Technical FAQs 4

Why are small and medium-sized pumped storage power stations important?

Small and medium-sized pumped storage power stations have unique development advantages, and the development and construction of small and medium-sized pumped storage power stations have important practical significance for optimizing the energy structure of Zhejiang Province.

How to choose a pumped storage power station?

The site selection for small and medium-sized pumped storage power stations is flexible, and the site has low requirements for terrain and geological conditions and good adaptability. Transmission roads have low construction requirements and easy access to electrical systems.

How pumped storage power station can reduce the cost?

Therefore, on the basis of conventional small hydropower, the transformation into a small pumped storage power station or joint operation with pumped storage can reduce the cost, shorten the construction period, solve the problem of site selection, improve the power station output in the dry season, and increase the economic benefits.

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).
