Overview

• Rio Tinto notified the market operator that Gladstone Power Station may retire in March 2029, six years earlier than the previously planned 2035 date.
• The company said no final decision has been made and the plant’s life could be extended if market conditions allow.
• Current power supply contracts, including for the Boyne aluminium smelter, remain in place until their March 2029 expiry with no planned reduction in output before then.
• Joint-venture participants will consult stakeholders on market conditions and future uses of the site to shape the retirement timeline and strategy.
• Reports say Rio has explored selling its 42% stake after securing renewable deals that cover most smelter demand but only part of firming needs, as the state extends Callide B to 2031 and environmental advocates welcome an orderly transition.
