Use this calculator to estimate your household’s electric demand and learn how the timing of appliance use can affect your peak demand.

Demand is the amount of electricity your home requires at a specific point in time when appliances and equipment are running. It reflects the highest level of electricity use at one time.

For purposes of this calculator, the demand shown for each appliance assumes that appliance is running during the same one-hour period. This helps illustrate how using several appliances at once can increase your household’s total demand.

Please note that actual appliance demand may vary based on the age, size, model, and efficiency of each device.
