This is defined in Eq. (1), where the total energy transferred into ( Ein) or out of ( Eout) the system must equal to the change in total energy of the system (Δ Esystem) during a process. This indicates that energy cannot be created nor destroyed, it can only change forms. (1) E in − E out = Δ E system.

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 intermittent power sources such as renewable electricity from wind power, tidal power and solar power) or when demand is low, …
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
