The Collie battery, with a capacity of 500MW and 2000MW hours, is set for completion in late 2025.  

It is poised to become one of the largest battery energy storage systems in Australia.  

WA Collie legislative assembly member Jodie Hanns said: “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.” 

The WA Government has allocated A$2.3bn for Synergy to deliver new battery storage solutions, which is expected to integrate renewable energy and enhance grid stability. 

This announcement comes shortly after the WA Government selected Brajkovich Demolition & Salvage to undertake the demolition of the former Stirling Towers complex this month.
