Energy storage and e-mobility company NHOA Energy has announced the commissioning of Blyth Battery, a 238.5MW/477 megawatt hours (MWh) energy storage system in South Australia.

Financed by international lenders, the project was developed in partnership with Elecnor for Neoen, a renewable energy company based in France.

The Blyth Battery supports Neoen’s Goyder South Stage 1 wind farm by providing 70MW of renewable baseload power, and offers additional services to the national electricity market.

Completed on schedule and within budget, the project meets all performance requirements from the Australian Energy Market Operator (AEMO) and ElectraNet.

Neoen Australia CEO Jean-Christophe Cheylus stated: “Blyth Battery is a great example of Neoen’s continuing commitment to grid stability and reliability in South Australia. We are proud to lead the state’s battery storage market and are excited to start supporting BHP under our innovative renewable energy baseload contract.

“We appreciate the dedication from and close collaboration with the teams at NHOA Energy & Elecnor, whose work has been essential in helping us meet this project milestone.”

A team of qualified professionals from NHOA Energy will manage the battery’s operations and maintenance under a long-term contract with Neoen, ensuring its sustained performance and availability.

NHOA Energy global managing director Lucie Kanius-Dujardin stated: “We fulfilled our performance commitment to Neoen and its lenders, on time and on budget. This is what matters, in a scenario where energy storage systems become the cornerstone of grid stability, security and an affordable and sustainable energy supply.

“The successful commissioning of Blyth Battery is a testament to the dedication and expertise of our team and partners, and to our ability to serve clients globally.”

In a related development, Neoen secured seven solar and agrisolar projects totalling 164 megawatts peak in France.

Thee projects, awarded by the French Energy Regulation Commission, enhance Neoen’s footprint in the ground-mounted solar sector, with a total capacity now exceeding 2.5GW in the country.
