Trina Storage, a global leader in integrated battery energy storage system (BESS) solutions, has successfully commissioned its advanced Elementa 2 BESS at two utility-scale power plants in Japan’s Gunma Prefecture. This dual-site deployment marks a significant milestone in Trina Storage’s expanding footprint across the Asia-Pacific region, where it currently has over 2.4 GWh of BESS capacity under execution.
Delivered and brought online in under three weeks, the Elementa 2 systems were deployed simultaneously at two separate locations—demonstrating Trina Storage’s agile and efficient delivery model. The execution combined the expertise of Trina’s global engineering team with the on-ground knowledge of local technical specialists.
The two projects collectively deliver 16 MWh of storage capacity—enough to power approximately 1,500 households—and support a variety of applications including energy arbitrage, frequency regulation, and capacity firming. The systems are fully compliant with Japan’s strict high-voltage grid standards.
The Elementa 2 platform has received multiple global safety and performance certifications, including the world’s first UL certification for liquid-cooled thermal control, TÜV NFPA69 explosion-proof ventilation certification, IEC 61508 Functional Safety Process Certificate, and Japan’s JET fire propagation test—the first awarded to a non-domestic brand.
Trina Storage was praised by the client for its speed, professionalism, and robust local support. As a BloombergNEF Tier 1 energy storage manufacturer for six consecutive quarters, Trina continues to demonstrate strong bankability and system reliability.
“Completing two grid-connected projects in just three weeks reflects our end-to-end capability—from manufacturing to commissioning—with a strong understanding of Japan’s regulatory framework,” said Li Na, General Manager of Trinasolar Japan. “We are grateful for our client’s trust and are committed to accelerating energy transition efforts across APAC.”
This successful deployment positions Trina Storage as a key player in Japan’s energy market and further strengthens its role in the region’s clean energy transition.
