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%).
