AGL Macquarie Power Stations

Learn about the past, present and future of one of Australia's largest power generation sites.

AGL Macquarie is one of Australia's major electricity generators. Around 620 people work at its 2,640 MW Bayswater power station and 2,000 MW (available 1,680 MW) Liddell power station. AGL Macquarie also operates the 50 MW Hunter Valley gas turbines.

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 meets approximately 35% of the electricity needs of New South Wales.

Location

Liddell and Bayswater power stations are located between Singleton and Muswellbrook in the Upper Hunter Valley of NSW.

Latest updates

AGL has previously indicated that Liddell would close in 2022, which after 50 years of operation will have reached the end of its technical life.

AGL in August 2019 informed AEMO that the first unit at Liddell will close in April 2022. However, following an independent engineering assessment, AGL has determined that the remaining three units will close in April 2023, supporting system reliability throughout the 2022-23 summer months.

AGL's rehabilitation and transition plans

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.

Acquisition conditions

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.
