Western Australia Vanadium Battery Plan Targets Grid Storage and Local Supply Chain

Vanadium Battery

Western Australia vanadium battery plans are moving forward as the state government offers A$150mn to support a 50MW battery energy storage system in Kalgoorlie. The project is intended to strengthen energy security in Kalgoorlie and the Eastern Goldfields as the state exits coal-fired power.

Western Australia vanadium battery funding will be awarded through a competitive proposal process. Bids are due by 20 July 2026, with evaluation expected from July and results to be announced later in the year.

Western Australia vanadium battery proposals must also show how they will support the local vanadium supply chain. That condition gives the project industrial significance beyond electricity storage alone.

The plan connects grid reliability, renewable integration and critical minerals development. It also supports Western Australia’s wider Made in WA policy, which aims to build more local manufacturing and clean-energy supply chain capacity.

Kalgoorlie Storage Project Supports Coal Exit

The 50MW Kalgoorlie project is part of Western Australia’s transition away from state-owned coal-fired generation. The government pledged in 2022 to close all state-owned coal plants by 2030.

Several major coal units are already scheduled for closure. Synergy’s Muja C, Muja D and Collie power station will be retired in stages between 2025-26 and 2029-30.

Battery storage is expected to replace part of the capacity and flexibility lost from coal. This is critical because renewable generation requires storage assets that can manage intermittency, stabilise the grid and support peak demand.

Kalgoorlie and the Eastern Goldfields are particularly important because mining regions need reliable electricity. Power disruptions can affect processing plants, mine operations, logistics and regional industrial development.

The government expects more than 1,200MW of new generation and storage to enter the South West Interconnected System in 2025-26 and 2026-27. A further 1,000MW is expected in 2027-28.

The scale of the pipeline shows that Western Australia is not treating storage as a marginal add-on. It is becoming core infrastructure for the state’s post-coal power system.

Vanadium Supply Chain Becomes Part of Energy Policy

The request for proposals is notable because it links battery deployment with local vanadium supply chain investment. This turns the project into both an energy storage initiative and a critical minerals development tool.

Vanadium batteries are attractive for long-duration grid storage because they can offer long cycle life and are suited to stationary applications. They do not compete directly with lithium-ion batteries in every market, but they can serve grid use cases where durability and duration matter.

Western Australia has already invested heavily in battery storage. In 2023, the state awarded A$1bn to support the 500MW Collie battery energy storage system and the 200MW Kwinana battery energy storage system.

The state’s 2025-26 budget also included A$50mn for a local battery manufacturing programme under the Made in WA policy. That aligns with the new vanadium battery proposal, which asks bidders to contribute to regional, economic and community outcomes.

Federal support is also backing Western Australia’s storage buildout. Four lithium-ion battery projects are being partly underwritten through the Capacity Investment Scheme, adding 2.6GWh of storage capacity from late 2027.

This creates a mixed battery landscape. Lithium-ion will remain important for large-scale storage, but vanadium could give Western Australia a route to build a differentiated local supply chain around its own mineral base.

The strategic test will be whether the Kalgoorlie project can move beyond demonstration value. It must prove cost competitiveness, operational reliability and real local supply chain development.

The Metalnomist Commentary

Western Australia is using grid storage procurement to create demand for a local vanadium industry. That is the right industrial logic: critical mineral supply chains need committed end-use demand, not just resource potential.
