Compare electricity providers in Denison, Texas

Denison shops retail electricity on Oncor. Choose Texas Power does not publish a Denison city page, so the average below is a dated third-party snapshot. The city bills water, sewer, and refuse.

Research on this page last updated 2026-09-30. Texas competitive retail electric market; city utility line amounts on our estimate page use separately dated sources.

Results are address-specific, and plan availability, usage credits, fees, and contract terms can change the total. Review the provider's Electricity Facts Label and Terms of Service before enrolling.

Utility Rates may receive compensation when you use this comparison tool. Compensation does not change our city utility research, source selection, or editorial explanations. We are not your retail electric provider; enrollment, if you continue, is a contract with the provider named in the offer. See our privacy policy and terms.

How this connects to our Denison utility estimate

On our Denison utility cost page, we model Oncor Electric Delivery delivery pass-throughs plus an illustrative retail supply component for competitive areas—useful for budgeting city services together. The modeled all-in electric estimate at 1,000 kWh is about $151.10 /month using our last source refresh (2026-09-30). Live REP rates you can enroll in will differ from that illustration.

Gatby’s Denison snapshot, dated October 1, 2026 and covering Oncor ZIPs including 75020, lists an average of 15.11¢/kWh at 1,000 kWh, with offers from about 6.6¢. Oncor’s September 2026 residential delivery is $4.06 per month plus 6.0295¢/kWh. Confirm a live Electricity Facts Label. That snapshot is one day after this page’s September 30 verification date.

City utility rates as of December 1, 2025: a 1-inch or smaller residential water minimum is $36.73 and includes the first 1,000 gallons, then $4.3387 per 1,000 from 1,000 to 5,000 gallons. At 5,000 gallons water is $54.08.

Oncor versus a Denison electricity plan

Oncor delivery is regulated and the same for every REP on that meter.

The 15.11¢ figure is Gatby’s October 1, 2026 snapshot, not a Choose Texas Power city page and not your contract price.

How to compare a Denison electricity offer

  • Use ZIP 75020 and confirm Oncor

    Grayson County has co-op pockets. The shopping page applies where the bill says Oncor.

  • Do not treat 15.11¢ as a PUCT city average

    Choose Texas Power has no Denison page. Re-quote on Power to Choose.

  • Water and sewer use the December 1, 2025 schedule

    At 5,000 gallons, water is $54.08 and a 5,000-gallon sewer average is $60.03.

  • Refuse is $31.53 with tax

    That is the standard residential cart. Carry-out is $46.35 including tax.

Moving to Denison

  • Confirm the meter is Oncor, not a Grayson County co-op.
  • Ask how the sewer average is set for a new account.
  • Shop the live EFL. There is no Choose Texas Power Denison page to bookmark.

Official references we use for governance context

Utility Rates matched the City of Denison utility-rate and refuse pages, and Gatby’s October 1, 2026 Denison electricity average, on 2026-09-30, because Choose Texas Power has no city page. The comparison module on this page is not a live enrollment tool.

Optional future enhancement: U.S. EIA Open Data API (free key) can layer state average retail price context with machine-readable citations once we wire a server-side fetch on revalidate.

Frequently asked questions

That site does not publish a Denison city page. Use Power to Choose with ZIP 75020.
Gatby listed 15.11¢/kWh at 1,000 kWh in a snapshot dated October 1, 2026. Oncor delivery is $4.06 per month plus 6.0295¢/kWh.
The utility-rate page adds the water minimum, the sewer minimum, and standard refuse to $110.46. A 5,000-gallon comparison is higher because volume charges apply above the first 1,000 gallons.
No. The comparison module is not a live plan feed.
In most cases, no. For a standard switch between competitive retail electric providers on an existing residential meter, your new provider and your transmission and distribution utility (TDU) typically coordinate the change electronically—an appointment at your home is not usually required simply to change supply companies. A technician may need access for new service, suspected meter or equipment problems, or safety-related orders from the utility; those are different from completing enrollment through a shopping or comparison flow. Your confirmation email and terms from the enrolling provider will say if anything non-routine applies. If no visit is mentioned, you can ordinarily expect the switch to proceed without someone entering your home.
