Perth contractor awarded $50m for big battery connection

The big battery storage system in Collie, WA — slated to be one of Australia’s largest — has taken another step forward with the awarding of a $50 million contract to Perth-based company SCEE Electrical to help build the link to the power grid.

The 500 MW/2000 MWh battery is due to be completed in late 2025.

In addition to this most recent contract, SCEE Electrical is already undertaking $160 million worth of civil, electrical and major equipment installation works on the project.

The new works will deliver a 330 kV switchyard and substation, as well as supporting ancillary buildings and equipment to connect the Collie battery to Western Power’s network.

Acting Energy Minister Dr Tony Buti said it was great news that a Perth-based company was playing a leading role in bringing the project to fruition.

“Congratulations to SCEE Electrical for being awarded this contract that will deliver more jobs for Western Australians as well as support the local economy,” Buti said.

“The Collie battery is crucial to WA’s sustainable energy future and it will play a major role in providing better energy outcomes for households and businesses.”

Battery energy storage systems collect excess energy from rooftop solar and wind farms during the day and release it when needed in the evening and at peak times.

With state-owned coal-fired power stations due to be retired by 2030, the battery is part of the WA Government’s $2.3 billion plan for its energy provider, Synergy, to deliver new battery storage to support renewable energy integration and grid stability.

“Collie will be home to one of the largest battery storage systems in the world once this project is complete,” said Collie MLA Jodie Hanns.

“It means Collie will continue to play a vital role in the energy system for decades to come, having powered WA for over a century.”
