What are Japan's new battery energy storage regulations?

The government is also reforming its battery energy storage system (BESS) regulations, with batteries set to play an important role in maximizing renewable energy supply and avoiding grid constraints. We look at the changes being implemented and what they mean for renewable energy projects in Japan.

Why are Japanese companies investing in battery energy storage systems?

Sign up here. That is creating surging interest in battery energy storage systems (BESS) to smooth mismatches in supply and demand. Since December 2023, companies have announced investments of at least $2.6 billion in Japanese battery storage projects, according to calculations by Reuters.

How much battery power does Japan have?

As of March, Japan had 0.23 GW of grid-connected BESS, according to METI. By comparison, China has 75 GW and the U.S. has installed nearly 26 GW of battery storage capacity, according to the Energy Institute.

Does Japan have a solar power plant?

t new-build renewable power plants in Japan include an energy storage component. The two largest solar PV power plants in Hokkaido, commis oned in July and October 2020, respectively, both include lithium ion batteries. One plant has generating capacity of 64.6MWp and battery output of 19.0MWh,

Should battery storage be installed in Japan?

Installing battery storage would reduce the cost of upgrading the grid and avoid wasting clean generation. Most BESSs in Japan are currently co-located with renewable power installations, but the country is increasingly looking at installing standalone systems to provide grid balancing services.

How big is Japan's battery storage market?

In the commercial space, Japan’s battery storage market was valued at USD 593.2 million in 2023 and is projected to reach USD 4.15 billion by 2030. While commercial installations currently dominate revenues, industrial adoption is expected to scale faster. Utility-scale storage is also gaining ground.
