RE100 Electric Power Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President & CEO: Katsuhiro Konishi; hereinafter “RE100 Electric Power”) announces the conclusion of a business alliance agreement with Wave Energy Co., Ltd. (Headquarters: Minato-ku, Tokyo; President & CEO: Yasuhiro Hano; hereinafter “Wave Energy”) aimed at maximizing the revenue of renewable energy power plants and enabling advanced operations in the electricity market.

Background of the Business Alliance
With the expansion of renewable energy adoption, the installation of power generation facilities, primarily solar power, has been progressing nationwide. However, as renewable energy is inherently subject to output fluctuations due to weather conditions, addressing generation variability, managing grid constraints, and improving the profitability of power producers have become critical challenges. In particular, as mega-solar power plants transition from the FIT (Feed-in Tariff) scheme to the FIP (Feed-in Premium) scheme, there is a growing demand for generation operations based on market prices and advanced utilization of the electricity market, driving increased need for operational optimization through grid-scale battery storage.
RE100 Electric Power, as an aggregator that comprehensively manages electricity supply and demand, provides advanced power operation services utilizing the electricity market and the supply-demand adjustment market. Meanwhile, Wave Energy possesses strengths in battery storage-related technologies and power equipment solutions, providing hardware solutions that support the advancement of renewable energy facilities.
Leveraging their respective strengths, the two companies have entered into this business alliance with the objective of jointly deploying a solution for the retrofit installation of grid-scale battery storage at existing mega-solar power plants.
Details of the Business Alliance
Through this alliance, the companies will propose the installation of grid-scale battery storage to mega-solar operators and provide a solution aimed at maximizing revenue by targeting 24-hour operation of generation facilities. This will be achieved by actively leveraging the FIP scheme and the supply-demand adjustment market (primary balancing capacity), pursuing innovative approaches to energy market participation.
Future Outlook
Through this alliance, both companies will promote the installation of battery storage at existing mega-solar power plants, supporting the advancement and improved profitability of renewable energy power plant operations.
Furthermore, the companies will work to expand electricity market operations utilizing battery storage, contributing to the stable supply of renewable energy and the advancement of power systems.
