A grid-forming energy storage project developed by CHN Energy Guodian Power Development Inner Mongolia New Energy was selected on February 26 for the first batch of pilot projects announced by the National Energy Administration (NEA) to enhance the capabilities of building a new-type power system.
The project is located in Baotou City, Inner Mongolia Autonomous Region, with a planned site area of approximately 85.75 square kilometers, adjacent to the national border. Following the concept of coordinated development of new energy + new-type energy storage, the project plans a total capacity of 600 megawatts of green power, including 420 megawatts of wind power and 180 megawatts of photovoltaic power.
The project will be equipped with a centralized grid-forming energy storage system. The system does not rely on grid support and can independently establish voltage and frequency references while simulating rotational inertia and damping characteristics. It can operate in island mode for more than two hours to supply power, ensuring continuous electricity supply for critical loads. By improving the short-circuit ratio, the project can increase its maximum power transmission capacity by 25 percent.
After being put into operation, the project is expected to provide 1.583 billion kilowatt-hours of clean electricity annually, save about 477,100 tons of standard coal, and reduce carbon emissions by approximately 1.3104 million tons each year.
