Mining giant Fortescue has commenced construction on a 650MWh battery energy storage system at Cloudbreak in Western Australia’s Pilbara region, alongside the 690MW Turner River solar PV power plant.

Australia has emerged as the world’s third-largest utility-scale battery energy storage market, with 4.3GW of large-scale battery storage systems reaching financial close in 2025.

Utility-scale battery storage systems in Western Australia supplied 37.2% of peak demand on 9 May, marking one of the highest battery storage penetration levels recorded in an isolated grid globally.

The Australian government has announced the results of Capacity Investment Scheme Tenders 5 and 6 for WA, awarding contracts to 10 projects.

BESS in Australia’s NEM more than tripled their daytime-to-evening energy shifting in the first quarter of 2026, according to AEMO.

Australian mining giant Fortescue has accelerated its timeline for deploying 4-5GWh of battery energy storage systems (BESS) paired with 1.8GW of renewable energy generation, which it now expects to begin commercial operation by 2028.

Engineering firm UGL is progressing the construction of two battery energy storage systems (BESS) in Australia, totalling 2,125MWh.

James Costello, CEO of EORA Energy, argues that long-duration vanadium redox flow battery storage is critical to Western Australia’s decarbonisation efforts, particularly for remote mining operations.

RE Development Pty Ltd has submitted a development application for a 250MW/1,000MWh battery energy storage system (BESS) in Baldivis, Western Australia.

Australian Vanadium Limited has secured an exclusive partnership with Sumitomo Electric Industries for the 500MWh Kalgoorlie vanadium BESS.
