Rio Tinto Bell Bay Aluminium Power Agreement Extends Smelter Life to 2031

Rio Tinto Limited (ASX: RIO) has secured a power arrangement that keeps Bell Bay Aluminium running until 31 Dec 2031. Hydro Tasmania will keep supplying electricity until that date. The Australian and Tasmanian Governments will provide extra support.

The Bell Bay aluminium power agreement replaces a supply contract that ends on 31 Dec 2026. For the Company, it delivers Rio Tinto energy supply stability at a smelter that faced real doubt this year. Rio Tinto warned in April that continued operation was uncertain.

Governments Step In Where Commercial Terms Fell Short

Hydro Tasmania said it negotiates on commercial terms. According to Chief Executive Rachel Watson, any gap is addressed through government support. Media reports put the package at A$200 million from the federal and Tasmanian governments. The Company’s release does not state a dollar value.

Rio Tinto Aluminium & Lithium Chief Executive Jérôme Pécresse said the agreements bring “increased certainty for our people, suppliers and the northern Tasmanian community.” He thanked both governments, Hydro Tasmania and the workforce.

Bell Bay Smelter by the Numbers

Rio Tinto Bell Bay Aluminium began operating in 1955. According to Rio Tinto, it was the first aluminium smelter in the Southern Hemisphere. The Company owns 100% of the site.

Confirmed Terms Stay Narrow While Details Are Finalised

• Hydro Tasmania describes the deal as agreed in principle.
• Final details are expected in the coming weeks.
• Rio Tinto says the support will maintain the smelter’s international competitiveness.
• The A$200 million figure comes from media reports, not the Rio Tinto release.
• Further terms of the support were not published on 1 Oct 2026.

Bell Bay Joins Tomago and Boyne on a Growing Support List

Reports put government support across Rio Tinto’s three Australian smelters near A$5 billion. Bell Bay is the smallest of them.

Political Reaction Splits Along Familiar Lines

Industry Minister Tim Ayres called the arrangement a sound deal for taxpayers. Prime Minister Anthony Albanese, who visited the smelter, linked the support to sovereign capability and local manufacturing.

Opposition spokesman Andrew Hastie argued that Australians are paying for Labor’s energy and climate policies. He said bailouts have exceeded A$8 billion since 2022. The Communications Electrical and Plumbing Union said the deal protects jobs and industrial capability.

Nearly Six Years of Talks Set Up a Late Breakthrough

Rio Tinto spent almost six years negotiating a new power agreement with the Tasmanian Government, according to the AFR. Bell Bay was also reportedly ruled ineligible for the planned A$2 billion Green Aluminium Production Credit, according to news.com.au.

Local pressure added urgency. Susie Bower, Chief Executive of the Bell Bay Advanced Manufacturing Zone, said securing the smelter was critical after the Liberty Bell Bay closure. That manganese smelter sits about one kilometre away.

Industry Outlook

Aluminium smelters are Australia’s biggest electricity consumers, so power pricing shapes their survival. Aluminium prices rose 17% over the period covered by Rio Tinto’s latest full-year results, reported in Feb 2026. Governments are framing support as a matter of supply chain resilience and sovereign capability.

Final Contracts Will Set the Limits of Bell Bay’s Stability

• Impact on Bell Bay jobs: Operations are secured to 31 Dec 2031, covering about 550 full-time and 1200 indirect jobs.
• Impact on Tasmania’s energy system: The smelter uses more than 25% of the state’s electricity, so final supply terms matter to Hydro Tasmania.
• Impact on Rio Tinto’s Australian aluminium chain: Bell Bay’s outlook is secured to 2031, though the Company has not disclosed commercial terms. Rio Tinto says the chain directly employs over 5000 people.

Mining Herald will report the final terms when they are confirmed.
