Synergy has awarded a $50 million contract for the construction of the switchyard works for its Collie BESS project. 

Under the contract, Perth-based company SCEE Electrical will deliver a 330kV switchyard, a substation, and support ancillary buildings and equipment to connect the Collie BESS to Western Power’s network. 

The 500MW/2000MWh Collie battery is due to be completed in late 2025 and will become one of the biggest battery energy storage systems in Australia. 

SCEE Electrical is already undertaking $160 million worth of civil, electrical, and major equipment installation works for the project.  

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 Western Australian Government has committed $2.3 billion for Synergy to deliver new battery storage to support renewable energy integration and grid stability. 

Acting Western Australian Minister for Energy, Tony Buti, said, “The Cook Government is committed to building one of the biggest battery systems in the world and it’s great news that a Perth-based company is playing a leading role in bringing this 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. 

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

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

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

“As we move to renewable energy and battery storage, this project adds to the legacy of a community who is committed to playing its role in the future energy needs of the state.”
