The first stage of what will be Australia’s biggest battery project has been energised – little more than a year after securing its development contract – and will soon be in operation to help flatten the growing solar duck in Western Australia’s main grid.
The Collie battery is being built by Neoen in two stages, including a 219 MW/877 MWh first stage that was among the first winners of special contracts issued last year to soak up rooftop solar in the middle of the day and time shift it to the evening peak.
A second stage of the battery – even bigger at 341 MW and 1,263 MWh – won a similar contract in a new tender held earlier this year and will become the biggest battery in the country when complete at 560 MW and 2,240 MWh.
