Air emissions - lead (Pb)

Bayswater Power Station emissions of lead increased 178%.

Liddell Power Station emissions of lead increased 104%.

Torrens Island Power Station emissions of lead increased 15%. This is due to the increase in light fuel oil combustion at Barker Inlet Power Station from 1,074 tonnes in FY21 to 9,159 tonnes in FY22. Light fuel oil is the most significant source of lead emissions at AGL Torrens.

AGL Loy Yang emissions of lead decreased 7%. The decrease in point source emissions is aligned with the decrease in coal combustion (down 8%) and corresponding total electricity generation (down 8%) in the reporting period.

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.
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.
