Alcoa has secured a gas offtake agreement with Woodside Energy for its Western Australian alumina refineries.
The agreement will provide a total of 31.1 petajoules of gas from 2027 to 2030.
Nick Eaton, Alcoa Energy Director for Australia, said the agreement provided important near-term energy supply for the company’s Western Australian (WA) operations and continued its longstanding relationship with Woodside.
He said: “This agreement with Woodside helps maintain reliable energy supply to our refineries, supporting thousands of regional jobs and Western Australian businesses associated with our operations.
“We continue to progress our broader energy strategy that includes planning for gas supply beyond 2030 and the integration of renewable energy sources into our portfolio.”
Alcoa directly employs about 4000 people in WA, with around 60% living in the Peel and South West regions.
In 2025, the company invested $2 billion with WA suppliers and provided $6.7 million in support to local community organisations.
With natural gas underpinning the energy requirements of Alcoa’s WA alumina refineries, they are among the lowest carbon emitting refineries in the global alumina industry (based on Alcoa and CRU (2025) industry analysis).
The alumina produced at the refineries is used to manufacture aluminium.
