In an electricity power system based on thermal, nuclear, hydro and renewable generation, storage will find a wide field of application and may perform various duties, which must be taken into consideration in order to gain the largest possible advantage in the supply side optimisation. An energy storage unit can be connected to the transmission, subtransmission or distribution system in a manner similar to customer-owned conventional or renewable generation facilities such as gas or wind turbines. These dispersed sources are able to change the character of a typical electricity power system completely.
