Technical FAQs 4

Is Japan a good place to invest in solar energy?

Japan's position in the global market is significant, as it is one of the largest solar energy markets, providing a gateway for companies looking to expand their renewable energy portfolios in Asia.

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.

Does Japan have a solar power industry?

Japan's solar power industry presents several key considerations for potential investors and stakeholders. The country has set ambitious renewable energy targets, aiming to increase its solar energy capacity significantly as part of its commitment to reduce greenhouse gas emissions.

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.
