Hirasol Energy Inc. (Headquarters: Bunkyo Ward, Tokyo; Representative Director: Min Li; hereinafter "the Company") is pleased to announce that its grid-scale storage facility "Tokushima Prefecture Yoshinogawa City Kamiura Grid-Scale Storage Facility" (hereinafter "this Storage Facility") in Kamiura, Yoshinogawa City, Tokushima Prefecture, was grid-connected and commenced operation on April 6, 2026.
This Storage Facility was built with design, construction, and equipment procurement handled by our wholly-owned subsidiary, Hirasol Densetsu Co., Ltd., with development support from Wire Energy Inc. and Energy Concierge Inc. Moving forward, the Company will operate as an aggregator using its market trading-enabled energy management system "J-EMS," contributing to grid stabilization and effective utilization of renewable energy by providing adjustment power to the supply-demand adjustment market.
## Background and Significance
With the large-scale introduction of renewable energy, power grids are becoming increasingly volatile, making the securing of "adjustment power" (Note 1) a more critical issue than ever. This Storage Facility is expected to promote further dissemination of renewable energy and maintain a stable power grid by providing adjustment power through the supply-demand adjustment market.

## Main Activities by the Company
### ■ Design and Construction of the Storage Facility
The design, construction, and equipment procurement for this Storage Facility were handled by our subsidiary, Hirasol Densetsu Co., Ltd. From the design stage to grid connection, we have built a stable operating system by taking safety and maintainability into account, providing flexible responses tailored to the site environment and installation conditions, and managing construction by our own engineers.
### ■ Introduction of Energy Management System "J-EMS"
We have introduced our proprietary energy management system "J-EMS" to optimally control the charging and discharging of the batteries.
"J-EMS" is a system that uses the cloud to predict demand and market prices with high accuracy, bids in multiple markets such as the wholesale electricity market and the supply-demand adjustment market, and then controls on-site equipment based on instructions from the market after winning bids.
It achieves optimal charging and discharging by collaborating with various devices through self-developed hardware (edge). Through these controls, it contributes to maximizing the profitability of storage facilities and power plants, stable utilization of renewable energy, and further CO₂ reduction.
## Future Development
Based on its proprietary energy management system "J-EMS," the Company is developing its business as an aggregator responsible for forecasting, control, and market bidding in various markets, including the supply-demand adjustment market. Moving forward, leveraging the strength of developing and operating EMS in-house as an aggregator, we will promote grid-scale battery projects nationwide and contribute to renewable energy...
