On April 16, 2025, the Blyth Battery Energy Storage System (238.5MW/477MWh) in South Australia officially went live. Developed by Neoen Australia and built in partnership with NHOA Energy (Italy) and Elecnor (Spain), the project utilizes over 900 battery units from China’s CATL and inverters from Spain’s Power Electronics.
With a total investment of AUD 337 million (approx. RMB 1.7 billion), the battery plays a pivotal role in South Australia’s transition to 100% renewable energy. Its key functions include:
- Providing system strength and inertia typically supplied by coal-fired plants;
- Supporting stable output from Neoen’s Goyder South Stage 1 wind farm;
- Delivering 70MW of baseload renewable power to BHP’s Olympic Dam under a long-term contract.
Connected via ElectraNet’s 275kV transmission system, the Blyth battery uses advanced grid-forming inverter technology to simulate traditional generators, enhancing grid stability in a renewable-dominant environment.
Louis de Sambucy, CEO of Neoen Australia, stated:
“This is a major milestone for South Australia’s energy storage future. Thanks to NHOA and Elecnor for delivering on time and on budget.”
The project also received AUD 17 million in funding from the Australian Renewable Energy Agency (ARENA), reinforcing its strategic importance.
