All 640 batteries and 160 inverters are now in place, marking the completion of installation works on the Collie Battery Energy Storage System in Western Australia.
Synergy’s Collie Battery Energy Storage System is set to become one of the biggest batteries in Australia. When completed, the 500-megawatt battery with 2000 megawatt hours of energy storage will be able to power around 785,000 homes.
The Collie battery, situated about 200 kilometres south-east of Perth, will help to replace coal-fired power generation with renewable energy generation infrastructure and energy storage solutions.
The battery is Synergy’s third grid-connected battery, with two existing battery energy storage systems in Kwinana (KBESS1 and KBESS2) supporting the reliability of Western Australia’s energy system.

The battery is on track for completion later this year. Construction and installation begun in May last year, with commissioning works now commencing.
Energy and Decarbonisation Minister Amber-Jade Sanderson said Western Australia is paving a clear path for the clean energy transition, as well as job creation.
“Synergy’s Collie battery will play a critical role in Western Australia achieving net zero emissions by 2050 and delivers on our commitment to power WA with cleaner, reliable and affordable energy,” Sanderson said.
“It is exciting to see how Synergy’s Collie battery is progressing in time for summer.”
