Notification of potential retirement of Gladstone Power Station


01 October 2025
 

MELBOURNE, Australia-- The Gladstone Power Station (GPS) Joint Venture confirms that CS Energy has formally notified the Australian Energy Market Operator (AEMO) of the potential retirement of GPS in March 2029, aligning with the expiry of existing supply and operational arrangements.

The notification ensures compliance with the National Electricity Rules to provide notice of closure of electricity generators 3.5 years in advance. The notice period can be extended at any time.

No final decision has been made to retire GPS, which has operated since 1976, and there is potential to extend the life of the power station should market and other factors allow.

There is no immediate impact of this notification on GPS operations. Existing power supply contracts, including to Boyne Smelters Ltd, will remain in place until their scheduled expiry in March 2029.

The JV participants recognise the contribution of GPS to the Gladstone community and are committed to work with the operator NRG Gladstone Operating Services to ensure transparent and timely engagement with employees, contractors and suppliers throughout this process.

Between now and March 2029, the JV participants will engage with stakeholders on the energy market and on options for the future use of the site, which will inform the timeline and strategy for retirement of the facility.

GPS is an unincorporated joint venture of which Rio Tinto has a 42.125% stake. More information can be found here.

Notification was submitted to AEMO by CS Energy at the recommendation of the Joint Venture in CS Energy’s capacity as the nominated generator for GPS in the National Energy Market. CS Energy trades the output of GPS in excess of the Boyne Smelter requirements.
