To promote the construction of pumped storage power stations, it is of great significance for the construction and optimization of modern power systems. 2. Development trends of pumped storage energy in China To effectively support the construction and development of pumped storage power stations, China has issued a series of supporting policies.
Under the background of “dual carbon”, pumped storage is ushering in unprecedented development opportunities. With the continuous increase in the scale and proportion of renewable energy in China, it is becoming more and more important to improve the peaking capacity of the power system through pumped storage power stations.
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.
This implies a major shift in energy storage investors to state-owned enterprises (SOEs) from power grid companies such as China Energy, Huaneng, Huadian, and State Power Investment Corporation (SPIC) .
This supports utility-scale energy storage plants for power peak load management by offering cost reductions to power grid companies through T&D tariffs, renewable energy development funds (i.e., 0.019 yuan/kWh), and miscellaneous expenses.
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.
