Many utilities impose demand charges on their commercial customers. These are driven by single peaks of consumption and can represent over 40% of a monthly bill.
A well designed and integrated PV/storage system can eliminate most of that.
There are a few critical points to take into account before adding storage to a system:
1) Currently, shaving off demand charges by shifting load to batteries is the main reason for moving forward; the technology and pricing are not yet aligned for backup to be cost effective,
2) Sizing calculations are complex and must be accurate to achieve maximum savings.
