Battery storage is a technology that enables power system operators and utilities to store energy for later use.
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.
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. 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.
While lithium-ion batteries have dominated the energy storage landscape, there is a growing interest in exploring alternative battery technologies that offer improved performance, safety, and sustainability .
Many factors afect the energy capacity rating and as the battery is often the most expensive com-ponent within a BESS, its sizing can significantly impact the cost-efectiveness of any solution. Even so, the energy storage industry does not yet have a common lexicon for discussing the end use energy capacity of a storage facility.
Lithium-ion batteries employed in grid storage typically exhibit round-trip efficiency of around 95 %, making them highly suitable for large-scale energy storage projects .
