What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability of a battery energy storage system (BESS), or the maximum rate of discharge it can achieve starting from a fully charged state. Storage duration, on the other hand, is the amount of time the BESS can discharge at its power capacity before depleting its energy capacity.
How long can a battery store and discharge power?
The storage duration of a battery is determined by its power capacity and usable energy capacity. For example, a battery with 1MW of power capacity and 6MWh of usable energy capacity will have a storage duration of six hours.
