Air emissions - particulates (PM2.5)
AGL Loy Yang emissions decreased 21%. The decrease in emissions aligns with the decrease in coal combustion (down 9%) and total electricity generation (down 8%) in the reporting period.
Bayswater Power Station emissions increased 32%. Point source emissions are calculated using PM2.5 measured via stack tests and total gas flow allocated to each unit. The increase in emissions was primarily driven by higher measurements of PM2.5 at Unit 1 and Unit 2.
Liddell Power Station emissions decreased 62%. Point source emissions are calculated using PM2.5 measured via stack tests and total gas flow allocated to each unit. The decrease in emissions can be attributed to the decrease in operating hours.
AGL Torrens emissions decreased 25%. The decrease in emissions aligns with the overall decrease in pipeline natural gas combustion at Torrens Island and Barker Inlet power stations (down 23%).
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.
Emissions from Kwinana Swift Power Station have been included since 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.
