The CEFC committed up to A$50 million in project finance for South Australia’s landmark ‘big battery’, working alongside Neoen, ARENA and the SA Government to improve grid security and maximise the benefits of renewable energy. The CEFC finance is part of a 50 per cent expansion of the Hornsdale Power Reserve, the world’s largest grid-scale battery. The expansion, by leading international renewable energy developer Neoen, will provide an Australian-first large-scale demonstration of the potential for battery storage to provide the stabilising inertia services that are critical to the future integration of renewable energy.
