Developers plan to build what they say will be the world’s biggest large-scale battery in the New South Wales Hunter Valley, the latest in a flurry of major energy storage projects announced for the national electricity grid.
CEP Energy said its $2.4bn battery at Kurri Kurri, north-west of Newcastle, would have a power capacity of up to 1,200 megawatts – about eight times greater than the battery at Hornsdale in South Australia, which was the biggest when it began operating in 2017.
