Launch of the MSB Kanagawa Aikawa Energy Storage Plant

On September 1, 2025, PowerX Inc., based in Tamano, Okayama, commenced the commercial operation of the MSB (Mirror Storage Battery) Kanagawa Aikawa Energy Storage Plant in Aikawa Town, Kanagawa Prefecture, in collaboration with MIRARTH Asset Management Co., Ltd., located in Chiyoda, Tokyo. This project marks a significant step in integrating cutting-edge energy storage technology into Japan's renewable energy efforts.

Innovative Energy Solutions

The MSB Kanagawa Aikawa Energy Storage Plant utilizes an advanced energy storage system, the Mega Power 2700A, developed by PowerX. This facility represents the first instance where this technology is deployed in a power aggregation service, showcasing a pioneering approach in the sector. The energy produced will be utilized not only for the company's retail electric operations, including its corporate renewable energy services (X-PPA) but will also participate actively in wholesale electricity markets, capacity markets, and demand adjustment markets.

Strategic Partnership for Stability

PowerX has entered into a leasing agreement with MIRARTH, implementing a fixed-price payment scheme known as 'Storage Factory Touring®', which ensures stable revenue for the MSB Plant. This arrangement will enable the energy storage facility to generate predictable cash flows, providing a solid financial foundation for future operations. As demand for renewable energy surges, both firms aim to enhance local grid stability while expanding their renewable capabilities.

Facility Specifications

The MSB Kanagawa Aikawa Energy Storage Plant is equipped with three Mega Power 2700A units, providing a total storage capacity of 7.4MWh and an output of 1.99MW. This facility will serve vital roles in balancing supply and demand throughout its operational lifespan.

Future Vision

PowerX and MIRARTH are committed to advancing the development of energy storage plants, reinforcing their joint aim to aid the expansion of renewable energy in the region. By addressing energy demands efficiently, they strive to make a meaningful contribution to regional grid stability during this critical phase of renewable energy growth.
