Why do we need pumped storage power stations in Zhejiang?
Vigorously developing and building small and medium-sized pumped storage power stations is an important measure to solve the current imbalance in energy development in Zhejiang, and it is also an important measure to attract capital investment, ensure local electricity safety, and create a demonstration and pilot zone for common prosperity.
What are pumped storage units?
Characteristics of technology Traditional pumped storage units typically use synchronous motors, meaning the generator and turbine must maintain a constant speed to synchronize with the grid. Consequently, these units are referred to as fixed-speed units.
Can pumped storage stations be used as energy storage support?
With China continuously scaling up the construction of integrated clean energy bases like “hydro-wind-storage” and new energy bases such as “Shagohuang”, pumped storage stations, especially variable-speed ones, will be more widely applied as energy storage support in regional grids (China Power, 2023).
Does China need pumped storage?
China's installed capacity of pumped storage ranks first in the world, and there are many small power grids in many places, which puts forward higher requirements for the development of small and medium-sized pumped storage.
How many pumped storage stations are there?
Out of the 38 pumped storage stations already in operation, these two enterprises own 33 of them, accounting for a combined capacity of up to 93 %.
Should pumped storage power stations be planned according to local conditions?
In 2021, the National Energy Administration made it clear in the Medium and Long Term Development Plan for Pumped Storage (2021–2035) that the construction of small and medium-sized pumped storage power stations should be planned according to local conditions in provinces with better resources.
