5 February 2021 CEP.Energy, a company chaired by former NSW Labor premier Morris Iemma, has announced plans to build what it says will be the “world’s biggest battery” – 1,200MW – at the industrial centre of Kurri Kurri in the Hunter Valley, right where the Morrison government wants to build its own gas-fired generator. The CEP plans follow on from the announcement last October that the company would build a network of industrial-scale rooftop solar and battery storage installations, totalling up to 1,500MW. These plans have now been expanded to encompass grid-scale batteries, with the 1,200MW Kurri Kurri battery – there is no word yet on the storage duration – to be part of a network of four big grid-scale batteries across the country with a total capacity of 2,000MW.
