Electrical Demand is the amount of electricity in kilowatts (kW) that the house is using simultaneously at any given time. The more appliances that are run together, the larger the demand is.
For example, the average air conditioner uses 4 kW of demand and the average clothes dryer uses 3.5 kW of demand. When the air conditioner and clothes dryer are run simultaneously in a home, the demand of the home will be 7.5 kW.
