Understanding how much energy your appliances use will help you determine the best way to manage your energy usage while on the Time-of-Day Rate. While use of some appliances can’t be shifted, such as a refrigerator, you can save by using appliances like a clothes washer, dryer or dishwasher during off-peak hours, and by managing how much or when appliances like dehumidifiers and heating and cooling systems run.

You may also want to think about investing in ENERGY STAR® qualified appliances. ENERGY STAR appliances incorporate advanced technologies and use 10 to 50 percent less energy than standard appliances. Minnesota Power offers rebates on energy-efficient appliances; click here to learn more.

Average Home Energy Costs

The (expandable) tables below give you a basis for estimating appliance operating costs. These figures are based on energy consumption of typical appliances, their average use and Minnesota Power’s average residential customer cost of 9.1 cents per kilowatt-hour (kWh). Your cost per kWh may vary depending on how much energy you use and when you use it. Your appliances and use patterns will also vary.

Estimating Your Appliance Operation Costs

You can use the calculator tools below to help you estimate what it costs to operate your specific appliances,

Or you can calculate these costs yourself if you have the right information:

Calculating the Cost of an Appliance

All electric appliances have the “wattage” or “amperage,” and “voltage” indicated somewhere on the unit (amps x volts = watts). You can use this figure to determine your cost of operation. For example, you can determine how much it would cost to operate an electric space heater with 1,500 watts for 3 hours using the following calculations:

1,500 watts/1,000 = 1.5 kW
1.5 kW x 3 hours = 4.5 kWh
4.5 kWh x 9.1 cents/kWh = 40 cents
