In January 2026, China's largest all vanadium liquid flow energy storage power station achieved full capacity operation in Jimsar County, Xinjiang, marking a key breakthrough in the large-scale application of high-capacity long-term energy storage technology in China. The project is a 1 million kilowatt photovoltaic+20 million kilowatt/1 million kilowatt hour all vanadium liquid flow energy storage integration project, with a total investment of over 1.9 billion yuan. The energy storage capacity is equivalent to the total amount of one-time charging for more than 16000 60 degree battery pure electric vehicles, setting a record for the largest scale of similar projects in China.

As a stabilizer for new energy generation, the all vanadium flow technology installed in this energy storage power station has multiple core advantages: the water-based electrolyte is inherently safe and has no risk of fire or explosion; The cycle life can reach 20000 times, and it can operate stably for about 25 years, far exceeding traditional lithium batteries; The power and energy units can be flexibly split, and expansion only requires increasing the electrolyte storage capacity, perfectly adapting to large-scale long-term energy storage scenarios. Its core working principle achieves reversible conversion of electrical and chemical energy through changes in the valence state of vanadium ions, with a charge discharge state switching time of only 0.02 seconds and extremely fast response speed.

After the project is put into operation, it will have significant energy regulation and ecological benefits: the annual power generation can reach 1.72 billion kilowatt hours, saving about 519000 tons of standard coal and reducing carbon dioxide emissions by more than 1.42 million tons per year. During the period of high photovoltaic power generation, the power station can store excess electricity to alleviate the pressure of power grid consumption; During peak electricity consumption or periods without light, electricity is released to achieve "peak shaving and valley filling", effectively smoothing out the volatility of new energy generation and significantly reducing the rate of wasted solar energy, laying a solid foundation for the efficient utilization of Xinjiang's abundant solar energy resources.

This project is not only a fully domestically produced and controllable demonstration project, but also provides valuable practical experience for the development of China's energy storage industry. Based on the 560000 acres of new energy planning land in Jimsar County, the project will help build a 10 million kilowatt level new energy base in the local area and promote the formation of a regional green and low-carbon industrial system. Under the guidance of the "dual carbon" target, its successful model will provide reference for the construction of a new national power system, accelerate the transformation of the energy storage industry from policy driven to market driven, and inject strong impetus into the energy structure transformation.Editor/Bian Wenjun
