Air emissions - volatile organic compounds (VOC)
AGL Loy Yang total VOC emissions decreased 5%. Point source emissions are calculated using the quantity of fuel combusted and relevant industry emission factors. The decrease in emissions is aligned with the decrease in coal combustion (down 10%).
Bayswater Power Station total VOC emissions increased 33%. Point source emissions are calculated using the summed total of individual VOCs measured in stack tests. The increase in emissions was mostly driven by higher measurements of VOCs from stack tests, with noticeable increases for acetone (up >500%). Higher measurements of VOCs are generally indicative of diesel combustion at the time of testing. Compared to FY24, diesel combustion at the power station increased 47%.
AGL Torrens total VOC emissions increased 37%. The increase in emissions aligns with the overall increase in pipeline natural gas combustion at Torrens Island Power Station and Barker Inlet Power Station (up 40%).
FY25 data includes emissions associated with the combustion of black coal and diesel at the Bayswater Power Station, black and brown coal as well as natural gas at AGL Loy Yang, and natural gas and fuel oil at AGL Torrens. It also includes estimates of fugitive emissions at these sites. The remaining data will be made available in November 2025. |
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. |
