Arbitrage

Arbitrage involves purchasing inexpensive electricity when its demand and cost are low; and then selling the electricity when demand and price are high.  Storage systems that operate in this market generally have the capacity to storage large amounts of energy, interact with the power grid at the transmission level, and operate on a diurnal cycle of charge and discharge.  Examples are pumped hydro plants, compressed air electricity storage facilities, and large battery installations.
