Air emissions - particulates (PM10)
In FY19 emissions reported by AGL Torrens have increased slightly, mainly due to the increased combustion of fuel oil, whereas emissions increased at Somerton Power Station due to an increase in electricity generation. Emissions of PM10 have decreased at the Bayswater and Liddell power stations mainly due to variations in stack emission testing. Emissions decreased at AGL Loy Yang mainly due to increased unplanned outages whereas emissions decreased at Silver Springs Oil and Gas Project 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.
