The use of battery storage is usually designed around one of two strategies; demand shaving, or solar PV over-production. Demand shaving is a strategy which uses the selective discharge of stored battery energy to reduce or ‘shave’ the peak demand of utility power.Cutting down the maximum demand or peak during the billing month lowers the demand charge portion of the utility bill.
A BESS is an energy storage system (ESS) that captures energy from different sources, accumulates this energy, and stores it in rechargeable batteries for later use. Should the need arise, the electrochemical energy is discharged from the battery and supplied to homes, electric vehicles, industrial and commercial facilities.BESS collects energy from an electricity grid or renewable power sources, such as solar and wind, and stores it using battery storage technology.
