AGL Macquarie produces approximately 12% of the electricity needed by consumers in eastern Australia.

AGL Macquarie’s assets include the 2,640 MW Bayswater power station, the 2,000 MW Liddell power station and the 50 MW Hunter Valley gas turbines. AGL Macquarie is the former NSW Government power producer, Macquarie Generation, which AGL acquired in September 2014.

Over recent years Bayswater power station has produced approximately 15,000 GWh of electricity a year, enough power for two million average Australian homes and families. Liddell power station produces around 8,000 GWh of electricity or enough power for approximately one million average Australian family homes. 

Production from AGL Macquarie is equivalent to 30% of the electricity needs of New South Wales.

AGL Macquarie is the largest domestic buyer of NSW coal and employs approximately 650 people, most of who live in the Upper Hunter.

Pathway for the gradual decarbonisation of our generation portfolio

In April 2015, AGL revised its Greenhouse Gas Policy which presented a pathway for the gradual decarbonisation of our generation portfolio by 2050 along with a commitment not to extend the operating lives of our existing power stations. This means that the Liddell power station is the first scheduled power station to close in 2022, with Bayswater and Loy Yang to cease operation in the 2030s and 2040s.

Development and Maintenance

Bayswater power station was commissioned in 1985, and its design reflects the progress and improvements in power generation technology to maximise efficiency and minimise environmental impacts. The most distinctive feature of Bayswater power station is the four evaporative cooling towers.

With a commitment to the improvement of operation and technology upgrades, Bayswater will continue to be a centre piece of the NSW electricity system.

Liddell power station was commissioned in 1971, and for many years was the backbone of the NSW electricity system. Liddell was the first major power station to be located inland away from abundant salt water supplies traditionally used for cooling purposes. As a result Lake Liddell was constructed for cooling and water storage. 

Over recent years Liddell power station has benefited from technology upgrades, with significant environmental and operational gains.


Covering a total area of 10,000 hectares, Liddell and Bayswater power stations (and associated lands) are located between Singleton and Muswellbrook in the Upper Hunter Valley of NSW.
