Power Electronics will deliver 72 inverters for the Kwinana battery and 160 inverters for the Collie battery.

Kwinana Battery Stage Two will provide 200MW of power with 800MWh of energy storage. Construction started on Kwinana Battery Stage Two in June and is estimated for completion at the end of 2024. The Collie battery will be the biggest in the state, providing 500MW of power with 2,000MWh of storage.

The batteries will support more renewables by storing wind and solar energy generated during the day and delivering it back to the system during high-demand periods.

Western Australian Premier Roger Cook said, “These contracts, worth more than $1 billion, represent a major and important investment by our government into WA’s cleaner, reliable and affordable energy future.

“Battery energy storage systems will play a key role in our decarbonisation plans, storing excess renewable energy generated in the day and discharging during times of high demand.”
