Energy Storage Fact Sheet

A demand charge is applied to end users who have the largest energy demands (e.g., large multifamily and apartment buildings; commercial, industrial, education-al, industrial, and healthcare facilities; etc.). For many commercial customers, the demand charge can account for 30% to 70% of a monthly electricity bill. How can an energy storage
