RENOVA, Inc. (Chuo-ku, Tokyo, Representative Director, President & CEO: Yosuke Kiminami; hereinafter "the Company") announces that it has today concluded a loan agreement for project financing of approximately 6.0 billion yen as business funds for the "Kikugawa Nishimura Battery Storage Power Station" (estimated output 90MW, estimated capacity 270MWh), which is being developed in Kikugawa City, Shizuoka Prefecture through an affiliated company, R1 Battery Storage LLC.
With the expected increase in electricity demand in the future, backed by the new establishment and expansion of data centers accompanying the recent spread of AI, securing stable power sources that do not emit CO2 is an urgent issue. This project is an advanced case of realizing large-scale project financing as a "market-sales type"*1 battery storage business that contributes to the stabilization of the power grid through participation in the supply and demand adjustment market, etc., without relying on subsidies or the Feed-in Tariff (FIT) system.
In 2023, the Company realized project financing for the Himeji Battery Storage Power Station (estimated output 15MW, estimated capacity 48MWh), which was the first of its kind in Japan for a market-sales type battery storage business. Leveraging the financing structuring capabilities cultivated at that time, we have now achieved financing structuring for this project, which is the largest scale in Japan.
*1 Market-sales type: A business model that secures revenue by providing "balancing capacity" and "supply capacity" in markets such as the "Supply and Demand Adjustment Market" and the "Capacity Market," without relying on government price guarantees (FIT system, etc.) or long-term fixed-price contracts with specific parties.
■ Four Features of this Project
1. Infrastructure Construction of the Largest Scale in Japan as a Market-Sales Type (90MW/270MWh)
This project boasts Japan's largest scale of 90MW/270MWh as a "market-sales type" battery storage power station that flexibly accesses multiple markets, such as the supply and demand adjustment market and the capacity market, without being bound by specific contracts. By providing large-scale balancing capacity, it will play a role as a core "energy infrastructure" supporting the next-generation power grid.
2. Achieving High "Cost Competitiveness" through Large-Scaling and In-Housing
This project utilizes the scale merit of being the largest in Japan to reduce project costs per MW. Furthermore, by in-housing the operation of the battery storage power station and utilizing the optimal operation knowledge cultivated internally, we pursue not only the suppression of operation costs but also the maximization of revenue through flexible operation according to the market environment. Anticipating intensified competition between battery storage power stations in the future, we have built a solid business foundation that possesses both sustainable revenue securing and competitive advantage.
3. High Reliability Based on the Track Record of Battery Storage Project Financing
This project has structured an advanced financing scheme as a large-scale battery storage project in Japan. This is proof that SBI Shinsei Bank, Limited has highly evaluated the stability and future potential of the business for the market-linked advanced operation model, and it demonstrates our strong fund procurement capabilities.
4. Contribution to Effective Utilization of Renewable Energy and Stabilization of Power Supply
By suppressing the output control of renewable energy and providing "balancing capacity" to utilize power without waste, we contribute to eliminating the tightness of power supply and demand. In addition, by actively participating in the "Supply and Demand Adjustment Market," which keeps power quality constant, and the "Capacity Market," which secures future supply capacity, we will fulfill our responsibilities as an infrastructure operator to reduce power costs and provide a stable supply for society as a whole.
With this investment decision, our battery storage business (including those in operation and under construction) has reached 352MW. This is a major step forward, corresponding to approximately 40% of the target of "900MW cumulatively by 2030" set forth in our mid-term business plan. Under the mission of "Creating green and independent energy systems," RENOVA will continue to further accelerate investments and contribute to the realization of a sustainable society by building the foundation for next-generation energy infrastructure.
