Japan Energy Storage Development Initiative (JESDI; Head Office: Tokyo; Representative Director: Akira Hoshino), which promotes the social implementation of grid-scale battery energy storage systems (BESS), completed power reception on March 31, 2026, at the 'Shichihongi Energy Storage Plant' that had been under development in Kamisato-machi, Kodama-gun, Saitama Prefecture.
■ Installation Overview and Technical Features
This energy storage plant secures a capacity of 5MWh against an output of 2MW and plays the role of 'primary reserve' to maintain the frequency of the power grid.
While industry-standard 20ft containers dominate, this plant adopts a 5ft compact energy storage system manufactured by HOBE ENERGY. This is an implementation model tailored for site constraints, enabling installation even in locations with narrow access routes or sharp curves, vastly increasing the flexibility of selecting candidate sites. Furthermore, it achieved power reception in a short period of about three and a half months from the start of construction, advancing the standardization of design and construction processes to shorten the lead time for market entry.

FAQ
What are the features of the Nanakita Energy Storage Facility?
Instead of standard large containers, HOBE ENERGY's 5ft compact energy storage system is used, enabling installation in small spaces and reducing construction time.
What role does it play?
It has an output of 2MW and a capacity of 5MWh, functioning as 'primary frequency regulation' to maintain the power system's frequency.
How fast is the development process?
Through standardization of the design and construction process, the facility achieves operation (commissioning) in approximately 3.5 months from the start of construction.
