Energy storage is a collection of methods used to store electrical energy on large scale within an electrical power grid. Electrical energy is stored when production is stored when production (especially from intermittent power plants such as renewable electricity sources such as wind power, tidal power and solar power) exceeds consumption, and returned to the grid when production falls below consumption. Generally speaking, energy storage is economical when the marginal cost of electricity varies more than the costs of storing and retrieving the energy plus the price of energy lost in proc…More Info
