Large industrial electricity bills typically consist of two parts: energy charges (based on how many kilowatt-hours are consumed) and demand charges (based on transformer capacity or peak demand). Using energy storage to reduce the "monthly peak demand" directly lowers demand charges.
The energy storage system monitors the real-time power behind the customer's transformer. When it detects that the load power is about to exceed the set demand threshold, the storage system discharges rapidly to cover the excess load, thereby "shaving" the peak demand seen by the grid side.
