Dual Fuel Calculator

To use this calculator, you'll need to 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.
• The price you paid for that fuel.

This 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% of the time and the back-up system 10% of the time to provide heating during energy control.

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