Air emissions - volatile organic compounds (VOC)
Liddell Power Station emissions increased 64%. Measurements of individual VOCs were higher in FY22 compared to FY21, with noticeable increases for toluene (up 27%), benzene (up 8%), and acetone (previously below the detection limit). This, combined with the increase in operating hours, resulted in a significant increase in point source VOC emissions. Fugitive emissions also saw an increase in FY22 due to the increase in diesel storage and combustion.
AGL Torrens emissions decreased 36%. Emissions are calculated from the combustion of pipeline natural gas, light fuel oil, and diesel at AGL Torrens and Barker Inlet Power Station. The decrease in emissions aligns with the 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.
All figures have been rounded to the nearest kilogram.
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.
