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. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the

Pumped-storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir.

Hence, to suppress such fluctuations, energy storage is essential. Pumped hydro storage (PHS) in this context is one of the most attractive choices due to high efficiency, reliability and low cost. This paper discusses the use of PHS for removing the intermittency in supplies from solar and wind energy.
The efficient methods (like batteries, pumped storage, and flywheels) retrieve 90% of the energy, but are very limited in terms of how much energy they can store. The large-scale methods (like chemical storage) can store virtually unlimited amounts of energy but are very inefficient (75% losses).
The International Forum on Pumped Storage Hydropower is co-chaired by Malcom Turnbull, former Australian Prime Minister, and Kelly Speakes-Backman, Acting Assistant Secretary for Energy Efficiency and Renewable Energy at the U.S. Department of Energy. Several international governments and regulators comprise the steering committee.
Pumped storage hydropower has proven to be an ideal solution to the growing list of challenges faced by grid operators. As the transition to a clean energy future rapidly unfolds, this flexible technology will become even more important for a reliable, affordable and low carbon grid, write IHA analysts Nicholas Troja and Samuel Law.
Efficiency and the price of electricity for storing energy greatly influence short-term storage, and this is lessened for long-term storage. In relative terms, however, as a maximum the change in LEC is only 19%.
The thermal stores are arranged vertically, as shown, so as to prevent buoyancy-driven instabilities of the thermal fronts. The energy is stored as ''sensible heat'', enabling efficient integration with the thermodynamic cycle and avoiding the ''pinch-point'' difficulties associated with phase-change storage methods.
25 kinds of pumped thermal energy storage systems are presented and assessed. Configuration selection maps for high power-to-power efficiency are developed. Energy storage density and levelized cost of storage evaluation are carried out. Higher energy storage density is achieved by employing latent thermal storage.
