HOBE ENERGY Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Kyoichi Okino; hereinafter "HOBE ENERGY") announces the successful completion of power reception on March 31, 2026, at the "Shichihongi Battery Storage Station," which was being developed in Kamisato-machi, Kodama-gun, Saitama Prefecture by Japan Energy Storage Development Initiative Inc. (Headquarters: Minato-ku, Tokyo; Representative Director: Akira Hoshino; hereinafter "JESDI"), a company engaged in the development and promotion of grid-scale battery energy storage systems (BESS).
This project represents a consecutive achievement following the Kamina Battery Storage Station (Kumagaya City, Saitama Prefecture; 5MWh), which completed power reception on March 27, 2026. This further solidifies HOBE ENERGY's track record in deploying its proprietary grid-scale energy storage systems and EMS (Energy Management Systems).
■ Expanding Role of Grid-Scale Batteries Essential for the Renewable Energy Era to Support Power Infrastructure
With the expanding adoption of renewable energy, managing output fluctuations caused by weather and time of day has become a critical challenge for Japan's power infrastructure. As the ratio of renewable energy increases, the development of grid-scale batteries capable of storing surplus power and discharging it when needed is essential to maintain power grid stability. Furthermore, energy security is a vital national issue for Japan, requiring a shift away from an energy structure highly dependent on foreign sources, the establishment of decentralized energy foundations, and the strengthening of power supply resilience.
Amidst this, the government is enhancing support for the deep-tech sector, further raising expectations for battery storage and energy management technologies. Grid-scale batteries are drawing attention as a foundational technology for next-generation power infrastructure, providing the adjustment capability that supports the widespread use of renewable energy. Against the backdrop of these societal demands, HOBE ENERGY has built a comprehensive structure to seamlessly offer design, procurement, implementation, and operational support for battery systems, contributing to the development of social infrastructure in the renewable energy era.
■ Significance for HOBE ENERGY: Accelerating the Deployment of Grid-Scale Energy Storage Systems
Having established the first successful deployment of its proprietary grid-scale energy storage system at the Kamina Battery Storage Station, HOBE ENERGY swiftly demonstrated its reproducibility by achieving power reception at the Shichihongi Battery Storage Station on the 31st of the same month. Achieving the process from commencement to power reception right on schedule across multiple consecutive projects demonstrates the robustness of the company's end-to-end system encompassing design, procurement, EMS implementation, and construction coordination. Led by President and CEO Kyoichi Okino, an engineer with experience at Fuji Electric and ABB, HOBE ENERGY bases its management pillars on the development and utilization of domestic technology and contributing to energy security. This project steadily advances that strategy.
