Air emissions - particulates (PM₁₀)

AGL Loy Yang emissions decreased 6%. Emissions are split roughly evenly between point source and fugitive sources. Point source emissions have decreased due to the decrease in coal combustion (down 9%) and total electricity generation (down 8%). Fugitive emissions include dust emissions and exhaust emissions from vehicles and equipment, and there was little change from FY22.

Bayswater Power Station emissions increased 6%. Emissions are split roughly 25/75 between point source and fugitive sources. Point source emissions, which are calculated using PM10 measured via stack tests and gas flow, increased 34%, while fugitive emissions decreased 4%.

Liddell Power Station emissions decreased 23%. Point source emissions are calculated using PM10 measured via stack tests and total gas flow allocated to each unit. The decrease in point source emissions can be attributed to lower measurements of PM10 in stack test results and decrease in operating hours. There was little change in fugitive emissions since FY22.

AGL Torrens emissions decreased 25%. The decrease in emissions aligns with the overall decrease in pipeline natural gas combustion at Torrens Island and Barker Inlet power stations (down 23%).
