Air emissions - particulates (PM10)
AGL Loy Yang emissions increased 17% compared to FY21. Emissions are split roughly 50/50 between point source and fugitive sources. Point source emissions have increased over the past two years due to the ageing of the precipitator plant at AGL Loy Yang: by 67% from FY20 to FY21, and by 32% from FY21 to FY22.
Bayswater Power Station emissions increased 24% compared to FY21. Emissions are split roughly 25/75 between point source and fugitive sources. Point source emissions decreased 31%. Fugitive emissions, which include dust emissions and exhaust emissions from vehicles and equipment, increased 77%.
AGL Torrens emissions decreased 31% compared to FY21. The decrease aligns with a decrease in pipeline natural gas combustion at AGL Torrens (down 34%) and at Barker Inlet Power Station (down 33%).
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.
The National Assets were sold in FY19.
Emissions from Kwinana Swift 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.
