AGL’s environmental management program is risk-based and driven by a desire to prevent harm to the environment in areas where AGL operates.
AGL is committed to achieving excellence in environmental management and performance.
AGL’s approach to environmental management is also guided by the AGL Environmental Principles. Key elements of the principles include commitments to:
Liddell and Bayswater's operations are monitored by the EPA which receives around the clock data on power station environmental performance. AGL Macquarie also maintains five ambient air quality monitoring stations around the power stations.
The Protection of the Environment Legislation Amendment Act 2011 requires that we publish on our website the monthly monitoring data for each power station. This data can be viewed on the Monitoring Data page.
AGL Macquarie has benefited from investment in a range of environmental management initiatives and renewable energy projects to complement the existing suite of power generation facilities.
Originally in partnership with Ausra Australia, the former Macquarie Generation built Australia's largest solar thermal energy project at Liddell power station. This was the first time anywhere in the world that solar thermal technology had been integrated with a coal-fired power station. The original pilot mirror array was then expanded to cover an area of 18,000 square metres or approximately three football fields, with over 500 mirror panels, each 12 metres by two metres. With support from the NSW Government Renewable Energy Development Fund, this project has been expanded in partnership with Novatec Solar. The project now has the capacity to produce renewable energy for over 1000 homes each year.
A 0.85 MW capacity hydroelectric generator is also in service. The turbine is driven by water fed to Liddell and Bayswater power stations via a canal from the Plashett Reservoir. The generator extracts energy from the movement of the water to the power stations.
Liddell and Bayswater have advanced emission control systems that trap ash created by burning coal. The ash is stored on site and used in valuable applications including cement making, road construction and land rehabilitation.
