FAQS about Japan promotes new energy storage

What is Japan's energy storage policy?

As policy, technology, and decarbonization goals converge, Japan is positioning energy storage as a critical link between its climate targets and energy reliability. Japan’s energy storage policy is anchored by the Ministry of Economy, Trade and Industry (METI), which outlined its ambitions in the 6th Strategic Energy Plan, adopted in 2021.

How is Japan's energy storage landscape changing?

Japan’s energy storage landscape is shifting, pushed by household demand, corporate ESG mandates, and domestic battery manufacturing. The residential lithium-ion market, projected to grow at a CAGR of 33.9% through 2030, remains one of the fastest-expanding segments.

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 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.

How much will Japan's energy storage system cost in 2023?

The $593 million worth of commercial energy storage systems recorded in Japan in 2023 could balloon to $4.15 billion by 2030, InfoLink reckons, with “industrial adoption expected to scale faster,” according to the data company.

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.
