Trina Storage, the energy storage division of Trinasolar, said it has signed a memorandum of understanding with Japanese clean-energy developer AMP-lify to supply approximately 1 GWh of grid-connected battery energy storage system (BESS) equipment for AMP-lify’s projects in Japan.
Under the terms of the MoU, Trina Storage will supply its Elementa 3 BESS product line and provide technical support, system configuration, delivery coordination and after-sales service for the projects. The companies did not disclose the specific projects, locations, capacity split, or delivery schedule covered by the agreement.
AMP-lify was established in 2016 as a wholly owned Japanese subsidiary of Canadian developer Amp Energy. It was relaunched under its current name in 2025 following a 2024 investment from an Aravest/SMBC-backed infrastructure fund and Banpu NEXT, which it identifies as its leading shareholders.
Tokyo-based AMP-lify develops, builds and operates solar, onshore wind and grid-connected BESS projects in Japan. Its website lists 234 MW of BESS under development, along with 311 MW of solar and 222 MW of onshore wind in the development pipeline, and 280 MW of solar assets in operation or under construction.
Trina Storage‘s Elementa 3 uses the company’s in-house 587 Ah high-capacity cell and offers up to 6.25 MWh of energy capacity per container, according to Trina. The company also markets a smaller variant, the Elementa 3 Flex, with about 1.56 MWh of capacity, a roughly five-square-meter footprint, a weight of about 13 tonnes suited to standard-truck transport, and operating noise below 65 decibels.
Martin Stein, representative director and CEO of AMP-lify, said working with Trina Storage’s technology and local support gives the company a strong basis to move projects from site evaluation through construction and into operation.
Dr. Leo Zhao, head of energy storage at Trinasolar Asia Pacific, noted that Japan’s storage market has distinct engineering and delivery requirements, including road weight limits, narrow site access, mountainous terrain, seismic design considerations and community noise expectations, which the companies aim to address from the early stages of project development.
Japan’s Seventh Strategic Energy Plan, finalized in February 2025, targets renewables at approximately 40% to 50% of the country’s electricity mix by fiscal year 2040, up from 22.9% in fiscal 2023, with storage batteries and demand response identified as key tools for managing the variability of renewable generation.
Trina Storage signed a 160 MWh battery storage contract for a project in Kyushu in June 2026, using its Elementa 2 system, and has been active in Japan’s energy storage market since at least 2023.
