Estimated for a typical home from Tarrant County weather (NOAA climate normals 1991–2020) and how Texas homes use electricity as the weather changes (U.S. EIA). The model is not a city meter reading or a prediction for your home. Prices are interpolated between the published 500/1,000/2,000 kWh points; outside that range the nearest endpoint is used. Each benchmark point can come from a different plan, so the annual total is not an available annual contract price. Taxes, future rate changes and exact EFL fee thresholds are not modeled. How we estimate
Homes in Colleyville
23% of the 9,072 households in Colleyville heat with electricity, fewer than the Texas average of 61%. The heating mix helps explain why your winter electricity use may differ from a county-wide weather model; it does not predict a bill for an individual home. 3% of households rent, and half the homes were built before 1994.
| Measure | Colleyville | Texas |
|---|---|---|
| Homes heated with electricity | 23% | 61% |
| Homes heated with natural gas | 76% | 35% |
| Households that rent | 3% | 37% |
| Single-family houses | 98% | 67% |
| Mobile homes | 0% | 6% |
| Median year built | 1994 | 1992 |
| Median rooms per home | 10.0 | 5.4 |

Questions people ask
How do I find cheap electricity in Colleyville?
Compare the total bill at the usage level closest to your own recent readings. The lowest-cost fixed-rate offers above exclude usage credits, prepayment and time-of-use pricing. Check the current Electricity Facts Label, contract length and cancellation fee before enrolling; a low price at 1,000 kWh may not be cheapest at 500 or 2,000 kWh.
What is the best electric company in Colleyville for my home?
There is no single best electricity provider for every household. Compare costs at your actual usage, contract terms and the provider’s complaint record. The cheapest-plan summary ranks listed costs, not customer service. Your retail provider sells your plan and handles billing; the delivery company maintains the wires.
How much does electricity cost in Colleyville?
The typical plan costs 13.3¢ per kWh at 1,000 kWh a month, about $133 for the month including Oncor delivery. Fixed-rate plans without bill credits start at 10.1¢.
Can I choose my electricity provider in Colleyville?
For addresses eligible for retail choice in the Oncor delivery area, yes: 43 providers offer 173 listed plans. Oncor delivers power whichever provider you choose. Confirm the delivery company and plan availability at your exact address; some addresses in or around Colleyville may have different service.
Why do some plans show a very low price?
Some plans include a bill credit that applies only when usage meets a condition. Missing the credit can raise the average price even when you use less electricity. The amount and threshold vary by plan. Untick “Hide plans with bill-credit tricks” to inspect these offers and check the EFL.
