FAQS about Discharge capacity of energy storage power station
What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
What is the scale of an energy storage power station?
For example, the scale of an energy storage power station is 500KW/1MWh, where 500KW refers to the maximum charge and discharge power of the energy storage system, and 1MWh refers to the system capacity of the power station.

What is power capacity (mw)?
Power Capacity (MW) refers to the maximum rate at which a BESS can charge or discharge electricity. It determines how quickly the system can respond to fluctuations in energy demand or supply. For example, a BESS rated at 10 MW can deliver or absorb up to 10 megawatts of power instantaneously.
What is energy capacity?
Energy Capacity (MWh) indicates the total amount of energy a BESS can store and subsequently deliver over time. It defines the duration for which the system can supply power before recharging is necessary. For instance, a BESS with an energy capacity of 20 MWh can provide 10 MW of power continuously for 2 hours (since 10 MW × 2 hours = 20 MWh).
What is storage duration?
Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity. For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours.
