Will Saft supply a battery energy storage system in Fukushima?

Tokyo, 12 June 2025 – Saft, a subsidiary of TotalEnergies, has been selected by leading Asian renewable energy developer Gurīn Energy to supply a battery energy storage system (BESS) for the latter’s major energy storage project being developed in Fukushima, Japan.

Why is battery storage important in Japan?

Once operational, the battery storage systems will help balance supply and demand on the national power grid. Battery storage is viewed as an important part of Japan’s decarbonization plans. Storage systems like BESS help keep power systems stable, especially when more electricity comes from solar and wind sources.

Why should Japan add energy storage capacity?

Adding energy storage capacity will allow Japan to ensure a stable and sustainable supply of energy and avoid curtailment of renewable energy.

What is Japan's storage battery industry strategy?

The “Storage Battery Industry Strategy” document from METI sets out three key targets: Boost Domestic Manufacturing: Japan aims to ramp up its domestic production of automotive storage batteries to 100 GWh by 2030, with a long-term goal of reaching 150 GWh annually. This move highlights the potential for foreign companies to invest in Japan.

How do storage systems work in Japan?

Storage systems like BESS help keep power systems stable, especially when more electricity comes from solar and wind sources. Other projects in Japan include a municipal BESS project in Iida City, Nagano Prefecture. This small-scale system, with an installed capacity of 2 MW/4 MWh, is operated by a city-owned energy company.
