Synergy secures planning approval for 2 GWh big battery
Australian utility Synergy has secured approval for its plan to build a 500 MW/2,000 MWh battery energy storage system in Western Australia.
Western Australia’s Regional Joint Development Assessment Panel has approved Synergy’s plans to construct a 500 MW, four-hour battery energy storage system near the coal town of Collie and has also provided a green light for infrastructure approvals to support a possible expansion to 1,000 MW/4,000 MWh.
The first stage of the proposed development will comprise the installation of two 250 MW/1,000 MWh ‘sub facilities’ featuring 656 battery enclosures, 164 inverters and up to four 330/33kV transformer units.
Synergy said the battery will help provide the state’s power grid with the capacity it needs to remain reliable and affordable as the state moves towards emissions-free power generation in 2030.
The government-owned energy generator and retailer has already completed construction of the 100 MW/200 MWh Kwinana battery energy storage system about 30 kilometers south of Perth and has started work on a new 200 MW/800 MWh big battery being built adjacent to that facility.
