Alcoa secures new gas supply for alumina refineries in Western Australia

Alcoa of Australia Limited (Alcoa) has secured three new gas supply agreements which combined will supply approximately 25 per cent of the Company's gas requirement in Western Australia (WA) from 2020.

The agreements with BHP, Woodside and Chevron coupled with other gas supply contracts, including with Quadrant Energy and Santos, announced in 2015, complete

Alcoa's gas portfolio to fuel its Kwinana, Pinjarra and Wagerup alumina refineries for the mid-term.

"In securing these new gas contracts we are demonstrating to our employees, suppliers, customers and the communities where we operate our commitment to the state," President, Alcoa Alumina, and Managing Director, Alcoa of Australia, Michael Parker said.

"Alcoa's three WA refineries are the largest integrated source of alumina globally and an important source of economic activity. They provide jobs for more than 3,000 Western Australians, primarily in the state's south west, and generate some $1.4 billion in expenditure with WA suppliers."

Alcoa is Western Australia's single largest user of natural gas, consuming approximately 40 per cent of the gas supplied to the south west of the state and about 25 per cent of the state's total domestic gas supply.
