Rocky Mountain Power is one of the few investor-owned utilities running a heat pump rebate program across two entire states with materially different policy environments. The wattsmart incentive structure looks similar on paper in Utah and Wyoming, but the stacking math, eligibility windows, and contractor-network rules diverge in ways that change a homeowner's net cost by thousands of dollars.
This guide walks the program as it stands going into the 2026 rebate cycle, with an eye toward what stacks, what doesn't, and which sequencing mistakes cost households the most money. For broader context on layering utility, state, and federal incentives, our rebate stacking application order guide is the companion piece.
What are Rocky Mountain Power heat pump rebates?
Rocky Mountain Power's wattsmart program offers cash rebates to residential customers in Utah and Wyoming who install qualifying air-source or ground-source heat pumps. Rebate amounts vary by equipment type, efficiency tier, and whether the install replaces electric resistance or fossil-fuel heating, and they are claimed through the utility's contractor network.
Why Rocky Mountain Power Is a Different Kind of Utility Rebate
Most utility rebate guides assume a single-state regulator and a single integrated resource plan. Rocky Mountain Power, a PacifiCorp subsidiary, serves customers across Utah, Wyoming, and Idaho under three different public utility commissions — each with its own demand-side management filings and cost-recovery mechanisms.
That regulatory split is why the wattsmart rebate schedule looks slightly different at the Utah and Wyoming borders. The program name is the same, the application portal is the same, but the approved measures and rebate tiers are filed separately and approved on different calendars.
For homeowners, the practical effect is that a Utah customer and a Wyoming customer installing the identical Mitsubishi or Bosch heat pump in the same week may receive different rebate amounts. Always confirm the current schedule on the wattsmart portal before signing a contract.
The Utah Side: wattsmart Rebates in Context
Utah's regulatory environment leans toward measured, ratepayer-funded efficiency programs administered through approved trade allies. Rocky Mountain Power's Utah rebates have historically covered ducted air-source heat pumps, ductless mini-splits, and ground-source (geothermal) systems, with tiered amounts based on equipment efficiency.
Cold-climate-rated equipment generally qualifies for higher rebates than standard ASHP units, particularly in the northern half of the state. If you're sizing in the Wasatch Back or anywhere above 6,000 feet, our cold-climate heat pump sizing guide covers why the equipment selection drives both rebate amount and operating cost.
Utah also runs additional state-administered electrification programs separate from the utility rebate. The federal HEEHRA rollout in Utah is tracked on our HEEHRA state-by-state status page and may be available for income-qualified households on top of the wattsmart rebate.
Can Utah homeowners stack wattsmart with HEEHRA?
Yes, in most cases. The wattsmart rebate is a utility ratepayer-funded incentive, while HEEHRA is a federally funded, state-administered program. They are not the same funding source, so income-qualified Utah households can typically combine both, plus the federal 25C tax credit, provided each program's documentation requirements are met.
The Wyoming Side: Smaller Population, Different Math
Wyoming's wattsmart program covers similar equipment categories but operates under a different cost-recovery framework approved by the Wyoming Public Service Commission. Rebate amounts have historically tracked Utah's schedule closely but are not guaranteed to remain identical year to year.
Wyoming homeowners face an additional consideration: many homes outside Casper, Cheyenne, and Jackson are well-suited to dual-fuel configurations where a heat pump handles shoulder-season loads and a propane or natural gas furnace handles the deepest cold-snap hours. Whether that approach qualifies for the full rebate depends on the equipment category claimed.
For homeowners weighing a dual-fuel install, our heat pump backup heat guide walks through the sizing math and explains why the backup-heat decision is upstream of the rebate decision, not downstream.
How the Stack Actually Works
The stacking sequence matters more than most homeowners realize. Federal tax credits, utility rebates, and any applicable HEEHRA funds are claimed in different ways, on different timelines, and with different documentation — and one of them affects the basis used to calculate another.
How do you stack Rocky Mountain Power rebates with federal credits?
Apply for the wattsmart rebate first through your approved contractor, document the rebate amount received, then claim the federal 25C tax credit on the net cost (equipment plus install, less the utility rebate). HEEHRA, if available in your state and you qualify by income, is applied at point of sale and similarly reduces the basis for 25C.
The IRS guidance on this point has shifted over the past two years. Our what happened to 25C in July 2025 explainer covers the most recent program changes and what they mean for rebate-basis calculations going into the 2026 filing year.
Equipment That Qualifies for wattsmart
Rocky Mountain Power maintains a published list of qualifying equipment, generally aligned with the AHRI directory and Energy Star certified products. Rebate tiers are typically defined by SEER2 and HSPF2 thresholds, with higher payments for cold-climate-designated systems.
| Equipment Type | Typical Rebate Tier | Best Fit |
|---|---|---|
| Ducted ASHP, standard | Base tier | Mild climates, replacing electric resistance |
| Ducted ASHP, cold-climate | Mid to upper tier | Northern Utah, most of Wyoming |
| Ductless mini-split | Per indoor head or per outdoor unit | Additions, zoned retrofits, no existing ducts |
| Ground-source heat pump | Highest tier | Larger lots, long-term ownership horizon |
Verify the current tier amounts on the wattsmart portal before assuming any specific dollar figure — these schedules update with each PUC filing cycle. Contractor quotes that include a specific rebate amount should match the published schedule.
The Contractor-Network Requirement
Rocky Mountain Power requires installations to be performed by approved trade allies for the rebate to be paid. This is the single most overlooked rule in the program, and it disqualifies more applications than any equipment-spec issue.
If you have a preferred HVAC contractor who is not in the wattsmart network, two options exist: ask the contractor to apply for trade ally status before signing a contract, or choose a different installer. Retroactive enrollment after the install is generally not allowed.
Common Sequencing Mistakes
Three mistakes account for most denied or reduced rebates. Each one is avoidable with a phone call to the utility before signing anything.
Sequencing pitfalls to avoid:
- Signing the contract before pre-approval. Some wattsmart measures require pre-qualification of the equipment and contractor before work begins.
- Mixing rebate-eligible and rebate-ineligible equipment on one invoice. The utility needs a clean line-item showing the qualifying equipment cost.
- Claiming the federal 25C credit on the gross install cost rather than the post-rebate net. The IRS treats utility rebates as a reduction in basis for the credit calculation.
What to Do If You're Comparing Air-Source and Ground-Source
Ground-source heat pumps qualify for the highest wattsmart rebate tier in both Utah and Wyoming, and they also qualify for a separate, larger federal tax credit under section 25D. The combined incentive stack on a GSHP install can exceed the stack on an equivalent ASHP install by a meaningful margin.
That said, the up-front cost differential is large, and the payback math depends on heating load, electricity rates, and how long the homeowner expects to stay in the home. Our air vs ground source comparison walks through when the ground loop is worth it and when an ASHP plus a smaller stack of rebates is the better answer.
Does a ground-source heat pump qualify for both wattsmart and federal credits?
Yes. Ground-source heat pumps qualify for the highest wattsmart rebate tier and also qualify for the federal section 25D residential clean energy credit, which historically covered 30% of the system cost. Confirm current percentages and any caps with the IRS guidance and your tax preparer before relying on a specific figure.
Income-Qualified Pathways
Households below certain income thresholds may qualify for additional support through HEEHRA, state weatherization programs, or local non-profits. The HEEHRA layer is particularly important because it can cover up to 100% of project cost for the lowest-income tier, dramatically changing the stacking math.
For a walkthrough of how the income tiers work, our HEEHRA income tiers explained guide covers the AMI brackets, what documentation is required, and how the point-of-sale rebate interacts with the tax credit.
Are wattsmart rebates available to renters or landlords?
Rocky Mountain Power's wattsmart program is generally available to the customer of record on the electric account, which in most rental situations is the tenant for the utility piece but the property owner for the equipment install. Coordination between landlord and tenant is required, and some rebate categories are owner-occupied only — verify with the program before applying.
Timing the Application
Rebate budgets are approved annually and can be exhausted before the year ends in high-demand programs. Rocky Mountain Power has not historically run out of wattsmart funds mid-year, but program rules and budgets can change with each rate case filing.
Homeowners planning a 2026 install should confirm the current rebate schedule before signing a contract and submit the application as soon as the install is complete. Delays of more than 90 days between install and application can sometimes void the rebate.
Decision Rule for Most Homeowners
If you live in Rocky Mountain Power service territory in Utah or Wyoming, are replacing an aging furnace or electric resistance system, and plan to stay in the home at least five years, the wattsmart-plus-25C stack is usually the right starting point. The ground-source upgrade makes sense on larger lots with longer ownership horizons.
If your household is income-qualified for HEEHRA in either state, the calculation shifts substantially — the federal point-of-sale rebate can dominate the stack and may make cold-climate equipment effectively free. See our 25C vs HEEHRA decision tree to figure out which federal pathway fits your situation.
How much can I get back from Rocky Mountain Power for a heat pump?
Rebate amounts depend on equipment type, efficiency tier, and the state you live in. Standard ducted air-source heat pumps qualify for a base-tier rebate, cold-climate-rated ducted systems qualify for a higher tier, and ground-source heat pumps sit at the top of the schedule. Specific dollar amounts are published on the wattsmart portal and update with each public utility commission filing, so verify before signing any contract.
Do Utah and Wyoming wattsmart rebates have the same amounts?
The two states' programs use the same name and similar structure but are filed separately under the Utah and Wyoming public utility commissions. Rebate amounts have historically tracked closely but are not guaranteed to match year to year, and approved measures can diverge. Always check the schedule for your specific state on the wattsmart portal before assuming a specific figure.
Can I use any HVAC contractor for the wattsmart rebate?
No. Rocky Mountain Power requires installations to be performed by approved trade allies for the rebate to be paid. If your preferred contractor is not in the network, ask them to apply for trade ally status before you sign a contract, or choose an enrolled installer. Retroactive enrollment after the work is complete is generally not allowed and is the most common reason rebate applications are denied.
How does the wattsmart rebate affect my federal 25C tax credit?
The IRS treats utility rebates as a reduction in the basis used to calculate the federal 25C credit. Practically, that means you claim the credit on the net cost — equipment and install minus the utility rebate — not the gross invoice amount. Keep clean documentation showing the rebate amount received and the post-rebate net for your tax preparer.
What if I want a dual-fuel system instead of an all-electric heat pump?
Dual-fuel systems pairing a heat pump with a fossil-fuel backup can qualify for the wattsmart rebate, but the rebate tier may be different than for an all-electric configuration. The federal 25C credit also has specific eligibility rules around backup heat. Work with your contractor to confirm both the utility and federal eligibility before committing to a dual-fuel design, because the equipment-selection decision is upstream of the rebate decision.
