Australia’s largest aluminium smelter, Tomago, located near Newcastle, New South Wales, is set to transition to 100 per cent renewable energy by 2033, following a significant AUD $2.5 billion subsidy deal struck between resources giant Rio Tinto, the federal government, and the New South Wales government. Announced on Thursday, 13 August 2026, by Prime Minister Anthony Albanese and NSW Premier Chris Minns, the agreement is designed to prevent the potential closure of the critical industrial facility and underpin a substantial boost in the state’s renewable energy capacity.
The deal provides a 10-year below-market power supply guarantee for the Tomago smelter, commencing after its existing coal-focused electricity contract with AGL concludes in December 2028. This intervention is crucial for maintaining the smelter’s operations, which support nearly 3,000 direct and indirect jobs in the Hunter region.
Decarbonising Heavy Industry: A National Imperative
The Albanese government has positioned this agreement as a vital step in decarbonising Australia’s heavy industry, aligning with national emissions reduction targets. The transition of the Tomago smelter to clean energy is projected to cut its annual greenhouse gas emissions by 7.1 million tonnes, which accounts for approximately 1.5 per cent of Australia’s total annual climate pollution.
“This deal provides Tomago with a pathway to long-term, cost-competitive, low-carbon power, securing its future and thousands of jobs,” said Jérôme Pécresse, Rio Tinto Aluminium and Lithium’s chief executive.
The federal government highlighted that the deal would underpin nearly 3,000 megawatts (MW) of new renewable and “firming” capacity within New South Wales. This new capacity will be drawn from projects already in the development pipeline, including wind farms and solar installations backed by batteries, spread across the state rather than concentrated solely in the Hunter Valley. The integration of battery storage will be critical for providing grid stability and ensuring a reliable power supply for the smelter, reflecting a broader trend towards leveraging energy storage for industrial load management.
Broader Policy Context: Government Support for Key Industries
This AUD $2.5 billion commitment for Tomago is the latest in a series of substantial government support packages aimed at ensuring the continued operation and decarbonisation of Australia’s major industrial facilities. The government has previously committed AUD $2 billion for Rio Tinto’s Boyne aluminium smelter in Queensland and AUD $2.4 billion for steelworks in Whyalla, South Australia. These investments underscore a strategic policy approach to support energy-intensive industries through the energy transition, mitigating job losses and maintaining economic output.
| Project | Location | Government Support | Decarbonisation Goal | Jobs Impact (Approx.) |
|---|---|---|---|---|
| Tomago Aluminium Smelter | Newcastle, NSW | AUD $2.5 billion | 100% renewables by 2033 | 3,000 |
| Boyne Aluminium Smelter | Queensland | AUD $2 billion | Decarbonisation pathway | Not specified |
| Whyalla Steelworks | South Australia | AUD $2.4 billion | Decarbonisation pathway | Not specified |
Such financial commitments are designed to bridge the gap between existing fossil-fuel-based power contracts and the development of new, cost-competitive renewable energy sources. The challenge for these industries lies in securing firm, reliable, and affordable renewable power at the scale required for continuous operations, such as aluminium smelting. The deal reflects a recognition that while firmed renewable energy is becoming the cheapest generation option, the transition requires strategic government intervention and investment to accelerate new capacity and transmission infrastructure.
Implications for NSW Energy Grid and Consumers
The commitment to develop almost 3,000 MW of new renewable and firming capacity in NSW will have broader implications for the state’s energy grid. Increased renewable generation, especially when paired with battery storage, enhances grid stability and reduces reliance on older, less reliable coal-fired power stations. This could contribute to lower wholesale electricity prices in the long term by increasing the supply of cheaper, clean energy. Households and businesses across NSW could indirectly benefit from a more stable and cost-effective energy market.

The introduction of new battery storage as part of this capacity build-out also opens opportunities for greater grid flexibility. As more large-scale batteries come online, they can participate in services that support grid stability, potentially reducing peak demand charges and improving overall system resilience. These developments mirror the growing importance of distributed energy resources and the potential for homeowners with batteries to participate in schemes like Virtual Power Plants (VPPs) to further benefit from grid support.

The Tomago deal highlights the complex interplay between industrial policy, energy security, and climate targets. While significant taxpayer funds are involved, the aim is to secure a future for essential industries within a decarbonised economy, preventing economic disruption and leveraging private investment in new clean energy infrastructure.
Looking Ahead
The focus now shifts to the delivery of the new renewable and firming capacity by 2033. The success of this transition will serve as a critical case study for other energy-intensive industries in Australia and globally, demonstrating the feasibility and challenges of decarbonising hard-to-abate sectors through strategic government and industry partnerships. The agreement underscores the Albanese government’s ongoing commitment to its energy transition agenda and the role of targeted policy interventions in achieving ambitious climate goals while supporting regional economies.
