Two Regional Microgrid Projects Utilizing PowerX's Battery Storage Systems Begin Operation
PowerX announced that two regional microgrid projects in Kinugasa Town, Iwate Prefecture, and Shizuoka City, Shizuoka Prefecture, which adopted its battery storage systems, have started operation this spring. These advanced initiatives combine solar power generation with battery storage to achieve both renewable energy utilization during normal times and independent power supply during disasters. Both projects have been selected for national subsidies, contributing to Japan's energy self-sufficiency and regional resilience.

Each project is an advanced initiative that combines solar power generation with battery storage systems, achieving both the utilization of renewable energy during normal times and an independent power supply during disasters. Furthermore, both projects have been selected for the Ministry of Economy, Trade and Industry's "Subsidy Program for Distributed Energy Resource Introduction Expansion towards Renewable Energy Introduction Expansion (Support Project for the Construction of Regional Independent Grids with a view to Entry into Electricity Distribution Business, etc.)."
PowerX, leading domestic manufacturing of battery storage systems, will continue to contribute to improving Japan's energy self-sufficiency and strengthening regional resilience through the provision of products to distributed energy businesses, including microgrids.
The outlines of each project are as follows:
■ 1. Kinugasa Resilience Grid (Kinugasa Town, Iwate Prefecture)
This is a regional microgrid introduced within Toyota Motor East Japan's Iwate Plant, which aims to utilize renewable energy within the factory during normal times. In the event of a disaster, by combining it with existing gas engine power generation facilities, it will be possible to supply power for more than 3 days to disaster prevention bases, evacuation shelters, and school lunch centers outside the factory premises.
Operators: Toyota Motor East Japan Corporation, Kinugasa Town
Adopted Product: Large-scale battery storage system "Mega Power 2700A" 1 unit (Storage capacity: 2,742 kWh)
Subsidy Project: FY2024 and FY2025 "Subsidy Program for Distributed Energy Resource Introduction Expansion towards Renewable Energy Introduction Expansion (Support Project for the Construction of Regional Independent Grids with a view to Entry into Electricity Distribution Business, etc.)."
Operation Start: April 1, 2026
■ 2. Hinode Regional Energy Supply Project (Shizuoka City, Shizuoka Prefecture)
This is a community-integrated energy supply model promoted by Suzuyo Shoji in the Shimizu Port Hinode area. Solar power generation facilities are introduced on the roofs of logistics facilities within the area, and combined with battery storage systems and EMS, they achieve local production and consumption of renewable energy. In the event of long-term power outages due to typhoons, etc., it will provide independent power supply within the area as a regional microgrid.
Operator: Suzuyo Shoji Co., Ltd.
Adopted Product: Large-scale battery storage system "Mega Power 2700A" 2 units (Total storage capacity: 5,484 kWh)
Subsidy Project: FY2024 "Subsidy Program for Distributed Energy Resource Introduction Expansion towards Renewable Energy Introduction Expansion (Support Project for the Construction of Regional Independent Grids with a view to Entry into Electricity Distribution Business, etc.)", FY2025 "Subsidy Program for Distributed Energy Resource Introduction Expansion / Distributed Energy Resource Introduction Support Project, etc. (Support Project for the Construction of Regional Independent Grids with a view to Entry into Electricity Distribution Business, etc.)."
Operation Start: March 24, 2026
