Construction has begun on Synergy’s Collie battery energy storage system, which will be one of the biggest grid-scale batteries in Australia.

  • Construction begins on 500 megawatt/2000 megawatt hour Collie battery
  • Grid-scale battery to be one of the biggest in the world once complete
  • Project will support decarbonisation and Collie jobs

Construction has begun on Synergy’s Collie battery energy storage system, which will be one of the biggest grid-scale batteries in Australia when complete and will provide significant security to Western Australia’s main power system.

The battery, which will have a 500 megawatt/2000 megawatt hour capacity, will be funded as part of the State Government’s commitment to expand battery storage throughout WA.

Synergy’s batteries are already playing a critical role in meeting peak demand, with Kwinana Battery Stage One providing power to the South West Interconnected System since it was completed in May 2023.

“This is an exciting milestone for Western Australia’s decarbonisation journey. Synergy’s ground-breaking project is significant for the Collie community and will help local workers and families as Synergy seeks to exit coal-fired power by 2030,” says Energy Minister Reece Whitby.

“When complete, this battery will support reliability and more renewable energy on WA’s main electricity grid,” says Energy Minister Reece Whitby.

Kwinana Battery Stage Two is under construction and due to be completed in late-2024.

“The build of Australia’s biggest battery right here in Collie marks a significant point in the energy transition,” says Collie-Preston MLA Jodie Hanns.

“Collie has been at the heart of WA’s energy system for decades and will continue to play an important role in the future,” says Collie-Preston MLA Jodie Hanns.

“I’m delighted that a local business has been selected to be part of this project, creating local jobs as part of the ongoing support for our community by the Cook Labor government,” says Collie-Preston MLA Jodie Hanns.

Collie-based earthworks and rehabilitation specialists Cardinal Contractors has been awarded the contract to complete site preparation earthworks for the battery facility, with up to 500 jobs expected to be created at the peak of construction.

The battery is expected to be completed by the end of 2025.

Large-scale batteries provide long-term system stability and support the uptake of more renewables, with Synergy planning to build 3 gigawatt hours of storage by 2025.
