TOKYO, Oct. 14, 2026 /PRNewswire/ — Trina Storage, the energy storage business unit of Trinasolar, has been selected to supply the battery energy storage system (BESS) for the 50MW / 196MWh AEJ Nozu Battery Energy Storage System project in Oita Prefecture, Japan.
Located in Nishihata, Nozu Town, Usuki City, the project was awarded under Japan’s FY2023 Long-Term Decarbonization Auction and is scheduled for completion in the third quarter of 2028. Trina Storage will supply its Elementa 2 Pro 5MWh battery energy storage solution for the project.
The Nozu Project adds to Trina Storage’s growing track record in Japan’s utility-scale energy storage market. As deployment of grid-scale battery storage expands in the country, Trina Storage has established local capabilities to support projects from system configuration and technical consultation through delivery coordination and after-sales service.
Through its team in Japan, Trina Storage works closely with customers and project partners to address local technical and project requirements, providing support throughout the project lifecycle. This local capability is complemented by Trina Storage’s global experience in battery cell technology, system integration and utility-scale energy storage deployment.
Dr. Leo Zhao, Head of Energy Storage (APAC), Trina Storage, said, "We are pleased to support Japan’s growing renewable energy portfolio through the AEJ Nozu Battery Energy Storage System project. With Trinasolar’s longstanding experience in solar and Trina Storage’s growing presence in utility-scale energy storage, we see significant opportunities to support Japan’s evolving energy needs. For Nozu and other projects in Japan, our focus is on combining advanced technology with strong local capabilities."
Trina Storage is also supplying a 160MWh utility-scale BESS project in the Kyushu region, adding to its growing project track record in Japan. In September, it also signed an MoU with AMP-lify for approximately 1GWh of grid-connected BESS projects in Japan, featuring the latest Elementa 3 series. The MoU agreement, together with projects like Nozu, reflects Trina Storage’s continued expansion in Japan as demand for utility-scale energy storage grows.
