Tokyo, June 12, 2025 – Gurīn Energy has appointed Saft, a subsidiary of TotalEnergies, as the supplier for its flagship 1-gigawatt-hour (GWh) energy storage project in Fukushima, Japan. The project is a milestone in Japan’s renewable energy transition and will significantly support the integration of clean power into the national grid.
Major boost for Japan’s renewable energy strategy
The Gurīn Energy energy storage project in Fukushima will be located in Soma City and is designed to deliver 240 megawatts (MW) of power for four hours. Construction is scheduled to begin in 2026. Saft’s lithium-ion BESS will play a vital role in storing excess electricity and releasing it when demand rises, thereby helping to balance the supply-demand equation in real time.
“This project is a major step for Japan’s energy transition,” said Vincent Le Quintrec, Sales and Marketing Director, Saft. “Our proven expertise in battery systems, coupled with Gurīn Energy’s strong renewable development capabilities, will help accelerate Japan’s climate ambitions.”

Smart battery systems and AI-powered management
The system will include Saft’s fully integrated lithium-ion battery technology, power conversion systems, and its advanced I-Sight cloud platform, which uses AI for predictive performance monitoring and energy optimization. Saft will also manage installation, commissioning, and maintenance, offering a complete energy storage solution.
According to Gurīn Energy’s Japan Country Manager Ushio Okuyama, “Our energy storage project in Fukushima will enhance flexibility across Japan’s power grid. We are proud to partner with Saft and confident in our shared mission to accelerate Asia’s clean energy transition.”
Strategic support for national energy goals
The large-scale battery installation supports Japan’s goal of achieving 40–50% renewable energy in its generation mix by 2040 and carbon neutrality by 2050. With renewable energy currently accounting for 27% of national power, projects like Gurīn Energy’s energy storage project in Fukushima are essential for sustainable growth.
