Grid Energy Storage

Introduction. Grid energy storage is a collection of methods used to store energy on a large scale within an electricity grid. Electrical energy is stored at times when electricity is plentiful and cheap (especially from variable renewable energy sources such as wind and solar), or when demand is low, and later returned to the grid when demand is high and electricity prices tend to be higher.

OverviewRoles in the power gridFormsEconomicsSee alsoExternal links

Any electrical power grid must match electricity production to consumption, both of which vary significantly over time. Energy derived from solar and wind sources varies with the weather on time scales ranging from less than a second to weeks or longer. Nuclear power is less flexible than fossil fuels, meaning it cannot easily match the variations in demand. Thus, low-carbon electricity without storage presents special challenges to electric utilities.
