. The energy is later converted back to its electrical form and returned to the grid as needed. Most of the world's grid energy storage by capacity is in the form of pumped-storage hydroelectricity, which is covered in
List of pumped-storage hydroelectric power stations The following page lists all pumped-storage hydroelectric power stations that are larger than in installed generating capacity, which are currently operational or under construction. Those power stations that are smaller than , and those that are ...
. This article list plants using all other forms of energy storage. Another energy storage method is the consumption of surplus or low-cost energy (typically during night time) for conversion into resources such as hot water, cool water or ice, which is then used for heating or cooling at other times when electricity is in higher demand and at greater cost per kilowatt hour (kWh). Such
thermal energy storage Thermal energy storage (TES) is achieved with widely different technologies. Depending on the specific technology, it allows excess thermal energy to be stored and used hours, days, months later, at scales ranging from the individual process, ...
