Trina Storage to Deliver 196MWh Elementa 2 Pro System for AEJ Nozu BESS in Japan

The AEJ Nozu Battery Energy Storage System project, sited in Nishihata, Nozu Town, Usuki City in Oita Prefecture, Japan, will be equipped with Trina Storage's Elementa 2 Pro 5MWh battery energy storage solution, the company announced in Tokyo on Oct. 14, 2026.

Award Won Under FY2023 Long-Term Decarbonization Auction

The 50MW/196MWh project was secured under Japan's FY2023 Long-Term Decarbonization Auction and is scheduled for completion in the third quarter of 2028. Trina Storage is the energy storage business unit of Trinasolar.

Local Team Anchors Delivery Across the Project Lifecycle

To support the deployment, Trina Storage relies on capabilities established within Japan, covering system configuration, technical consultation, delivery coordination and after-sales service. The company's team in Japan works with customers and project partners to address local technical and project requirements throughout the project lifecycle.

This is complemented by the company's global experience in battery cell technology, system integration, and utility-scale energy storage deployment. Dr. Leo Zhao, Head of Energy Storage (APAC) at Trina Storage, said the company is pleased to support Japan's growing renewable energy portfolio through the AEJ Nozu 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," Zhao said. "For Nozu and other projects in Japan, our focus is on combining advanced technology with strong local capabilities."

Nozu Builds on Growing Portfolio in Kyushu and Beyond

The Nozu project extends Trina Storage's track record in Japan's utility-scale energy storage market. The company is additionally supplying a 160 MWh utility-scale BESS project in the Kyushu region, where Oita Prefecture is located.

In September, Trina Storage signed a memorandum of understanding with AMP-lify covering approximately 1GWh of grid-connected BESS projects in Japan, featuring the company's latest Elementa 3 series. According to the company, the MoU, together with projects like Nozu, reflects continued expansion in Japan as demand for utility-scale energy storage grows.
