Perth contractor chosen for $50 million works for Collie battery

  • SCEE Electrical awarded $50 million contract at Synergy’s Collie battery
  • 500MW/2000MWh battery to be one of the biggest in the world when complete
  • Battery to support renewable energy integration and grid stability

Collie’s big battery storage system is taking another major step forward, with Perth-based company SCEE Electrical winning a $50 million contract to help build the link to the power grid.

Synergy has awarded the contract to construct the switchyard works to SCEE Electrical – which is already undertaking $160 million worth of civil, electrical, and major equipment installation works.

The new scope of works will deliver a 330 kilo volt switchyard, substation and support ancillary buildings and equipment to connect the Collie battery to Western Power’s network.

The 500 megawatt/2000 megawatt hour Collie battery is due to be completed late in 2025. It will be one of the biggest battery energy storage systems in Australia.

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

As stated by Acting Energy Minister Dr Tony Buti:

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

As stated by Collie MLA Jodie Hanns:

“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 WA 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.”
