Dual Fuel Calculator

To use the calculator, first gather information about your present heating system and your energy costs. You'll need:

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

The tool will calculate your Btu requirements and apply the Small Dual Fuel Rate for your state.

Note: Our dual fuel calculator estimates that electricity will be used 90 percent of the time and the back-up system 10 percent of the time to provide heating during energy control.

Rate calculations include rates, adjustments, and riders effective May 2016.
