Joshin Denki Co., Ltd. announced that it teamed up with JA Mitsui Energy Solutions, Ltd. and i GRID SOLUTIONS Inc. and installed a solar power generation facility "GX Store" 1 with a large-capacity rechargeable battery system at Joshin Matsudo Store. The Group has been proactively implementing in-house power generation and consumption of renewable energy through photovoltaic systems at each of business sites. This system enables Joshin Matsudo Store to cover about 40% of the total electricity used for daytime operations with electricity generated by the photovoltaic system.

Furthermore, by installing a large-capacity rechargeable battery system, the power generated during periods and times of high power generation will be stored in the battery system and discharged during periods of high power usage and in the evening, thereby increasing the self-sufficiency rate of renewable energy. In addition, it will serve as an emergency power source not only in normal conditions but also in times of emergency (power outage), enabling business continuity and disaster resilience, and will also play a role as a regional disaster prevention base.
