Dual Fuel calculator

Calculate your potential dual fuel savings

Better understand whether dual fuel is the right choice with this simple-to-use energy calculator.

To use this calculator, you'll need to know:

• The age or efficiency of your present heating system.
• The amount and type of fuel you've used over a one-year period.
• The price you paid for that fuel.

This tool will calculate your Btu requirements and apply the small Dual Fuel Rate for your state.

Our Dual Fuel calculator estimates that electricity will be used 90% of the time and the back-up system 10% of the time to provide heating during energy control. Otter Tail Power Company's dual fuel rate averages about half the standard price of electricity making it one of the lowest-priced electric rates available.

Rate calculations include rates, adjustments, and riders effective September 2019.
