The OMPA Geothermal Rebate: Up to $800 Per Ton for Kingfisher, Okeene, Watonga and Other Oklahoma Municipal Towns

I am Dave Hartzell. My shop is on Main Street in Kingfisher, and Kingfisher buys its power through its own municipal electric utility. For years this site explained what the rural electric cooperatives pay on geothermal and said nothing about what my own town pays, so a Kingfisher homeowner could read it all and think there was no rebate here. There is one.

If your electric bill comes from your city or town instead of a co-op, your program is the WISE Heat Pump Rebate Program run by the Oklahoma Municipal Power Authority, OMPA.

What OMPA is, and why the town line beats the county line

OMPA is a wholesale power authority owned by 43 municipal electric utilities across 29 Oklahoma counties. Kingfisher, Okeene and Watonga are OMPA member cities. Edmond is a member too, and it runs this rebate program.

Here is the part that trips people up: it is who sends the bill, not which county you live in. Watonga is the clearest example. It sits in Blaine County, where a rural meter can be on an electric cooperative while inside town the town’s own utility serves the meter. Same county, two rebate programs, and the envelope in your mailbox settles it.

I am not going to publish a list of which towns pay what. Membership in OMPA and participation in the rebate are two different things, both set by the town, and a stale list on a website is how a homeowner ends up disappointed. If your bill comes from your city or town rather than a co-op, call me and I will check your utility.

The published geothermal amounts

These are OMPA’s published categories for heat pumps rated at 65,000 BTU per hour or less, all paid per cooling ton of AHRI rated capacity, to the nearest hundredth of a ton. New to the word ton? Start with what a ton of geothermal actually means.

Every amount in that table is a ceiling, not a flat payment, and the categories are OMPA’s own. Which one your job lands in is something I settle with your utility, not guess at from a website.

Minimum efficiency to qualify: EER 17.1, or EER2 16.36. That is a real screen, which is why I pull the performance data on the exact model before I write the proposal.

No desuperheater, no rebate

This is the requirement that kills more of these rebates than anything else, and almost nobody knows it.

A desuperheater takes heat the system is already moving and sends it to your water heater instead of wasting it. It earns its keep on its own merits, and on a municipal utility it is the difference between qualifying and not, so I design it in from the start. Read what a desuperheater is and how one heats your water in Oklahoma.

The rest of what has to be true

• New installation, or a conversion from another type of HVAC system.
• The rebate goes to the member city or town’s electric customers. Your customer class, residential, commercial, industrial or institutional, follows the rate category your town already has you in.
• An in home energy audit is required before installation, handled case by case. Here is my geothermal energy savings audit.
• Installed by a licensed contractor, permits secured and closed. I hold a Master HVAC license and I am IGSHPA accredited for geothermal.
• Information off the data plate of the equipment coming out, or a photo of it. Easy on install day, miserable once the old unit is gone.
• Paperwork within 90 days of installation. The invoice has to show my contractor information, the model number, the purchase and installation date, and the price. The payee name has to match the billing section.

The contractor agreement is my job, not yours

A contractor agreement is required once per member city or town, not once per job. That is the kind of friction that stalls a project when nobody owns it. I own it. On your call I will tell you whether it is already in place for your town.

Oklahoma has three different rebate worlds

Which utility you are on changes your geothermal rebate by thousands of dollars. Three worlds, and they do not overlap:

• Municipal utilities. Your city or town sells you the power. That is the OMPA WISE program on this page, and Kingfisher is on it.
• Electric cooperatives. CKenergy Electric Cooperative pays $2,000 per ton on a qualifying install in its territory. It does not serve Kingfisher County, which is why the CKenergy rebate page correctly tells a Kingfisher reader that number is not theirs. That was never a statement that Kingfisher gets nothing.
• Investor owned utilities. OG&E residential rebates are closed for 2026 and return in 2027.

The full picture across the state is on Oklahoma geothermal rebates. It comes back to the same test: look at who sends the bill.

The federal residential credit is gone

The Section 25D residential geothermal credit expired: the IRS states plainly that it is not available for any property placed in service after December 31, 2025. I am not a tax professional and you should take your own situation to yours, but do not build a budget around it. Utility rebates are where the real money is in 2026, which is the reason this page exists.

I go anywhere in Oklahoma for geothermal

Geothermal is statewide work for me, not a seven county thing. I have run geothermal jobs in Kingfisher, Okarche, Hennessey, Watonga, Dover, Loyal, Cashion, Crescent, Piedmont, Edmond, Yukon, Mustang, El Reno, Guthrie, Enid, Geary, Okeene, Fairview, Thomas, Ames and Oklahoma City, and I have gone as far as Lawton, Broken Bow and Durant for a customer who wanted geothermal. There is one shop, in Kingfisher, and I drive. To be clear, that is a list of places I work, not a list of towns with a rebate. Eligibility depends on your utility, and I check it for your address.

Questions I get about this rebate

How much is the OMPA geothermal rebate in Kingfisher Oklahoma?

The program tops out at $800.00 per cooling ton for a geothermal electric heat pump, and that ceiling is not automatic. The town may rebate at any level and OMPA matches it 50/50 up to the published amount, so your town’s elected level decides what you get. I confirm it with your utility before I quote. Call 405-375-4822.

Do I need a desuperheater to get the OMPA geothermal rebate?

Yes. The system has to have at least one operating integrated water heater or desuperheater doing domestic water heating. No desuperheater, no rebate. I design it in from the beginning so qualification is never in question.

My county is on an electric cooperative but my bill comes from the town. Which geothermal rebate do I get?

The one your utility runs, which is the town’s. Who sends the bill decides it, not the county line. Watonga is the clearest case: the town serves meters inside town limits, a cooperative serves rural meters in the same county. Pull out your bill and I will tell you which program you are in.

How much does a geothermal diagnostic cost in Kingfisher Oklahoma?

$348 flat, any hour, weekday or after hours. That is a full performance check with a written report and a quote before I leave. An estimate on a new system is free.
