Liddell Power Station

Liddell Power Station

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. The Lake now also serves as a water recreation source and unique habitat for a variety of wildlife.

Each year Liddell Power Station produces around 10,000 GWhs of electricity, or enough power for approximately 1.25 million average Australian family homes.

Over recent years Liddell Power Station has benefited from substantial technology upgrades, with significant environmental and operational gains. This process continues and will ensure operation well into the future.
