The Clean Energy Finance Corporation (CEFC) is backing Neoen’s Collie Battery Stage 1 in Western Australia. The aim is to strengthen support for the South West Interconnected System (SWIS) as the state’s clean energy transition gathers pace. The 219 MW Collie Battery is the first WA big battery to be financed by the CEFC and continues its leading role in accelerating the delivery of large-scale energy storage. The $55 million investment is part of Neoen’s portfolio financing, which includes eight clean energy assets spanning solar, wind and battery storage across 5 states with a combined generation capacity of some 1.5 GW.
