Air emissions - particulates (PM2.5)
In FY19 emissions at AGL Torrens have increased mainly as a result of the increased combustion of fuel oil for power generation whilst increased emissions at Somerton Power Station is due to increased electricity generation. Emissions at Bayswater and Liddell have decreased as a result of variations in stack emission testing. A decrease in emissions at AGL Loy Yang is mainly due to unplanned turbine outage whereas a decrease at Silver Springs Oil and Gas Project is due to a decrease in fuel combustion. Emissions decreased at Newcastle Gas Storage Facility mainly due to reduced operating hours of site boilers. Emissions for the National Assets were not reported in FY19 due to the portfolio of facilities being sold during FY19. The variation in emissions for other sites was generally consistent with the previous year.
FY19 data was updated in December 2019. 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) was reported with the initial release of the FY19 Annual Report on 08 August 2019.
All figures have been restated to the nearest kilogram.
Air emissions data for AGL sites is publicly reported NPI data. See www.npi.gov.au
Hydrocarbon Extractions ceased production in October 2014.
The National Assets were sold in FY19.
Wallumbilla LPG Plant became operational in 2016 hence NPI reporting commenced in FY17.
The emission factors used in AGL's NPI reports are sourced from relevant industry emission estimation technique manuals available on the NPI website.
