Air emissions - sulphur dioxide (SO2)
AGL Torrens sulphur dioxide emissions decreased 93% compared to FY21. This is due to a reduction in the sulphur content factor in calculating sulphur dioxide emissions of the fuel oil used at Barker Inlet Power Station. Light fuel oil is the most significant source of sulphur dioxide emissions at AGL Torrens.
Liddell Power Station sulphur dioxide emissions increased 14%. The increase in emissions aligns with the increase in coal combustion (up 8%) and the corresponding increase in total electricity generated (up 11%).
Notes
FY22 data was updated in November 2022. A subset of the FY22 data (comprising emissions associated with the combustion of black coal and diesel at the Bayswater and Liddell power stations, black and brown coal as well as natural gas at AGL Loy Yang, and natural gas and fuel oil at AGL Torrens, and estimates of fugitive emissions at these sites) was reported with the initial release of the FY22 Annual Report and ESG Data Centre on 19 August 2022.
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.
The National Assets were sold in FY19.
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.
