Environmental Management

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:

  • meet or exceed statutory obligations
  • report environmental performance consistent with recognised standards
  • provide leadership and actively participate in the policy debate on energy and environmental matters
  • reduce risk and minimise environmental impact, and
  • consult with stakeholders on how best to achieve environmental objectives.

Environmental Monitoring

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.

Environmental Management Initiatives

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.

Solar Thermal Energy

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 has since been expanded with the assistance of the NSW Government Renewable Energy Development Fund, and in partnership with Novatec Solar.

Hydro Power

Advanced Emission Control Systems

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.
