During the “Twelfth Five-Year Plan” and “Thirteenth Five-Year Plan” periods, to adapt to the rapid development of new energy and UHV power grids, pumped storage power stations such as Fengning in Hebei Province and Jixi in Anhui Province ushered in a new peak.
Energy storage stations have different benefits in different scenarios. In scenario 1, energy storage stations achieve profits through peak shaving and frequency modulation, auxiliary services, and delayed device upgrades . In scenario 2, energy storage power station profitability through peak-to-valley price differential arbitrage.
Introduction Pumped storage power station is a kind of hydropower station with energy storage function. It uses surplus electricity during periods of low power demand to pump water from a lower reservoir to a higher one.
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”.
Before the 14th Five-Year Plan, the development of pumped storage power stations in China was mainly carried out by power grid enterprises, namely State Grid Corporation and China Southern Power Grid Corporation.
Analysis of the investment composition proportion of two pumped storage power stations in the Central China region. According to Table 6, the total investment required to construct a pumped storage power station is approximately 9 billion yuan. The static total investment of the project accounts for about 82 % of the total investment.
