Demand is the rate of energy consumption per unit of time. It is the sum of the wattage requirements of all electric devices operating at a given time and is measured in kilowatts.

With an RDC installation customers establish a demand setting at which to operate their home during control periods. Demand settings usually range from 3 kilowatts to 6 kilowatts but may be as high as 8 kilowatts.

Customers pay a set energy rate per kilowatt-hour used plus a demand charge based on the highest kilowatt reading that is metered during a winter control period during the last 12 months.
