Neoen Australia has begun construction of a big battery that is co-located with one of Australia’s biggest solar farms, the 440 megawatt Culcairn project near the town of the same name in New South Wales.

The battery, which will share the same grid connection as the solar farm, will have a power capacity of 215 megawatt (MW) with storage capacity of around 4.5 hours, or 963 megawatt-hours (MWh).

The Culcairn Solar Farm was officially powered up in May by project developer Neoen Australia, the local subsidiary of French renewable energy producer Neoen. Rated at 350 MW, or 440 MWp, Culcairn is Neoen’s second-largest solar asset, behind the 400 MW Western Downs solar farm in Queensland.

In a LinkedIn post on Tuesday, Neoen Australia said it was “especially proud of this asset” because it was the company’s “first ‘behind-the-meter’ battery at a solar farm!”

“This is possible thanks to the deep, technical expertise of our people and to their strong relationships in the industry and project community,” the post says. “We are ready to explore a new world of opportunities to continue supporting our customers, our communities, the market and Australia’s energy transition.”
