Dallas Electricity Rates (2025) — Oncor Service Territory
5 minute read · Local market guide
Dallas is served by the Oncor Electric Delivery service territory — the largest TDSP in Texas, covering Dallas, Fort Worth, Arlington, Plano, and most of the DFW Metroplex. With more than 60 retail providers competing across the Oncor territory, Dallas residents have access to some of the most competitive electricity rates in the state.
Is Dallas in the deregulated electricity market?
Yes — Dallas is fully within the deregulated ERCOT electricity market. All ZIP codes in the 75201–75254 range for Dallas proper are eligible, as are suburbs across Dallas, Tarrant, Collin, and Denton counties (Plano 75023–75094, Frisco 75034–75035, Irving 75038–75063, Garland 75040–75044, McKinney 75069–75071, and dozens more).
Not all Texas cities have this option. Austin is served by Austin Energy, a city-owned utility — Austin residents cannot choose their electricity provider. San Antonio is served by CPS Energy, also a municipal utility. El Paso is outside ERCOT entirely. If you are unsure whether your address is eligible, entering your ZIP code in the search above will confirm availability instantly.

Dallas electricity usage by season
Dallas has hot summers and mild-to-cold winters. Unlike Houston, Dallas can see meaningful heating costs in December and January. Typical usage:
| Season | Typical Usage | Primary Driver |
|---|---|---|
| Summer (Jun–Sep) | 1,200–1,800 kWh | Air conditioning |
| Fall/Spring | 700–900 kWh | Minimal HVAC |
| Winter (Dec–Feb) | 900–1,300 kWh | Heating |
Why Dallas rates can differ from other Texas cities
All Texas electricity bills include a regulated TDSP delivery charge — and Oncor's delivery charge differs from CenterPoint's (Houston), AEP's, and TNMP's. Since the TDSP charge is fixed regardless of provider, Dallas and Houston customers will see different all-in rates even if their retail provider charges the same energy rate.
This is why comparing plans using Texas Energy Compare — which shows the full all-in rate including delivery charges — gives you a more accurate picture than looking at energy-only advertised rates.
Tips for Dallas electricity shoppers
- Check rates 45 days before contract expiration — this gives you time to compare without pressure. Set a calendar reminder.
- Compare at your actual usage level — use the 500, 1,000, or 2,000 kWh toggle on Texas Energy Compare that matches your typical bill.
- Avoid rolling to month-to-month — if your fixed contract expires without renewal, you'll often automatically move to a high variable rate.
