Deferred Load 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 based on your past use of fossil fuels and apply the Deferred Load Rate for your state.

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