Marking a new era in Australia’s energy transition, Hazelwood is the first retired coal-fired power station to host a battery storage system in Australia and represents a key moment in repurposing former thermal assets for renewable energy technologies.

Jointly funded and developed by ENGIE and Eku Energy, the 150MW/150MWh Hazelwood BESS is Australia’s largest privately funded utility-scale battery. Fluence supplies, operates, and maintains the facility for the partnership and it is the first project in Australia to use Fluence’s Gridstack product to provide secure and reliable energy in Victoria and support the energy transition.

Minister for Energy & Resourcesin Victoria The Hon. Lily D’Ambrosio MP said, “Victoria is leading the nation in delivering battery and energy storage projects, with our ambitious energy storage targets ensuring that Victoria continues to attract industry investment and collaboration opportunities like this. The Latrobe Valley has been the home of Victoria’s energy generation for decades and new investment in technologies like energy storage will help solidify its role in our renewable energy future.”

ENGIE ANZ CEO Rik De Buyserie said, “ENGIE’s delivery of the Hazelwood battery  is part of our commitment to building long-term, reliable assets that play a key role in the future of Australia’s energy transition. With its access to transmission and available space at site, Hazelwood is the perfect location for an asset that can grow in depth and duration, increasing the hosting capacity for renewables.”

The Hazelwood battery has the capacity to store the equivalent of an hour of energy generated from the rooftop solar systems of 30,000 homes. It will play a critical role in increasing renewable energy capacity in Victoria while delivering essential system services to the grid. The Hazelwood Power Station was built in the 1960s and closed in 2017 after 50 years of service, in line with ENGIE’s global strategy to be Net Zero carbon by 2045.
