To help support energy resilience in the Goldfields region and power a more diverse and resilient local economy, the State Government has committed $150 million towards the establishment of the Kalgoorlie Vanadium Battery Energy Storage System (VBESS).
The 50 megawatt/500 megawatt-hour battery will help achieve the State Government’s objectives to:
- reinforce power system security and reliability in Kalgoorlie and the Eastern Goldfields;
- support the adoption of long-duration energy storage technologies in WA; and
- catalyse the development of the local vanadium industry.
Stage One of the Expression of Interest (EOI) process was a market sounding exercise completed earlier in 2026. Through the Department of Energy and Economic Diversification, the State Government is requesting Proposals to deliver the VBESS facility and invest in the development of the local vanadium supply chain.
Stage Two of the EOI process is now open and will run until 4:00pm (AWST) Monday, 20 July 2026.
Proposals must comply with the eligibility requirements and address evaluation criteria outlined in the Proposal Guidelines.
Proposals should be submitted via email to VBESS@deed.wa.gov.au.
Proposals will be evaluated with the aim of selecting a Preferred Proponent to commence commercial negotiations with in the second half of 2026.
