Utah ThermWise vs Wattsmart in 2026 — What Homeowners Actually Qualify For
How Dominion gas programs and Rocky Mountain Power electric programs differ, and why fuel type drives your insulation rebate stack.
If you heat with natural gas, you live in Dominion Energy’s world for many weatherization rebates. If you cool and heat with a heat pump or lean electric, Rocky Mountain Power’s Wattsmart catalog is usually the first stop. The programs are not interchangeable — measure names, verification steps, and caps differ.
Start with your fuel type, then map attic R-value, air sealing, and wall insulation as separate line items. Programs often require minimum R-level jumps and blower door thresholds. Stack federal tax documentation with utility paperwork, but never assume a blog table from 2023 still matches this quarter’s tariff.
