The project is located in Dengkou County, Bayannur City, and adopts a hybrid technology route of "all vanadium flow battery+lithium iron phosphate battery". Among them, the all vanadium flow battery system is a technology demonstration project of Inner Mongolia Autonomous Region's "unveiling and leading" initiative. Its energy efficiency reaches 80% when the rated current density of a single cell is 500 milliamps per square centimeter, and the system energy efficiency is higher than 72%. Its performance indicators are significantly better than industry standards.
It is reported that with the strong assistance of the local government, the project completed the construction task efficiently in just 80 days from the official start of construction to grid connected charging and discharging. Energy storage power stations have dual attributes of load and power supply, which can play a role in peak shaving, valley filling, supporting power grid operation, promoting the consumption of new energy, and improving the utilization rate of wind and solar resources. They are a key link in promoting the coordinated integration of electricity and energy consumption, industrial development, and power grid system. "said Ma Quanshan, project leader of Dengkou Energy Storage Power Station of Mengneng New Energy Company.

At present, Inner Mongolia Energy Group New Energy Company has built a photovoltaic project with an installed capacity of 4.45 million kilowatts in Dengkou County. After the energy storage project is put into operation, it will significantly enhance the regional new energy consumption capacity and the stability of the power system, expand the development space for local sand prevention and control and wind power photovoltaic integration projects, and provide important support and demonstration for the construction of a "new type of power system integrating source, grid, load and storage" in Inner Mongolia Autonomous Region.
