Recently, Risen Energy successfully shipped 80 sets of liquid-cooled energy storage containers to the United States. This batch of energy storage systems will serve Middle River Power’s 40MW/401.28MWh power station. The power station will not only bring Middle River Power long-term and stable returns but also fully demonstrate Risen Energy’s outstanding technological innovation capability and strong delivery capacity, further expanding its influence in the North American market.
This project is located in California. As a leader in the U.S. new energy market, the California market has strict requirements for indicators such as energy storage system safety, energy efficiency, and land use. For the project, Risen Energy provided the eTron 5MWh liquid-cooled energy storage system, adopting a 0.25C storage design and a single-unit liquid cooling air-conditioning design, using the latest R513a clean refrigerant, which meets the U.S. Environmental Protection Agency’s requirements for low Global Warming Potential (GWP). Facing California’s extreme temperature environment of –30°C to 50°C, the eTron liquid-cooled energy storage system solution performed excellently, successfully solving common thermal management and uniformity issues in high-power applications and ensuring the continuous and stable operation of energy storage equipment; achieving coordinated operation of BMS, PCS, and Golden Shield system, with a five-level protection system from cell to system to ensure safety. In addition, innovative designs such as single-direction opening doors, mirror design, and square layout further save land use and enhance overall project efficiency. The application of these innovative technologies makes Risen Energy’s products stand out among similar products.
Risen Energy has extensive experience in the energy storage market, with projects across China, Australia, Europe, the United States, and the Asia-Pacific region, and has successfully implemented more than 400 energy storage projects. The successful delivery of this 402MWh California energy storage project is yet another strong proof of its powerful capabilities.
In 2025, Risen Energy officially entered the inverter sector and launched three integrated solar-plus-storage solutions for different scenarios—Shengjia, Shengqi, and Shengneng—precisely meeting the diversified needs of residential, C&I, and large-scale ground-mounted power plants, further expanding its competitiveness and influence in the global energy market. In the future, Risen Energy will actively expand into the global market, help drive the global energy transition, and contribute more to achieving sustainable development goals.
