Air emissions - carbon monoxide (CO)
Emissions for Bayswater and Liddell have increased in line with increased fuel combustion and electricity generation. Emissions from AGL Torrens have increased due to increased fuel oil combustion in FY19. Emissions at Camden have increased as a result of variations in stack emission testing. The emissions increase at Newcastle Gas Storage Facility was due to increased flaring activity in the reporting period. The decrease in emissions from AGL Loy Yang was due to a decrease in electricity generation resulting from unplanned outages. The emissions decrease at Silver Springs Oil and Gas Project is due to a decrease in fuel combustion. 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.
Air emission data is measured in CO(kg) and is rounded to nearest kilogram.
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.
FY15 data for Bayswater and Liddell power stations represents emissions from the facility for the full financial year, although AGL only commenced operating these facilities from 2 September 2014.
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.
