Trina Storage Signs 1GWh Battery Energy Storage Memorandum of Understanding with Japan's AMP-lify

en.Wedoany.com Reported - On September 14, Trina Storage signed a memorandum of cooperation with Japanese clean energy developer AMP-lify, planning to supply approximately 1GWh of energy storage systems for grid-side battery storage projects developed by AMP-lify in Japan. Under the memorandum, Trina Storage will provide Elementa 3 series energy storage equipment, with its local Japanese team responsible for system configuration, technical consulting, delivery coordination, and after-sales service. This signing constitutes an equipment supply cooperation framework and is not a formal order that has locked in the full 1GWh of equipment procurement; the specific project scale, delivery batches, and contract amounts have not yet been disclosed.

This cooperation will primarily adopt the Elementa 3 series. The standard version of Elementa 3 is equipped with Trina Storage's self-developed 587Ah lithium iron phosphate cells, with a single 20-foot energy storage unit offering a maximum capacity of 6.25MWh, targeting large-scale grid-side energy storage projects. Compared with the previous generation, its module energy density has increased by approximately 12.3%, and its site-level energy density has increased by approximately 24.7%. The core design direction is to reduce the land footprint and per-unit energy storage cost of large-scale energy storage projects.

In response to Japan's road transport, site area, and surrounding community constraints, the cooperation projects may also adopt the Elementa 3 Flex. This model has a single-unit capacity of 1.56MWh, occupies approximately 5 square meters, weighs approximately 13 tons, can be transported by standard trucks, maintains operating noise below 65 decibels, and supports modular expansion. The product is also configured with IEEE 693 seismic design, C4/C5 corrosion protection ratings, and IP67 module protection for Japan's coastal, high-humidity, and seismic environments, covering energy storage sites in urban suburbs, mountainous areas, and locations with limited transportation conditions.

The division of responsibilities between the two parties in project execution has also been clarified. AMP-lify is responsible for project development, construction, and operation within Japan, while Trina Storage intervenes early in the project for equipment selection and system design and provides local technical support. Japanese energy storage sites typically need to simultaneously address road weight limits, narrow road transport, mountainous terrain, limited land, noise restrictions, seismic resistance, and coastal corrosion. Therefore, this cooperation is not a single batch delivery of standard equipment, but rather involves system configuration tailored to specific sites before proceeding to equipment supply and engineering delivery.

AMP-lify currently develops, constructs, and operates grid-side energy storage, large-scale photovoltaic, and onshore wind projects in Japan. Its public project portfolio shows that the company has approximately 556MW of renewable energy projects in operation or under construction in Japan, with another approximately 432MW under development, and has advanced a battery energy storage project of approximately 215MWh in Fukui Prefecture. This approximately 1GWh cooperation framework will become an important supply foundation for its subsequent energy storage project equipment procurement and standardized construction.

Trina Storage has previously established an actual delivery record in Japan. In 2025, the company completed delivery of approximately 16MWh of energy storage systems in Gunma Prefecture; in June 2026, it signed a 160MWh energy storage project in the Kyushu region, with equipment scheduled for delivery in 2026 and commercial operation in 2027. This expansion of cooperation with AMP-lify to approximately 1GWh means its Japanese business is advancing further from single hundred-megawatt-hour-level projects toward multi-project portfolio supply.
