Rio Tinto secures 10-year renewable power agreement for Tomago Aluminium through 2038, anchoring A$1.1B smelter investment.

Rio Tinto has secured a 10-year power purchase agreement (PPA) for Tomago Aluminium, Australia's largest smelter, through 2038 with 100% renewable power from 2033 onwards. The agreement requires A$1.1 billion in smelter investment through 2038, including A$100 million for decarbonisation, and reduces Scope 1 and 2 operating carbon emissions by 7.1 million tonnes per year once renewable sourcing is complete. This follows a March 2026 agreement for Boyne Aluminium and consolidates Rio Tinto's control over two of Australia's largest integrated aluminium supply chains amid global energy-transition demand.

Rio Tinto is a global diversified mining and metals group operating across iron ore, aluminium, copper, and minerals segments. The company extracts, processes, and markets commodities essential to industrial production, energy transition, and construction.
