Utah window rebates from Rocky Mountain Power and Enbridge Gas can genuinely help offset the cost of a window replacement project, but the two programs work differently and it’s worth understanding both before you apply. Our energy-efficient window solutions meet the certification standards required to qualify for these programs.
Rocky Mountain Power’s Wattsmart Program
Rocky Mountain Power’s Wattsmart Homes program offers cash rebates on qualifying window replacements for residential electric customers in Utah on approved rate schedules (1, 2, or 3), including landlords whose tenants are billed on those same schedules. Your home must be an existing single-family or manufactured home, new construction doesn’t qualify, and electric heating or central electric cooling must serve at least 80% of the home’s conditioned floor area.
The program was updated effective February 27, 2026, shifting from a per-square-foot rebate structure to a per-window structure, so it’s worth confirming the current rebate amounts directly with the program rather than relying on older figures. Windows can be installed by a program-participating contractor or self-installed, though different documentation requirements apply depending on which route you take. Our professional window installation services can help you navigate the documentation requirements for either path.
Enbridge Gas’s ThermWise Program
Enbridge Gas, formerly known as Dominion Energy Utah, offers a separate rebate through its ThermWise Weatherization program, available to residential customers on the general service rate schedule across Utah, Idaho, and Wyoming. This program pays a rebate based on square footage of qualifying window area installed, and it runs independently of Rocky Mountain Power’s program.
Because the two programs come from different utilities and are structured differently, eligible homeowners with both electric and natural gas service may be able to apply to both programs for the same project. Our full lineup of replacement windows includes options that qualify for both rebate programs.
Qualifying Windows & U-Factor Requirements
Both programs generally require ENERGY STAR certified windows meeting a specific U-factor threshold, commonly 0.22 or lower, though it’s worth confirming current requirements directly with each program since qualification standards can be updated. Our Window Energy Ratings Explained guide covers what U-factor and other NFRC ratings actually mean, useful background before you start comparing specific window products against these requirements. Our ENERGY STAR Window Shopping Checklist guide covers the fuller list of what to verify before buying.
Stacking Rebates & How to Apply
Since Wattsmart and ThermWise are independent programs from different utilities, it’s often possible to apply to both for the same project if you qualify for each. Required documentation typically needs to be submitted through each program’s online portal within a set window after project completion, commonly around 180 days, so don’t delay paperwork once your windows are installed. Working with a program-participating or authorized contractor can also simplify the application process, since they’re often familiar with current documentation requirements.

Making the Most of Utah’s Window Rebates
Rocky Mountain Power’s Wattsmart program and Enbridge Gas’s ThermWise program are both real, currently active ways to offset the cost of a window replacement project, but eligibility, documentation, and rebate amounts vary and are subject to change. Confirming current program details directly before you commit to a specific window product is the best way to make sure your project actually qualifies.
