Development and maintenance
Liddell power station was commissioned in 1971, and for many years was the backbone of the NSW electricity system. It was the first of its kind to be located inland – far from the abundant salt water supplies traditionally used for cooling purposes. As a result, Lake Liddell was constructed for cooling and water storage.
Bayswater power station was commissioned in 1985, and its design reflects the progress and improvements in power generation technology. Four evaporative cooling towers stand out as the site's most distinctive feature.
AGL acquired Liddell and Bayswater power stations – previously known collectively as Macquarie Generation – from the NSW Government in September 2014. Over recent years, technology upgrades and improved maintenance have delivered significant environmental and operational gains at both sites.
AGL is fully committed to complying with the conditions set out in the Australian Competition Tribunal’s authorisation of the acquisition of AGL Macquarie in 2014.
As part of these conditions, there is a requirement for AGL to have offered and/or to have entered into a minimum number of baseload swap contracts to licenced eligible NSW electricity retailers subject to the conditions outlined in the authorisation.
Compliance with these conditions is verified by independent quarterly audits, copies of which are provided to the Australian Competition and Consumer Commission.

It is important to note that compliance with the conditions does not of itself preclude AGL quoting outside its parameters, and AGL remains willing to consider all quote requests where possible.
