What is a battery energy storage system?
A battery energy storage system (BESS) is an electrochemical device that charges from the grid or a power plant and then discharges that energy to provide electricity or other grid services when needed.
How long does a battery storage system last?
For instance, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity can provide power for four hours. The cycle life/lifetime of a battery storage system determines how long it can provide regular charging and discharging before failure or significant degradation.
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 happens if a battery is discharged too much?
For instance, if a battery is discharged to 40% of its capacity, the DOD is 60%. Exceeding the manufacturer-recommended DOD can significantly reduce the battery’s lifespan and efficiency. Operators must monitor and regulate discharges to avoid over-depleting the battery. Load management is equally important during discharging.
Who uses battery storage?
Battery storage is a technology that enables power system operators and utilities to store energy for later use.
How does the state of charge affect a battery?
The state of charge greatly influences a battery’s ability to provide energy or ancillary services to the grid at any given time. Round-trip efficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
