Australia’s energy transition gained significant momentum this week with the announcement of a landmark A$2.5 billion deal between the federal and New South Wales governments and global mining giant Rio Tinto. The agreement, unveiled today, August 13, 2026, will see the Tomago aluminium smelter, the nation’s largest, transition to 100% renewable energy by 2033. This substantial investment aims to safeguard nearly 3,000 jobs while dramatically reducing industrial emissions in NSW.
The deal, publicly confirmed by Prime Minister Anthony Albanese and NSW Premier Chris Minns at the Tomago site near Newcastle, provides a 10-year below-market power supply guarantee. This critical support will commence in December 2028, following the expiration of the smelter’s current coal-focused electricity contract with AGL. The commitment underpins the development of almost 3,000 megawatts of new renewable and ‘firming’ capacity within NSW, a volume exceeding that of a large coal-fired power station.
Aluminium production is an energy-intensive process, making smelters highly vulnerable to fluctuations in electricity prices. This vulnerability has driven similar government interventions in the past, including A$2 billion for Rio Tinto’s Boyne aluminium smelter in Queensland and A$2.4 billion for steelworks in Whyalla, South Australia. The Tomago agreement is the latest in a series of strategic federal packages designed to ensure the continued operation and decarbonisation of Australia’s critical heavy industries.
“If this exciting record‑breaking year demonstrates anything, it is the power of working with committed and innovative co‑investors to supercharge the reach and impact of CEFC capital.” – Ian Learmonth, outgoing CEFC Chief Executive, August 13, 2026.
The federal government’s Clean Energy Finance Corporation (CEFC) also announced this week, on August 13, 2026, that it committed a record A$9.1 billion in the financial year ending June 30, 2026. This figure surpasses the previous year’s A$4.7 billion and represents over a third of the CEFC’s total commitments since its inception in 2012. A significant portion of this, A$7.2 billion, was channelled through the Rewiring the Nation Fund, including A$3.8 billion specifically for Stage 1 of the Marinus Link, a 750MW undersea and underground electricity cable connecting Tasmania to mainland Australia. This broader federal investment underscores the government’s commitment to large-scale infrastructure projects vital for grid stability and renewable energy integration, which indirectly supports initiatives like the Tomago deal.
For the Tomago smelter, the transition to 100% renewable energy is projected to cut its annual greenhouse gas emissions by 7.1 million tonnes, equivalent to approximately 1.5% of Australia’s total annual climate pollution. This move is not only an environmental victory but also a significant economic one, securing 1,000 direct jobs at the smelter and an additional 2,000 indirect jobs across the supply chain.
Prime Minister Albanese highlighted the deal’s dual benefits: “This agreement is about securing the future of Australian manufacturing and Australian jobs, while taking decisive action on climate change. It shows that responsible climate policy can go hand-in-hand with a strong economy and secure regional employment.”
NSW Premier Minns echoed this sentiment, emphasising the strategic importance for the state: “NSW is leading the charge in renewable energy, and this partnership with Rio Tinto ensures a vital industrial asset remains competitive and a major employer for decades to come. The new renewable capacity this deal underpins will also contribute significantly to NSW’s overall energy security.”
Rio Tinto Aluminium and Lithium Chief Executive, Jérôme Pécresse, stated that the agreement provides a pathway to “long-term, cost-competitive, low-carbon power” for the smelter. This strategic shift is crucial for global competitiveness as industries face increasing pressure to decarbonise their supply chains. The deal reflects a growing trend where governments are actively partnering with heavy industry to de-risk the transition to clean energy, ensuring that high-value manufacturing remains onshore. This approach aims to stabilise wholesale electricity prices by increasing reliable renewable generation, a benefit that can ultimately flow through to all consumers.

The development of new renewable and firming capacity is essential to support such large-scale industrial loads and maintain grid reliability as coal-fired power stations retire. The Australian Energy Market Operator (AEMO) in its 2026 Integrated System Plan (ISP) reaffirmed that renewable energy, firmed with storage and backed by gas, is the least-cost way to ensure secure and reliable electricity to consumers through to 2050. The Tomago deal directly contributes to this vision by stimulating the investment needed in new generation. The scale of the investment in new capacity will also influence the overall market dynamics for energy providers.

This A$2.5 billion commitment not only secures the future of a critical industrial operation but also accelerates Australia’s path towards its ambitious net-zero emissions targets by providing a concrete example of how large-scale industrial decarbonisation can be achieved through strategic government and industry collaboration. It sets a precedent for other energy-intensive industries facing similar transition challenges across the nation.
