Australian LNG player Woodside Energy signed a long-term gas sale and purchase agreement (GSPA) with Alcoa of Australia for the supply of up to 36.4 PJ of pipeline gas.

Supply will commence in 2020 from Woodside’s portfolio of domestic gas facilities, including the North West Shelf, Pluto and Wheatstone, the company said in a statement.

Woodside CEO Peter Coleman said, “In addition to our foundation domestic gas business which supplies from the North West Shelf, Woodside will be able in coming months to deliver domestic gas from our Pluto facility and from Wheatstone.”

He added that Alcoa is Western Australia’s largest user of natural gas in its alumina refineries.

Coleman also noted the new supply will provide energy consumers with even more choice in an already robust and well-supplied market.
