According to CCTV reports, China is building 70 pumped-storage power stations in operation, which have become super new energy “charging treasures”.
Pumped hydro storage refers to the use of wind power, photovoltaics and other clean energy sources to pump water to the mountains when electricity consumption is low, and then release water to generate electricity when electricity consumption peaks. This conversion process also solves the problem that electric energy has always been difficult to store. Therefore, pumped storage power stations can also be called super “charging treasures”. At present, the installed capacity of a single pumped-storage power station in my country and the total installed capacity of the country rank first in the world.
Among them, Hebei Fengning Pumped Storage Power Station is the world’s largest installed pumped storage power station, with a total installed capacity of 3.6 million kilowatts, a total investment of more than 19.2 billion yuan, and a total of 12 pumped storage generator sets installed. According to the person in charge of the power station, its reservoir capacity is 45 million cubic meters, and it can store nearly 40 million kilowatt-hours of electricity when it is fully charged at one time.
Fengning Pumped-storage Power Station is to build reservoirs on the mountain and below the mountain. Through grid dispatching, when the electricity consumption is low, the surplus wind power and photovoltaic energy are used to pump water to the mountain; when the electricity consumption peaks, the water is released to generate electricity, which not only saves the surplus The clean energy is stored, and it is also the stabilizer, regulator and balancer of the power system.
Up to now, there are 70 pumped-storage power stations under construction and in operation in the State Grid operating area, with an installed capacity of 85.24 million kilowatts, 3.2 times and 4.1 times that of 2012, respectively. It is expected that the installed capacity will reach 100 million kilowatts by 2030.
