6 FAQs about [Energy storage system discharge time]

What is storage duration?

Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity. For instance, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours.

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.

What is the cycle life of a battery storage system?

Cycle life/lifetime is the amount of time or cycles a battery storage system can provide regular charging and discharging before failure or significant degradation. 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.
