Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

EERA Joint Program SP4 - Mechanical Storage Pumped Hydro Energy Storage (PHES) plants are a particular type of hydropower plants which allow not only to produce electric energy but also to store it in an upper reservoir in the form of gravitational potential energy of the water.
Another perspective to understand the scale of the area requirement for pumped hydro energy storage is to compare to the land needed for the associated generation. A solar farm with a daily output of 1 GWh requires an area of land that is about 300 Ha (assuming 18% efficient modules, a capacity factor of 16%, and a module packing density of 50%).
The pumped hydro energy storage (PHES) is a well-established and commercially-acceptable technology for utility-scale electricity storage and has been used since as early as the 1890s.
The construction of reservoirs and dams can alter local ecosystems, affecting water flow and wildlife habitats. High Initial Costs: Setting up a pumped storage hydropower system involves substantial initial investment. The costs of constructing reservoirs, dams, turbines, and generators can be prohibitive, impacting the feasibility of new projects.
