Alcoa of Australia has announced a new gas offtake agreement with Woodside Energy Limited (Woodside) for its Western Australian alumina refineries. 

The agreement will provide a total of 31.1 petajoules of gas from 2027 to 2030.

Alcoa Energy Director Australia Nick Eaton said the agreement provided important near-term energy supply for the company’s Western Australian operations and continued its longstanding relationship with Woodside.

“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,” Mr. Eaton said.

Alcoa directly employs about 4000 people in WA, with around 60 per cent 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 in the global alumina industry.*

Alumina produced at the refineries is used to manufacture aluminium, one of the world’s most versatile metal  being light weight, high strength and corrosion resistant. Aluminium is key for energy infrastructure and decarbonisation technologies.

*Use of natural gas as an energy source means Alcoa’s WA refineries are among the lowest carbon emitting in the global alumina industry (based on Alcoa and CRU (2025) industry analysis). The WA refinery portfolio has an average emissions intensity that is no more than 0.6 metric tonnes of carbon dioxide equivalents per tonne of alumina produced, including both direct and indirect (Scope 1 and Scope 2) emissions from bauxite mining and alumina refining. Amended from the 2025 Sustainability Report.
