I am a commercial customer. What is the demand charge on my bill and how is it calculated?
Commercial/Industrial customers are billed based on their kilowatt-hour usage as well as their demand, which is measured in kilowatts (kW). Demand is the highest quantity of kilowatts registered by the meter in any 15-minute interval during the billing cycle, but not less than eighty percent of the maximum demand established during the preceding summer season (June through September) or sixty percent of the maximum demand established during the winter season (October through May). The demand charge on a commercial bill may be identical several months in a row.
