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.

A dynamic energy storage solution, pumped storage hydro has helped ‘balance’ the electricity grid for more than five decades to match our fluctuating demand for energy. Pumped storage hydro (PSH) involves two reservoirs at different elevations.
Pumped-storage schemes currently provide the most commercially important means of large-scale grid energy storage and improve the daily capacity factor of the generation system. The relatively low energy density of PHES systems requires either a very large body of water or a large variation in height.
Pumped storage provides more capacity for a hydropower system to store short term energy surpluses from other renewable sources allowing greater capture of this clean energy. What are the main advantages of pumped storage compared to other energy storage technologies?
By pumping the water uphill when generation exceeds demand, the pumped storage scheme is essentially ‘storing’ energy for later use. With the extra storage, stability and consistency provided by pumped hydro, there’s less need for coal, gas or diesel generation.
Pumped storage power stations operate using two water reservoirs at different elevations. They can operate the turbines to generate electricity during peak demand periods, while the water is pumped back up from the lower reservoir to the higher reservoir during off-peak times.
