Customer ServiceRated Power Capacity is the total discharge capability (usually in megawatts (MW)) or the maximum rate of discharge the BESS can achieve, starting from a fully charged state. Rated Energy Storage Capacity is the total amount of stored energy in kilowatt-hours (KWh) or megawatt-hours (MWh). Capacity expressed in ampere-hours (100Ah@12V for example).
The amount of discharged energy per cycle depends on the rated energy of the storage system (E), its efficiency (η), and its depth of discharge (dod). Moreover, the discount factor (df) and discount rate (dr) decrease the discharged energy per year . Therefore, the total discharged energy during the system lifetime is
