These systems integrate renewable solar photovoltaic (PV) or wind energy and hydroelectric energy with energy storage technologies, including lithium-ion batteries or pumped hydro storage. . An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety. . Growing levels of wind and solar power increase the need for flexibility and grid services across different time scales in the power system. Currently, the huge expenses of energy storage is a significant constraint on the economic viability of wind-solar integration. Both energy sources operate in a complementary manner, with wind power usually being more productive on cloudy days or during the night, while solar power is best utilized. .
