Air emissions - sulphur dioxide (SO2)
AGL Loy Yang sulphur dioxide emissions decreased 9% in FY25. The decrease in emissions aligns with the decrease in coal combustion (down ~10%).
Bayswater Power Station sulphur dioxide emissions increased 5% in FY25. The observed increase in emissions occured despite the slight decrease in sub-bituminous coal combustion (down 3%). Sulphur dioxide emissions are influenced by the quantity of sulphur in the coal.
AGL Torrens sulphur dioxide emissions increased 33%. This was driven by the 40% increase in pipeline natural gas combustion at Torrens Island Power Station and Barker Inlet Power Station.
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. |
All figures have been rounded to the nearest kilogram. |
Continuous Emission Monitoring System (CEMS) was introduced to Units 2, 3 and 4 at Bayswater Power Station in November 2017. |
Emissions from Kwinana Swift Power Station have been 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. |
