Trina Storage, the energy storage business unit of Trinasolar, has secured a major supply contract for the AEJ Nozu Battery Energy Storage System (BESS) project in Japan. The project represents a significant step forward in the country's utility-scale energy storage sector, highlighting the growing demand for grid-scale battery solutions to support renewable energy integration.

Located in Nishihata, Nozu Town, Usuki City, within the Oita Prefecture, the AEJ Nozu project is designed with a capacity of 50MW / 196MWh. Under the terms of the agreement, Trina Storage will supply its advanced Elementa 2 Pro 5MWh battery energy storage solution. The project was awarded under Japan's FY2023 Long-Term Decarbonization Auction, with completion scheduled for the third quarter of 2028.

Supporting Japan's Decarbonization Strategy

The AEJ Nozu project is positioned within Japan's broader efforts to transition toward clean energy sources. By securing a position under the FY2023 Long-Term Decarbonization Auction, the project aligns with national initiatives aimed at stabilizing the electrical grid as renewable energy deployment expands.

Grid-scale battery storage systems like the AEJ Nozu BESS are critical for managing the intermittency associated with solar and wind power. By storing excess energy during periods of high generation and releasing it during peak demand, these systems help maintain grid stability and reduce reliance on fossil-fuel-based power plants.

Technology Deployment: Elementa 2 Pro

For the AEJ Nozu project, Trina Storage will deploy its Elementa 2 Pro 5MWh battery energy storage solution. This system is designed to meet the rigorous safety, efficiency, and reliability standards required for utility-scale applications.

Trina Storage's technology portfolio is built on global experience in:

  • Battery cell technology development
  • Comprehensive system integration
  • Utility-scale energy storage deployment

This technical foundation allows the company to deliver systems that optimize energy density and operational lifetime, addressing the specific technical requirements of the Japanese market.

Expanding Footprint in the Japanese Market

The AEJ Nozu project adds to Trina Storage's expanding track record in Japan's competitive utility-scale energy storage sector. The company has been actively building its portfolio through multiple high-profile initiatives across the country:

  • Supply of a 160MWh utility-scale BESS project in the Kyushu region.
  • Signing of a Memorandum of Understanding (MoU) in September with AMP-lify for approximately 1GWh of grid-connected BESS projects in Japan, which will feature the latest Elementa 3 series.

These projects demonstrate a sustained expansion strategy, positioning Trina Storage as a key technology provider as Japan's demand for utility-scale energy storage continues to rise.

Local Capabilities and Lifecycle Support

To support its growing project pipeline, Trina Storage has established dedicated local capabilities in Japan. The local team works closely with customers and project partners to navigate regional technical standards and project requirements.

The company's localized support structure covers the entire project lifecycle, including:

  • System configuration and engineering design
  • Technical consultation tailored to local grid codes
  • Delivery coordination and logistics management
  • Comprehensive after-sales service and maintenance

This combination of global manufacturing and technology expertise with strong local execution capabilities is central to Trina Storage's approach to the Japanese market.

Executive Insights

Dr. Leo Zhao, Head of Energy Storage (APAC) at Trina Storage, emphasized the strategic importance of the project and the company's commitment to the region.

"We are pleased to support Japan's growing renewable energy portfolio through the AEJ Nozu Battery Energy Storage System project,“ Zhao stated. ”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."

As the third quarter of 2028 approaches, the successful delivery of the AEJ Nozu project will serve as a key milestone for Trina Storage, further cementing its role in East Asia's energy transition.
