Large-scale energy storage


A collection of methods used for energy storage on a large scale within an electrical power grid. Electrical energy is stored during times when electricity is plentiful and inexpensive (especially from intermittent power plants such as renewable electricity sources such as wind power, tidal power, solar power) or when demand is low, and later returned to the grid when demand is high, and electricity prices tend to be higher.
