Energy storage technologies help the grid (electric distribution system) handle peaks in demand. Generally these occur once or twice daily. When the energy storage is located near the load (a major city or industry) it can ameliorate problems with security or reliability of linear infrastructure. Storage helps economic dispatch by allowing more efficient power generators to charge energy for peak loads.
