PowerX receives order for energy storage system for extra-high voltage power storage facility from Kurihara Kogyo

PowerX Inc. (Headquarters: Tamano City, Okayama Prefecture; Representative Director, President & CEO: Masahiro Ito; Securities Code: 485A) has received an order from Kurihara Kogyo Co., Ltd. (Headquarters: Kita-ku, Osaka City, Osaka Prefecture; Representative Director, President: Kazuhisa Shikatani) for 16 units of its "Mega Power 2500" energy storage system (total capacity: 40.1 MWh) for an extra-high voltage power storage facility to be newly constructed in Akō City, Hyogo Prefecture.

The "Akō Power Storage Facility," to be newly constructed, will connect to the Kansai area's power grid and contribute to stabilizing the power supply-demand balance by charging during periods of surplus electricity and discharging during periods of shortage. It is scheduled to start operation within 2028.

This project has been adopted for the "FY2025 Subsidy Project for Expanding Renewable Energy Introduction and Introducing Grid-Connected Storage Batteries and Other Power Storage Systems" supervised by the Ministry of Economy, Trade and Industry.

This is the third grid-connected power storage facility for Kurihara Kogyo to adopt our energy storage system, following the "Daigo Power Storage Facility" (Daigo-machi, Kuji-gun, Ibaraki Prefecture), which started operation in February 2026, and the "Awaji Island Power Storage Facility" (Awaji City, Hyogo Prefecture), which is currently under construction.

PowerX, a domestic manufacturer of energy storage systems, and Kurihara Kogyo, a comprehensive engineering company with extensive experience in the power infrastructure sector, will continue to contribute to the realization of carbon neutrality in Japan through the construction of power storage facilities.
