Risen recently secured a contract with two Japanese clients for 20 sets of its Risen eFlex 836kWh liquid cooling energy storage systems. As a new generation energy storage product launched by Risen in early 2025, this project collaboration marks a significant milestone. It not only represents the first deployment of Risen’s eFlex 836kWh liquid cooling energy storage systems in Japan but also demonstrates Risen’s major breakthrough in the Japanese energy storage market, leveraging its technological strength and product advantages.
Currently, Japan is vigorously advancing its energy transition with core goals of achieving 36%-38% renewable energy power generation by 2030 and carbon neutrality by 2050. The two projects are located under the jurisdiction of Tokyo Electric Power and Tohoku Electric Power, both of which are core areas with dense populations and industries. These regions experience high electricity loads and frequent fluctuations, placing stringent demands on the response speed, stability, and adaptability of energy storage systems. There is an urgent need for high-quality flexible regulation resources to support grid operations. Risen has precisely targeted this market demand by introducing customized solutions to enter the Japanese energy storage market.
The projects will operate as independent energy storage stations and participate in frequency regulation and other ancillary services in Japan’s electricity market. By supplementing frequency regulation resources and stabilizing regional grid frequency, the projects will enhance the power supply reliability in the Tokyo and Tohoku Electric Power regions, injecting new momentum into Japan’s energy structure transition.
