This information is based on current annualized average monthly retail charges for ComEd electric delivery service and ComEd supply service at 13.76 cents per kilowatt-hour to residential customers in Illinois using rates applicable beginning with the June 2018 billing period. Actual savings may vary based on usage and rates. Wattages shown are averages. Specific factors such as equipment efficiency, hours of use, operating conditions, etc. can cause actual operating costs to vary. Many appliances “cycle” from a running to an idle mode affecting the amount of electricity they use.
