Four big batteries bound for Western Australia have been successful under the federal government’s Capacity Investment Scheme (CIS).
The successful clean dispatchable capacity projects will be able to deliver 654MWh of energy—more than the tender size of 500MW. This is enough to supply the peak electricity load for over 600,000 homes in WA for four hours.

Projects are scheduled to be operational by October 2027 and align with WA’s unique Reserve Capacity Mechanism.
The successful projects include:
- 324MW Boddington Giga Battery operated by PGS Energy, 120km south-east of Perth
- 100MW Merredin Big Battery operated by Atmos Renewables, 230km east of Perth
- 150MW Muchea Big Battery operated by Neoen, 43km north-east of Perth
- 80MW Waroona Renewable Energy Project—Stage 1 operated by Frontier Energy, 120km south of Perth.
The projects will provide important back up to Western Australia’s south-west grid including Perth, ensuring reliability particularly at times of peak demand.

This is the first CIS tender in WA, and follows successful tenders in the eastern states. The next WA tender is scheduled for mid-2025.
Western Australia is already set to become home to Australia’s biggest battery—the 560MW/2,240MWh Collie battery being developed by Neoen.
