AGL is the largest electricity generator in Australia, many of our generation plants involve the combustion of fuels resulting in emissions to air. We also operate gas production and storage assets which also produce air emissions.
Emissions to air from our operations can potentially contribute to regional airshed environmental issues, so it is important that our operations run efficiently and within the parameters set by regulatory licences. Undertaking regular maintenance helps keep equipment running efficiently and we monitor emissions to verify compliance with regulatory requirements.
Air emissions are reported to the Federal Government’s National Pollutant Inventory (NPI) each year. The NPI is a publicly available database of emissions from Australian industrial facilities.
FY16 saw some increases in NPI emissions data at AGL Macquarie, which were the direct result of improved emissions reporting since we acquired Bayswater and Liddell power stations. Since FY16, we have identified and implemented operating and maintenance efficiencies that have resulted in a reduction in emissions, as demonstrated in the data centre, which will be reflected in our FY17 NPI reports.
Emissions are also reported to state government regulators as required. As part of the Environment Protection Licences issued to Bayswater Power Station, Liddell Power Station, Rosalind Park Gas Plant (Camden Gas Project) and the Newcastle Gas Storage Facility by the New South Wales Environment Protection Authority (EPA), we are also required to publish air monitoring data on our website.
In the 2017 financial year we undertook to improve our air emissions management and monitoring. we did this by voluntarily implementing additional monitoring across AGL Macquarie and upgrading our controls at AGL Loy Yang.
