Signal Why the $2.5 billion Tomago aluminium deal is no ordinary bailout

Summary

Australia's federal government and the New South Wales government jointly announced a A$2.5 billion (about $1.8 billion) support package on August 13, 2026 for Tomago Aluminium, the country's largest aluminium smelter, majority-owned by Rio Tinto (51.55%) alongside Gove Aluminium Finance and Norsk Hydro, according to The Conversation. Under the deal, Tomago itself will invest $1.1 billion, including $100 million for decarbonization initiatives, and will enter a 10-year power purchase agreement beginning December 31, 2028 when its current electricity contract expires, underpinning nearly 3 gigawatts of new renewable generation and firming capacity. Tomago has separately stated targets of 50% renewable electricity by 2030 and 100% by 2035. The smelter, which produces up to 590,000 tonnes of aluminium annually (about 40% of Australia's total production), faced closure risk because electricity costs represent around 40% of its total costs and account for 12% of New South Wales' total electricity demand, the largest single load in Australia. The smelter directly employs about 1,000 workers and supports an estimated 5,000 indirect jobs. The deal follows a similar March 2026 government support package for Rio Tinto's Boyne aluminium smelter in Queensland.
