Introduction
As of 2025, according to International Hydropower Association, [4] worldwide PSH provides 200 GW power and 9000 GWh energy storage, while the Battery energy storage system market is catching up very fast in terms of power generation capacity. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. It can offer a wide range of services to the modern-day power grid, especially assisting the large-scale integration of variable energy resources. PSH complements wind and solar by storing the excess electricity they create and providing the backup for when the wind isn’t blowing, and the sun isn’t shining.
