Approval and progress analysis of pumped storage power stations in Central China during the 14th five-year plan period

During the “14th Five-Year Plan” period, China's pumped storage power stations have achieved rapid development. The country approved 110 pumped storage power stations with a total installed capacity of 148.901 gigawatts, which is 2.8 times the capacity approved during the “13th Five-Year Plan” period. China has completed 70.90 % of the total capacity target of 210 gigawatts for key implementation projects during the “14th Five-Year Plan”. Pumped storage power stations in Central China are typical for their large capacity, large number of approved pumped storage power stations and rapid approval. This paper analyzes the development of pumped storage power stations in Central China, focusing on regional approval, investment ownership, design units and cost analysis. It summarizes the current development mode and provides an analysis of pumped storage development in both Central China and China as a whole. The relevant situation is of great significance for promoting the construction of pumped storage power stations and for the construction and optimization of modern power systems.
