Air emissions - sulphur dioxide (SO2)
AGL Torrens sulphur dioxide emissions decreased 32%. This is due to the 50% decrease in light fuel oil combustion at Barker Inlet Power Station from 9,159 tonnes in FY22 to 4,575 tonnes in FY23. Light fuel oil is the most significant source of sulphur dioxide emissions at AGL Torrens.
Liddell Power Station sulphur dioxide emissions decreased 32% in FY23. The decrease in emissions correlates to the decrease in sub-bituminous coal combustion (down 31%), and the decrease in total electricity generated (down 32%).
AGL Loy Yang sulphur dioxide emissions decreased 18% in FY23. The decrease in emissions is due to the decrease in electricity generation and fuel usage.
Notes
FY23 data was updated in November 2023. A subset of data (comprising emissions associated with the combustion of black coal at Bayswater and Liddell power stations, black and brown coal as well as natural gas at AGL Loy Yang Power Station, and gas and fuel oil at AGL Torrens Power Station) was reported with the initial release of the FY23 Data Centre on 10 August 2023.
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.
