Tokyo energy storage cabinet battery customization

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.

Several megawatt-hours of residential battery storage systems, typically paired with solar PV, are being installed in Japan on a monthly basis. This is largely due to concerns about losing power at home, given the seismic activity the country is frequently subject to, as well as extreme weather events like typhoons.

Another Tokyo-headquartered utility, Tokyo Gas, also began a similar programme with residential batteries. The company markets and installs battery storage systems to households, and also has a new solutions service, branded Igniture, which controls the charging and discharging to participate in power supply-demand balancing.

Each battery energy storage container unit is composed of 16 165.89 kWh battery cabinets, junction cabinets, power distribution cabinets, as well as battery management system (BMS), and the auxiliary systems of distribution, environmental control, fire protection, illumination, etc. inside the container; the battery container is 40 feet in size.

Tokyo Gas opened its Battery Control Service programme to customer enrolment on 26 August, offering an upfront fee of ¥10,000 (US$70) for joining and ¥200 per month thereafter.
