Air emissions - lead (Pb)
Bayswater Power Station emissions of lead decreased 21%. Point source lead emissions are calculated using stack test data and total gas flow allocated to each unit. The decrease in lead emissions was mostly driven by the lower measurements of lead for Unit 2, as measurements of lead for the other units were higher in FY23.
Liddell Power Station emissions of lead decreased 47%. Point source lead emissions are calculated using stack test data and total gas flow allocated to each unit. The decrease in lead emissions was mostly driven by the lower measurements of lead for Unit 4, and the decrease in operating hours.
AGL Torrens emissions of lead decreased 39%. 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 lead emissions at AGL Torrens.
Loy Yang emissions of lead increased by 14%. This is due to the 29% increase in fugitive lead emissions associated with mine operations.
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.
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.
