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 Carnot battery is a type of energy storage system that stores electricity in heat storage and converts the stored heat back to electricity via thermodynamic cycles (for instance, a turbine). While less efficient than pumped hydro or battery storage, this type of system is expected to be cheap and can provide long-duration storage.
The functionality of a seawater pressure storage power plant is based on usual pumped-hydro storage plants. A hollow concrete sphere with an integrated pump-turbine will be installed on the bottom of the sea. Compared to well known pumped-hydro storage plants, the sea that surrounds the sphere represents the upper water basin.

The availability of hydropower sites suitable for storage will vary from grid to grid. Typical round trip efficiency is 80%. [10] [70] Traditional lithium-ion is the most common type used for grid-scale battery storage as of 2020. [71] Rechargeable flow batteries can serve as a large capacity, rapid-response storage medium. [13]
The following page lists all pumped-storage hydroelectric power stations that are larger than 1,000 MW in installed generating capacity, which are currently operational or under construction. Those power stations that are smaller than 1,000 MW , and those that are decommissioned or only at a planning/proposal stage may be found in regional ...
Castaic Power Plant, the largest pumped-storage power station in California. Pumped-storage hydroelectricity is important means of large-scale grid energy storage that helps improve the daily capacity factor of California's electricity generation system. This is a list of all operational pumped-storage power stations in California.
