline natural gas combustion at Torrens Island Power Station and at Barker Inlet Power Station (up 40%).
FY25 data was updated in November 2025. A subset of data (comprising emissions associated with the combustion of black coal at Bayswater Power Station, black and brown coal as well as natural gas at AGL Loy Yang Power Station, and gas and fuel oil at AGL Torrens) was reported with the initial release of the FY25 Data Centre on August 13. |
For the purposes of this data set, AGL Torrens comprises the Torrens Island Power Station and the Barker Inlet Power Station. |
Air emissions data for AGL sites is publicly reported NPI data (see www.npi.gov.au). |
The emission factors used in AGL's NPI reports are sourced from relevant industry emission estimation technique manuals available on the NPI website. |
