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.

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 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 power stations maximize power balance of regional power grid?

The existing literature shows that pumped storage power stations can maximize the power balance of regional power grid, ensure the safe and stable operation of regional power grid, and realize the economic optimization of power grid operation through reasonable modeling and new energy distribution schemes.

Are independent energy storage stations a good investment?

This does not augur well for the market in terms of long-term competition. There will be safety risks associated with excessive cost control and an indifference to quality. Independent energy storage stations enjoy good long-term prospects, though this segment is sluggish in the short term.

How can pumped storage power stations improve water resource utilization?

The development of small and medium-sized pumped storage power stations, combined with existing reservoirs, can increase the utilization rate of surrounding pump stations, channels and other water-conserving equipment and maximize the development and utilization of water resources.
