Synergy's 500-MW Battery: Powering Western Australia's Future
- Synergy powers ahead with construction of massive Collie Battery Energy Storage System, supporting Western Australia's green energy goals with cutting-edge technology.
Synergy, a state-owned energy retailer in Western Australia, has begun construction on a 500-MW/2,000 MWh Collie Battery Energy Storage System, which will be one of the largest in Australia. The grid-scale battery will be located near a coal-fired station set to close by 2027, supporting the state's decarbonisation efforts. The project, costing AUD 1.6 billion, is part of a state program to expand energy storage deployment and transition away from fossil fuels.
The battery, to be operational by the end of 2025, will consist of two 250-MW/1,000 MWh phases, with the first phase including 650 EnerC Plus battery units from CATL. Synergy aims to add 3 GWh of energy storage by 2025, with the company already operating the 100-MW Kwinana Battery Stage One and working on a 250-MW expansion set to be completed in late-2024.
