Important! Incentives in the Home Energy Savings program changed on March 20, 2010. Please see the Qualifications section below for more information.

Bundle up your home to save money and significantly increase comfort.

Designed to keep your home warm in the winter and cool in the summer, properly installed insulation can significantly lower your electricity bill. There are several common types of insulation – fiberglass, cellulose, rigid foam board and spray foam – all of which can help you save electricity and money. When adding insulation, make sure you know the R-value of the product you are considering. Used to measure the insulation’s thermal performance, a higher R-value will deliver more insulating power.

Homes built less than one calendar year prior to the work being performed do not qualify for the incentive. Incentives do not qualify if work is performed as part of building code requirements. Areas that are not finished living spaces, such as a garage or a basement, do not qualify. Basements must be finished living space (ducted for heating and cooling) in order to qualify for wall insulation. Only above grade portions of exterior basement walls qualify. Basement floors do not qualify. To ensure your home is below the maximum insulation depth requirements, please use the insulation depth calculator. Prior to your contractor recording measurements, take a peek in your attic and do it yourself! Insulation may be installed by the customer or contractor. Self-installers are eligible for incentives on materials only. For self-installed insulation, please provide documentation of R-Values and square footage of insulation installed. This information will be listed on your register receipt or your insulation packaging. Contractor installations require invoice and proof of payment to receive incentives. Work may be inspected. Incentive will not exceed project cost. NOTE: Greater energy efficiency can be gained by insulating to higher R-values. Recommended Levels for your geographic area are: Walls to R-21, Floors to R-30 and Attics to R-49. Work may be inspected. To find a Participating Home Improvement Contractor please use our list of Idaho Participating Home Improvement Contractors. Incentives are limited to the square footage of the qualified area of the home (wall, floor or attic).

Please see Incentive Application for a list of required documentation and additional terms and conditions. Incentives are subject to tariff approval and may change with 45 days notice. Additional terms and conditions may apply.

For self-installed insulation, please provide documentation of R-values and square footage of insulation installed. This information will be listed on your register receipt or your insulation packaging.
