AboutThe Yuanhe Energy team has been deeply engaged in the fields of energy storage systems, power electronics, and automatic control for many years, boasting over a decade of experience in the energy storage industry. By collaborating with industry partners, they have developed safer, smarter, and more efficient energy storage integration products. The company’s energy storage system integration products and solutions can meet the needs of various application scenarios, including combined frequency modulation for thermal power plants, energy storage supporting new energy generation, user‑side energy storage, and independent shared energy storage power stations. -
SolutionsEnergy storage is a flexible solution for mitigating grid fluctuations caused by renewable energy generation. When deployed at an appropriate scale, energy storage can effectively reduce curtailment rates of wind and solar power, enhancing the grid’s ability to absorb these sources; it can also participate in ancillary services such as peak shaving and frequency regulation, thereby generating additional revenue. -
ProductsThe company’s core business encompasses the R&D, production, and sales of large-scale energy storage system integration products, commercial and industrial energy storage products, and digital energy products, as well as the development, construction, operation, and value‑added services for energy storage power plants. -
ContactLet us join hands to overcome the technological bottlenecks in off‑grid flexible DC power supply, optimize energy storage efficiency, reduce operation and maintenance costs, and deliver clean electricity to every remote corner, jointly creating a bright future of energy inclusivity, green sustainability, and low carbon emissions.

Project Introduction
The project was put into operation on March 29 and is Hunan’s first thermal power frequency modulation energy storage battery replacement project. Without altering the original civil and electrical facilities, a high‑performance 1P liquid‑cooled DC side solution was adopted to replace the original air‑cooled battery system, optimizing the entire battery container system and significantly improving key indicators such as energy density, cell temperature control performance, and cell consistency. To meet the established series of technical specifications and on‑site requirements, while preserving core technologies like modular compartmentalization and cluster‑level temperature control, a custom‑designed 30‑foot liquid‑cooled container was developed. During the trial run, the system operated stably; thanks to the adoption of Yuanhe Energy’s cluster‑level temperature control system, under continuous 1P frequency modulation conditions, the temperature difference within each cluster did not exceed 4°C. The temperature difference between the battery cells inside the reactor does not exceed 4 degrees over 24 hours. The temperature difference between clusters is no more than 1°C, ensuring that current imbalances between clusters do not exceed 2A, thereby injecting new momentum into the Liyujiang Power Plant’s ability to achieve all its annual goals and tasks.
