Launch of 'Disaster-Prevention Low-Voltage Power Storage Station' Business Compliant with the FY2026 Supply-Demand Adjustment Market

Mediotec Corporation (Headquarters: Shinjuku-ku, Tokyo, Representative Director: Hidemori Matsumoto, hereinafter "the Company") has reached a basic agreement on a business alliance with Esco Corporation (Headquarters: Okayama City, Okayama, Representative Director: Hidenori Kitayama), who will co-manage business planning, sales, and construction, and Girasol Energy Inc. (Headquarters: Bunkyo-ku, Tokyo, Representative Director: Min Li), who will handle the development and aggregation of EMS (Energy Management System), forming a partnership among the three companies. Through this alliance, the Company will further promote the construction of a Virtual Power Plant (VPP) that bundles distributed energy resources such as solar power generation and storage batteries, and will fully launch a low-voltage grid storage battery business compliant with the supply and demand adjustment market from FY2026. ■ Background and Initiatives for Starting the Business In Japan, securing the adjustment capability of the power supply and demand balance has become an important social issue along with the expansion of the introduction of renewable energy. In particular, the role of storage batteries as a flexible adjustment capacity to respond to the output fluctuations of renewable energy is rapidly increasing, and the state of power infrastructure is undergoing a major shift from "centralized" to "decentralized." Under these circumstances, the system reform allowing low-voltage (under 50kW) resources to participate in the supply and demand adjustment market from FY2026 signifies the creation of a new growth area in the energy sector. The Company has thus far accumulated a track record of introducing distributed power sources on a national scale through the development and sales of low-voltage solar power generation. In this business, by utilizing that knowledge and customer base, we will establish a new business model that accelerates the social implementation of distributed energy by integrally realizing: - Development and supply of low-voltage storage batteries - Integrated control (EMS) of distributed resources - Market utilization through aggregation This initiative creates new value for small-scale land that was previously difficult to utilize and contributes to the formation of a regionally distributed energy infrastructure, marking an important step toward realizing the VPP concept championed by the Company. ■ Features of the Business This business aims to create an unprecedented distributed energy investment market by standardizing 49.9kW/100kWh PCS-integrated storage batteries, enabling installation on small-scale land. The features of this business are as follows: 1. Contribution to Disaster Prevention and Regional Resilience During normal times, this power storage station generates revenue by participating in the supply and demand adjustment market, while during large-scale power outages, it supplies power to the local area as an emergency power source attached to the storage battery. Through distributed installation on small-scale land, it aims to form a resilient regional power network that does not depend on specific facilities. 2. Profit Model Utilizing System Reforms With the lifting of the ban on low-voltage participation in the supply and demand adjustment market from FY2026, the Company aims to enter the market early. It will integrally achieve integrated control by J-EMS (EMS/Aggregation System) and continuous revenue securing through aggregation. 3. Investment Scheme Accessible to Individuals and SMEs With a standard investment scale of approximately 20 million yen (excluding tax) per project, energy infrastructure investment, which was previously limited to large-scale facilities, will be opened up to individual investors and small and medium-sized enterprises. It can also be utilized as a new option for land utilization. ■ Roles and Strengths of the 3 Companies Mediotec Corporation: Business planning and general sales control. Utilizing nationwide low-voltage solar development track records and customer base. Esco Corporation: Construction and on-site response. Reliable construction quality and rapid deployment capabilities. Girasol Energy Inc.: Provision of J-EMS (EMS/Aggregation System). Maximizing market revenue with advanced control technology. ■ Future Outlook Through this business, utilizing the customer base and development know-how cultivated in low-voltage solar power generation as a foundation, the Company will strive to evolve into a "business model that integrates the development, sales, and operation of distributed energy assets." In the future, through the expanded introduction of low-voltage storage batteries and integrated operation by aggregation, we aim to construct an energy platform that bundles energy assets distributed throughout Japan.<
