HOBE ENERGY's Newest Milestone: The Hatchi Battery Storage Site

On July 13, 2026, HOBE ENERGY, a leading player in next-generation battery solutions, celebrated the successful energization of its Hatchi Battery Storage site located in Yoshikata, Saitama Prefecture. This project, managed by Japan Energy Storage Development Institute (JESDI), marks the third battery storage facility to begin operations in Saitama, following the recent launches at Uenara and Nanbongi.

Rapid Implementation: Four Months to Energization

Demonstrating their efficiency, HOBE ENERGY managed to complete the energization of Hatchi Battery Storage in just four months post-construction start, having begun on March 24, 2026. This remarkable achievement showcases the company's commitment to rapid project implementation, employing their standardized, mass-production approach to solutions.

The Hatchi project boasts a capacity of 5MWh and an output of 2MW, featuring HOBE ENERGY's integrated battery system, combining Battery Management Systems (EMS), Power Conversion Systems (PCS), and transformer equipment. By streamlining the entire supply chain, HOBE ENERGY conducted operations with optimized efficacy, ensuring delivery times that meet the dynamic energy market's needs.

Tackling Challenges with Innovative Solutions

Recognizing the pressing issue of abandoned farmland due to aging agricultural workers, HOBE ENERGY has positioned itself as more than just a battery vendor. The Hatchi facility is part of a larger initiative to repurpose underutilized land, or 'idle farmland,' into functional energy infrastructure. With the complexities involved in accessing many of these sites, HOBE ENERGY introduced a compact 5ft container design to navigate narrow access routes and sharp turns that standard 20ft containers cannot. This innovation effectively revitalizes previously inaccessible areas for energy storage, supporting local communities and addressing energy retention challenges.

A Collaborative Approach for Future Endeavors

HOBE ENERGY is not alone in its efforts. Together with JESDI, construction partner E-Top Co., Ltd., and operational support from RUTILEA Co., Ltd., a seamless collaboration enables a structured approach to energy innovation. With a strong four-company partnership, HOBE ENERGY can ensure quick adaptability to the demands of municipal governments and businesses grappling with land utilization and renewable energy integration issues.

As HOBE ENERGY moves forward after the successful commissioning of the Hatchi facility, the focus remains on maintaining relationship liquidity with JESDI while promoting the usage of renewable energy across Japan. They aspire to provide viable solutions that address community needs while fostering the evolution of an advanced energy infrastructure.

Quotations from the Leadership

Kyoichi Okinoya, President of HOBE ENERGY, expressed gratitude towards JESDI’s leadership under Hoshino Akira, and highlighted the exceptional execution from E-Top that managed the complex logistics of project implementation. He stated, "Achieving energization in four months at the Hatchi facility signifies our dedication to addressing complex challenges with innovative solutions. This project reaffirms our mission as a partner to our customers and the community."

As the company builds on its momentum from previous projects at Uenara and Nanbongi, HOBE ENERGY continues to enhance the standardization and reproducibility of its one-stop solutions to meet diverse needs and contribute to Japan's energy independence.
