Japan had 1,671MW of capacity in 2022 and this is expected to rise to 10,074MW by 2030. Listed below are the five largest energy storage projects by capacity in Japan, according to GlobalData’s power database.

Why is battery storage important in Japan?

They store solar power for use at night and ensure a steady green energy supply, crucial for Japan’s sustainability goals and the Green Transformation (GX) initiative. In short, battery storage is now crucial due to the boom in solar power and the increasing demand for green energy from emerging industries.

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.

What is Japan's first energy storage project?

In 2015, we started Japan's first demonstration project covering energy storage connected to the power grid in the Koshikishima, Satsumasendai City, Kagoshima. This project is still operating in a stable manner today. One feature of our grid energy storage system is that it utilizes reused batteries from EVs.

Does Japan have a grid-scale battery market?

As Japan takes a leading role in Asia’s grid-scale energy storage market, it’s attracting international companies, including players like Tesla, which is known for its large-scale battery storage product, the Megapack. Japan NRG examines the latest trends in Japan’s grid-scale battery market.

Will Japan commercialize all-solid-state batteries by 2030?

In the 2024 Battery Industry Strategy, Japan set a target of commercializing all-solid-state batteries (ASSB) by around 2030. By the end of last year, the Ministry of Economy, Trade and Industry (METI) approved a total of four major R&D projects on ASSB materials and production, including that of Toyota, Idemitsu, Mitsui Kinzoku, and TK Works.
