HOBE ENERGY Sets New Standard with the Launch of 5MWh Storage Facility

On June 16, 2026, HOBE ENERGY Co., Ltd., based in Tokyo, Japan, proudly inaugurated its latest 5MWh-scale energy storage project, named the Nanamiki Storage facility, located in Kamisato Town, Saitama Prefecture. This significant step comes just 2.5 months after the completion of transmission, marking HOBE ENERGY's solid entry into the demand-supply adjustment market alongside another facility, the Uenara Storage, which also commenced operations on the same day.

This project was announced via a press release on March 31, 2026, highlighting the completion of its transmission capabilities. The rapid launch showcases HOBE ENERGY's efficient model of combined equipment design and supply, along with their proprietary Energy Management System (EMS). The facility's swift transition from planning to market readiness signifies the high reproducibility of HOBE ENERGY's systems.

Value of Proprietary EMS and One-Stop Solutions

The standout feature of the Nanamiki Storage facility is the advanced EMS developed in-house by HOBE ENERGY. Unlike traditional systems that only provide basic charge-discharge controls, this EMS employs sophisticated control technologies that can rapidly respond to stringent demand-supply adjustment market requirements. By closely integrating the facility's design with RUTILEA's power trading optimization AI, the team has significantly compressed the time required for connection adjustments and system integration testing.

Rather than simply providing a product, HOBE ENERGY's engineers have provided thorough support to customers through advanced technical discussions with organizations like the OCCTO (Organization for Cross-regional Coordination of Transmission Operators) and TSO (Transmission System Operator). This in-depth involvement has enabled the expedited launch of the facility.

Future Prospects: Mass Production of Grid Storage Systems

The concurrent operation of the Uenara and Nanamiki facilities indicates that HOBE ENERGY has successfully established a model for mass production of grid storage stations. Moving beyond the initial success of a single project, HOBE ENERGY has proven its ability to launch multiple projects simultaneously, ready for market entry within a short timeframe of just 2.5 months regardless of varying schedules and site conditions.

As Japan aims to achieve a renewable energy ratio of 40-50% by the fiscal year 2040, the urgent need for rapid and large-scale social implementation of grid storage systems is paramount to enhancing national energy security. HOBE ENERGY aims to leverage this robust collaborative model within four company partnerships to ensure smooth system supply for upcoming projects spearheaded by JESDI, including facilities in Hachigata and Orinokuchi, thereby responding comprehensively to national demands for grid stabilization across multiple locations.

CEO's Comment on the Successful Launch

CEO Koichi Okino commented, "We are incredibly proud to see both the Uenara and Nanamiki storage facilities operational in such a short span of just 2.5 months following the completion of transmission. My sincere gratitude goes to JESDI’s President Akira Hoshino, the construction partner E-top, and operational support from RUTILEA.
Our strength lies not only in providing equipment but also in offering our customers comprehensive support through specialized knowledge and our proprietary EMS. The current achievement underscores the effectiveness of our seamless process in solving customer challenges for swift market entry. We remain committed to contributing to Japan's energy autonomy and a decarbonized society."
