The economic evaluation of small and medium-sized pumped storage power stations is an important means to evaluate the construction and operation costs of power stations. Economic evaluation includes the evaluation of investment cost, operation cost and economic benefit of power station.
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.
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.
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.
Given the rapid growth of the new energy industry, energy storage stations have become a focal point for investors, thanks to their efficient energy utilization and environmental benefits.
