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.
Liddell and Bayswater power stations are located between Singleton and Muswellbrook in the Upper Hunter Valley of NSW.
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.
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.
The PDF below provides an indication of AGL’s future compliance with the conditions:
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.

AGL Macquarie is actively involved in the Hunter Valley community, not only by contributing to the local economy but also as an active partner in community development.
Since the announcement of closure dates for Liddell and Bayswater, AGL has been working with local business, industry, government and educational institutions to identify new investment prospects, encourage economic diversification and create new employment opportunities in the Hunter.
Through our Community Sponsorship Program, AGL Macquarie proudly supports a variety of organisations that make valuable contributions to local Hunter communities. Our aim is to enhance quality of life for people in the Hunter region; and to encourage good citizenship amongst our employees.
If your local organisation seeks support for upcoming activities or events, AGL Macquarie encourages you to get in touch via our application form. Your application will go to an advisory committee, which meets regularly to assess applications and allocate support.
We are proud of our safety record at AGL Macquarie. To help us maintain our excellent standards, we ask that all visitors to Liddell and Bayswater power stations complete an online induction. This guides you through the rules you must follow while onsite.
The induction takes about 15 minutes and is then valid for one year. Once you have completed the induction, please print the certificate and bring it to your site visit.
Please remember that your contact at AGL Macquarie needs to advise our security staff of the dates and times you are visiting.

In April 2015, we committed to two key changes to our Greenhouse Gas Policy. The first is the gradual decarbonisation of our generation portfolio by 2050; the second is a decision not the extend the operating lives of our existing coal-fired power stations.
As a result of our Greenhouse Gas Policy:
- Liddell power station is scheduled to close in 2022
- Bayswater power station is scheduled to close in 2035
- AGL’s Greenhouse Gas Policy (2015)
- A Carbon Constrained Future (2016)
- AGL’s Rehabilitation Report (2017)
Liddell and Bayswater's operations are monitored by the NSW EPA, which receives round-the-clock data on environmental performance. AGL Macquarie also maintains five ambient air quality monitoring stations around the power stations.
As per the Protection of the Environment Legislation Amendment Act 2011, AGL must publish monthly monitoring data for each power station on our website. Find this data on our environmental monitoring page.
