Air emissions - volatile organic compounds (VOC)

Bayswater Power Station total VOC emissions increased 125%. The increase in emissions was mostly driven by higher measurements of VOCs from stack tests, with noticeable increases in toluene (up 37%) and acetone (previously below the detection limit). This, combined with the 8% increase in operating hours, resulted in a significant increase in point source VOC emissions.

AGL Loy Yang total VOC emissions increased 9%. The increase in emissions is aligned with the increase in coal combustion (up 12%).

AGL Torrens total VOC emissions decreased 11%. The decrease in emissions aligns with the overall decrease in natural gas combustion at Torrens Island Power Station and Barker Inlet Power Station (down 12%).

Notes

FY24 data was updated on November 2024. 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 FY24 Data Centre on August 14.

For the purposes of this data set, AGL Torrens comprises the Torrens Island Power Station and the Barker Inlet Power Station.

All figures have been rounded to the nearest kilogram.

Emissions from Kwinana Swift Power Station have been 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.
