Rio Tinto Secures Tomago Aluminium Future with Long-Term Power Deal Until 2038

Key Facts

In a move reflecting the strategic importance of Australia's industrial stability, Rio Tinto has welcomed a long-term agreement to secure the operational future of the Tomago Aluminium smelter until 2038. The agreement, reached with the Australian and New South Wales governments, ensures the facility will receive internationally competitive and reliable power supplies. This deal provides 12 years of operational certainty for the nation's largest aluminium smelter, addressing critical energy security needs.

The agreement aims to mitigate energy cost volatility for Rio Tinto’s regional interests, as aluminium smelting profitability is highly sensitive to electricity pricing. Per market data, RIO shares closed at $101.91 (close August 10, 2026), while the London-listed RIO.L stood at 7,510 pence on the same date. Securing long-term power contracts is a key driver for maintaining asset stability and protecting margins within the capital-intensive mining sector.
