Grid energy storage
OverviewRoles in the power gridFormsEconomicsSee alsoExternal links
Grid energy storage (also called large-scale energy storage) is 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 variable renewable energy sources such as wind power and solar power) or when demand is low, and later returned to the grid
Assessing operational benefits of large‐scale energy storage in power
