Rio Tinto Seeks Support for Australian Aluminium Smelter

Australian Al smelter

Power Costs Challenge Aluminium Operations

Rio Tinto is in talks with both the Australian federal government and the New South Wales (NSW) state government to secure support for its 600,000 t/yr Tomago aluminium smelter. The UK-Australian producer is renegotiating power purchase agreements to reduce costs, as energy expenses continue to rise across the state. Tomago accounts for about 12% of NSW’s total power use and plays a key role in grid stabilisation by adjusting production in line with electricity demand.

Officials confirmed discussions are underway, with NSW premier Chris Minns describing them as commercial negotiations. Industry and innovation minister Tim Ayers added that the government recognises Tomago’s strategic role but did not outline specific intervention measures. Meanwhile, energy minister Penny Sharpe acknowledged that soaring energy costs are straining many of the state’s energy-intensive industries.

Federal Incentives and Industry Outlook

Australia’s federal government has committed A$2bn ($1.3bn) under a low-emission production tax credit scheme, which will take effect in the 2028-29 fiscal year. The initiative aims to sustain aluminium production while encouraging cleaner processes. Rio Tinto has welcomed the scheme, calling it an important step toward maintaining Australia’s competitiveness in global aluminium markets.

Until the scheme is active, however, Rio Tinto must navigate high energy costs that threaten the viability of large-scale smelting operations. The company’s negotiations with power suppliers and government stakeholders will be critical in determining whether the Tomago smelter remains sustainable over the coming years.

The Metalnomist Commentary

Rio Tinto’s situation highlights the vulnerability of aluminium producers to volatile energy markets. While Australia’s tax credit scheme offers long-term relief, the immediate challenge is bridging the gap until 2028. The outcome at Tomago could set a precedent for how governments and power companies support energy-intensive industries under decarbonisation pressures.
