Tomago Aluminium will invest A$1.1 billion (real terms) in the smelter between now and 2038, including A$100 million for decarbonisation initiatives.

Emissions Reduction Impact

Second Major Smelter Secured
Follows a March 2026 agreement for the Boyne smelter, meaning Australia's two largest aluminium smelters now have secured long-term, cost-competitive low-carbon power.
Analysis · RIO · Energy & Transportation
Rio Tinto's 51.55%-owned Tomago Aluminium joint venture has locked in a 10-year power purchase agreement with the Australian and NSW governments, securing electricity supply through 2038 with 100% renewable sources from 2033. The deal removes a major operational risk for Australia's largest aluminium smelter, which produces nearly 40% of the country's aluminium, and supports A$1.1 billion of investment including A$100 million for decarbonisation. This follows a similar March 2026 agreement for the Boyne smelter, meaning both of Australia's largest smelters now have secured long-term, cost-competitive power beyond their current contracts.
