Technical FAQs 4

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 Tokyo Gas have a battery energy storage system?

Tokyo Gas is also participating in the Japanese utility-scale battery energy storage system (BESS) market, signing a 20-year tolling offtake deal with Australian developer Eku Energy for a forthcoming 30MW/120MWh project.

Will Japanese energy storage projects have a merchant component?

Future large-scale projects that have a merchant component are set to increase as sophisticated players from more mature power markets such as Australia, UK and US enter the Japanese energy storage market.

Where in Japan will a solar power plant be built?

Geographically, three of the projects will be built in Ibaraki Prefecture, two in Kanagawa, Chiba, and Tochigi each, and one in Tokyo, Saitama, and Gunma each. As Japan works to expand battery storage amid growing solar and wind capacity, METI also runs a similar subsidy scheme at the national level.
