en.Wedoany.com Reported - On August 13, the Australian federal government and the New South Wales state government announced a total of A$2.5 billion (approximately US$1.76 billion) in ten-year support for the Tomago Aluminium smelter, helping Australia's largest aluminium smelter continue operations after its existing electricity supply contract expires at the end of 2028.
The government support package will commence in 2029, with funding shared between the Australian federal government and the New South Wales state government. Under the agreement, Tomago Aluminium will enter into a ten-year power purchase agreement covering the period through 2038, and will source 100% renewable electricity from 2033. The company's existing electricity contract expires on December 31, 2028.
Tomago Aluminium will also invest A$1.1 billion in the smelter between now and 2038, primarily for capital upgrades and major maintenance, including A$100 million for decarbonisation projects. The smelter will also continue participating in demand response for the New South Wales grid, reducing electricity load during periods of power system stress. Australian Industry Minister Tim Ayres said the associated electricity arrangements will drive approximately 3 gigawatts of new generation supply.
The Tomago smelter is located approximately 13 kilometres west of Newcastle in New South Wales, with a maximum annual aluminium output of around 590,000 tonnes, accounting for nearly 40% of Australia's annual primary aluminium production. The smelter requires approximately 950 megawatts of continuous electricity, representing about 12% of New South Wales' electricity demand, making it the state's largest single electricity-consuming facility.
Tomago Aluminium is owned 51.55% by Rio Tinto, 36.05% by Gove Aluminium Finance, and 12.4% by Norsk Hydro. The smelter employs approximately 1,000 staff and 200 full-time equivalent contractors, and supports around 5,000 indirect jobs in the Hunter region supply chain.
In October 2025, Tomago Aluminium stated it was considering ceasing operations due to the failure to secure an affordable electricity solution beyond 2028. In December of the same year, the Australian federal government and the New South Wales state government proposed a long-term fixed-price electricity support pathway. This agreement further confirms government funding, corporate investment, power purchase duration, and renewable energy supply arrangements.
According to data disclosed by Rio Tinto, once the Tomago smelter fully transitions to renewable energy from 2033, it will reduce approximately 7.1 million tonnes of Scope 1 and Scope 2 operational carbon emissions annually. The new ten-year power purchase arrangement will take effect after the existing contract expires at the end of 2028.

IV. Key Business Opportunities for Chinese Suppliers
1. Critical Equipment Upgrades for the Aluminium Smelter
Tomago operates 3 potlines with approximately 840 electrolytic cells. Long-term operation and asset life extension may generate the following demand:
(1) Electrolytic cell shells and structural components
(2) Busbars and flexible connection components
(3) Cathodes, anodes and conductive materials
(4) Electrolytic cell insulation materials
(5) Anode changing equipment

VII. Market Entry Strategy for Chinese Suppliers
It is recommended to adopt an "equipment export + Australian local service" model rather than simply quoting directly from China.
Priority Actions:
Prepare English-language corporate qualifications, Australian project case studies and aluminium industry track records.
Clearly identify compliance with AS/NZS, IEC and mining and industrial safety standards.
Identify Australian local installation, commissioning and after-sales partners.
Enter the supply chain through Tomago's supplier registration and contractor management processes.
Prioritise contact with on-site technical demand departments or existing approved contractors.
For energy storage, renewable energy and grid connection equipment, focus on developing project developers and EPC contractors rather than only contacting Tomago.
Prepare spare parts inventory, fault response times and long-term maintenance plans.
For high-voltage, lifting, fire protection and pressure equipment, confirm Australian certification and licensing requirements in advance.
VIII. Key Supplier Qualification Considerations
Tomago's supplier evaluation may cover:
Environment, health and safety management
Corporate social responsibility
Personnel and technical resources
Production facilities and equipment capabilities
Quality management systems
Commercial terms
Communication and project management capabilities
Continuous improvement capabilities
Technical and R&D capabilities
Insurance and Australian local compliance
Procurement necessity justification from on-site business departments
Submitting only a general product catalogue is usually insufficient to enter the supplier system. More effective materials are English-language technical proposals addressing specific equipment issues, application case studies from similar aluminium smelters, and Australian local delivery plans.
