WA Government Trials Long-Duration Vanadium Flow Battery

The Western Australian Government is piloting a vanadium flow battery in Kununurra to test its effectiveness in the Kimberley’s unique climate. With a capacity of 78KW and 220KWh, the battery is designed for temperature resilience and extended energy storage, ideal for the region's needs.

The project aims to provide Horizon Power with insights into integrating long-duration storage into its microgrids and off-grid systems. It complements existing large-scale batteries in Kwinana and Collie, which manage excess rooftop solar power.

VSUN Energy, a subsidiary of Australian Vanadium, is supplying the battery and will collaborate on system testing for 12 months.

Energy Minister Reece Whitby emphasized the role of battery storage in supporting the state’s clean, reliable, and affordable energy transition.

Kimberley MLA Divina D’Anna hailed the initiative as a step toward securing affordable and resilient power for regional communities.
