Air emissions - particulates (PM2.5)
AGL Loy Yang emissions decreased 13%.
Bayswater Power Station emissions increased 62%. The observed increase in emissions directly align with the increase in PM10 measured via stack tests. PM2.5 emissions are calculated based on gas flow and PM10 stack tests, which also increased by 63% due to the increased measurements of PM10 at Units 3 and Unit 4.
AGL Torrens emissions increased 39%. 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 was updated in November 2025. A subset of data (comprising emissions associated with the combustion of black coal at Bayswater Power Station, 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 FY25 Data Centre on August 13. |
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. |
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. |
