Energy storage can be used for power quality control, energy cost saving and demand management in a variety of fields.

1 EES for Power Plant §  Utility solution (1~500MW) §  Relatively slow response time, ramp rate §  Energy storage for power companies, inde

pendent power plant

2 EES for T&D §  Utility solution (0.5kW~50MW) §  Fast response time, ramp rate §  Transmission congestion relief §  Frequency regulation

3 EES for End User §  Residential and commercial solution (1kW~

10MW) §  Energy cost saving §  Demand management

4 EES for Renewables §  Power Quality Control solution (1~500MW) §  Relatively fast response time, ramp rate
