Rio Tinto PLCSecures power supply for Tomago smelter through 2038, ensuring continued operations and reducing emissions.

Rio Tinto-backed Tomago Aluminium has reached an agreement with Australia's federal and New South Wales governments designed to secure the future of the country's largest aluminium smelter through 2038. Under the arrangements announced Thursday, Tomago will enter into a 10-year power purchase agreement covering electricity supplies after its existing contract expires at the end of 2028, and the smelter is expected to transition to electricity sourced entirely from renewables from 2033. Tomago, located near Newcastle in New South Wales, is the state's largest electricity consumer and can produce as much as 590,000 metric tons of aluminium annually, representing almost 40% of Australia's production. The company will invest A$1.1 billion in real terms in the facility through 2038 as part of the agreement, including A$100 million allocated to decarbonisation projects. Rio Tinto said the switch to fully renewable electricity from 2033 is expected to cut Tomago's Scope 1 and Scope 2 operating emissions by 7.1 million metric tons annually. The agreement follows a March 2026 arrangement involving Rio Tinto and the Australian and Queensland governments that provided a pathway for the Boyne aluminium smelter in Gladstone to remain competitive beyond the end of its current electricity contract, giving Australia's two largest aluminium smelters pathways to longer-term, lower-carbon electricity supplies.
