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 includes emissions associated with the combustion of black coal and diesel at the Bayswater Power Station, black and brown coal as well as natural gas at AGL Loy Yang, and natural gas and fuel oil at AGL Torrens. It also includes estimates of fugitive emissions at these sites. The remaining data will be made available in November 2025. |
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. |
Emissions from Kwinana Power Station were included from FY20. |
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. |
