Oncor Electric Delivery Coverage Area and Choosing a Provider

Written By: David Cosseboom | Updated On: November 12th, 2025

Compare electricity, natural gas, water, internet, and trash companies for your home.


Quick Facts:
  • Oncor delivers power but doesn’t sell it. They maintain Texas’ grid (poles, lines, outages), but you’ll need a Retail Electric Provider (REP) to supply your electricity.
  • Delivery charges appear on every bill. These fees (set by the state) are the same no matter which REP you choose.
  • Outage support is Oncor’s job. Report outages via their app, text (OUT to 66267), or call (888-313-4747).
  • Avoid “Provider of Last Resort” rates. If you don’t pick a REP, Oncor becomes your default supplier at higher, non-competitive rates.

Oncor Electric Delivery is the largest transmission-and-distribution utility (TDU) in Texas. It owns and maintains the poles, wires, substations, and meters that physically deliver electricity to homes and businesses. Oncor does not sell retail electricity plans, that job belongs to Retail Electric Providers (REPs). On a typical bill, Oncor’s portion appears as “delivery,” “wires,” or “TDU” charges because your REP passes Oncor’s regulator-set delivery fees through to you without markup.

Oncor is majority-owned indirectly by Sempra and minority-owned by Texas Transmission Investment LLC. In recent company updates, Sempra highlighted that strong Texas growth, especially data centers and large industrial loads in North Texas, continues to drive Oncor’s grid expansion plans.

Oncor’s Coverage Area

Oncor serves over 10 million Texans across a massive 122,000-square-mile territory, including major metros like Dallas, Fort Worth, Waco, Midland, Odessa, and parts of East Texas. Whether you’re in a bustling city or a quiet rural community, chances are Oncor is working behind the scenes to keep your electricity flowing.

What does Oncor do?

What Kind of Energy Does Oncor Deliver?

Oncor delivers electricity generated from a mix of sources, primarily natural gas, wind, and solar, thanks to Texas’ diverse energy grid. Oncor’s electricity comes from a wide range of generators across the ERCOT (Electric Reliability Council of Texas) market. Recent ERCOT analyses show renewables rising quickly, with wind and solar supplying roughly a third of generation and solar growing especially fast, while natural gas remains the largest single source. In 2024–2025 reporting, solar’s share increased materially and wind remained a major contributor to the Texas mix. While Oncor doesn’t produce power, they ensure it gets to your home efficiently. If you’re passionate about green energy, many REPs offer 100% renewable plans, and Oncor’s infrastructure supports that clean energy delivery.

Renewable energy and conservation efforts

As a wires-only utility, Oncor’s biggest sustainability lever is investing in grid infrastructure that supports more renewable interconnections and battery storage, and improving efficiency and reliability for customers. Company and market updates emphasize substantial capital plans to expand transmission and distribution in step with rapidly growing demand, which enables large amounts of new wind, solar, and storage to connect to the ERCOT system.

Oncor’s long-running efficiency portfolio, smart thermostat promotions, HVAC and insulation incentives, and low-income weatherization, helps reduce overall energy use and peak demand in its territory. These programs are implemented through vetted providers and are updated each year based on funding and regulatory guidance.

Choosing a Retail Electric Provider (REP)

Since Oncor Electric Delivery only handles power transmission (not sales), selecting the right Retail Electric Provider (REP) is the key to controlling your electricity costs, service quality, and even your environmental impact. Here’s why choosing a REP matters, and how to pick the best one for your needs.

1. Avoid High “Provider of Last Resort” (POLR) Rates

If you don’t actively choose a REP, you’ll automatically be placed with Oncor’s emergency backup service (POLR), which charges higher, non-competitive rates. By selecting your own REP, you can:

  • Lock in lower market prices
  • Avoid surprise rate hikes
  • Access better customer service
Pro Tip: Never rely on POLR, always shop for a plan!

2. Get Competitive Pricing & Plan Flexibilit

REPs offer a variety of plans to fit different budgets and lifestyles:

  • Fixed-Rate Plans: Price stays the same for 12-36 months (great for budgeting).
  • Variable-Rate Plans: Fluctuates with market prices (riskier but no long-term contract).
  • Prepaid Plans: Pay-as-you-go electricity (no credit check, but higher per-kWh costs).
  • Free Nights/Weekends: Discounted or free power during off-peak times (ideal for EV charging).

Example: A fixed-rate plan at 12¢/kWh could save you hundreds per year vs. POLR’s 15¢+ rates.

3. Choose Renewable Energy (If You Want It)

Want to support wind or solar power? Many REPs offer:

  • 100% Renewable Plans: Sourced from Texas wind/solar farms.
  • Green Energy Certificates: Offset traditional power with renewable credits.
  • Solar Buyback Programs: Earn credits for excess solar panel energy.

Eco-Friendly Pick: Providers like Gexa Energy and Champion Energy specialize in clean energy plans.

4. Access Better Customer Service & Perks

Not all REPs are created equal! The right provider can offer:

  • 24/7 Customer Support (vs. POLR’s bare-bones service).
  • Mobile Apps for billing and usage tracking.
  • Loyalty Rewards (bill credits, smart thermostats, etc.).
  • No Hidden Fees (some REPs waive deposits or cancellation fees).

Top-Rated REPs: TXU Energy and Reliant score well for customer satisfaction.

5. Customize Your Plan for Your Home’s Needs

  • High-Usage Homes: Look for tiered rates or free-night plans.
  • Apartments/Renters: Month-to-month or no-deposit options.
  • Smart Homes: REPs with energy management tools (like usage alerts).

  • Contract length (fixed-rate vs. variable-rate)
  • Renewable energy options (if going green is a priority)
  • Customer reviews (some REPs have better service than others)
Pro Tip: Always read the Electricity Facts Label (EFL) before signing up—it breaks down the true cost per kWh!

Final Tips for Energy Plan Shoppers

  • Watch for seasonal rate changes (summer can be pricier).
  • Avoid “teaser rates” that spike after a few months.
  • Consider bundling (some REPs offer perks like smart home devices or bill credits).

Outages: How to Search and How to Report

Oncor maintains a near-real-time Outage Map and status tools. You can search by address or view area-wide conditions. For reporting and updates, you have multiple options:

  • Call Oncor at 888-313-4747.
  • Text OUT to 66267 (ONCOR) if you’re enrolled in MyOncor Alerts.
  • Report online via Oncor’s outage reporting portal.
  • Use the MyOncor Mobile App to report and track status.

Oncor notes that its online map refreshes with new outage information about every 10 minutes, with slower refreshes during heavy traffic.

The MyOncor App: Power at Your Fingertips

The MyOncor app (iOS and Android) lets you report outages, view status updates, manage alerts, and access outage resources in one place. If you prefer text alerts without the app, you can enroll by texting REG to 66267.

Oncor Rebates, Discounts & Incentives

Oncor funds a suite of energy-efficiency programs branded under Take A Load Off Texas. These include instant discounts on smart home devices (like smart thermostats), and incentive programs delivered through participating service providers for insulation, HVAC upgrades, and other efficiency improvements. Programs generally run seasonally and funding is limited each year.

Oncor also runs a Residential Solar program that, in 2025, required paired battery storage and set incentive caps by system size. Program funds can and do sell out; the 2025 residential solar funding was reported as exhausted. Commercial solar incentives are available as well, with eligibility and size limits. Check current program manuals for the latest rules and budgets since they’re refreshed annually.

Check their Energy Efficiency Programs page for current offers, it’s an easy way to cut costs!

Oncor makes sure your electricity arrives safely, your job is just to pick the right REP for your needs. With a little research, you can find a plan that saves money, fits your lifestyle, and maybe even helps the planet.

FAQs About Oncor

What does Oncor do?

Oncor Electric Delivery is the largest electricity transmission and distribution company in Texas, responsible for maintaining power lines, poles, substations, and other infrastructure that deliver electricity to homes and businesses. While Oncor does not sell electricity plans directly to customers (that’s handled by Retail Electric Providers, or REPs), they ensure that the power you buy from your REP reaches you safely and reliably. Essentially, Oncor is the backbone of the Texas power grid in its service areas, including major regions like Dallas-Fort Worth, Midland, Odessa, and parts of East Texas.

What are Oncor Electric Delivery charges?

If you look at your electricity bill, you’ll see two main components:

Supply Charges (from your REP for the actual electricity).
Delivery Charges (from Oncor for maintaining and operating the grid).

These delivery fees cover the cost of power lines, transformers, emergency repairs, and grid upgrades. They are regulated by the Public Utility Commission of Texas (PUCT), meaning Oncor cannot arbitrarily raise rates without approval. While you can’t shop around for lower delivery charges (they’re the same no matter which REP you choose), you can reduce costs by using energy-efficient appliances or taking advantage of Oncor’s rebate programs.

How can I check for a power outage?

If your lights go out, Oncor provides multiple ways to check outage status:

Online Outage Map: Visit Oncor’s Outage Map for real-time updates on outages in your area.
Mobile App: Download the free Oncor Outage Alert app (iOS/Android) to track restoration progress.
Text Alerts: Sign up for outage notifications by texting REG to 66267.
Phone: Call Oncor’s automated outage line at 1-888-313-4747 for recorded updates.

The map and app often provide estimated restoration times, so you can plan accordingly.

How can I report an outage?

If your power is out and it’s not showing on the outage map, you should report it immediately. Here’s how:

Text: Send OUT to 66267 (if you’re registered for alerts).
Call: Dial 1-888-313-4747 and follow the prompts.
App/Website: Use the Oncor app or website to submit an outage report.
Social Media: DM Oncor on Twitter (@Oncor) for non-emergency assistance.

Pro Tip: If you see downed power lines, stay far away and call Oncor or 911 immediately, never assume a downed line is safe!

Does Oncor offer any rebates or energy-saving programs?

Yes! Oncor provides incentives to help customers reduce energy use and lower bills:

Smart Thermostat Rebates: Get up to $50 back for installing a Nest, Ecobee, or other eligible thermostat.
HVAC & Insulation Rebates: Save on energy-efficient upgrades.
LED Lighting Discounts: Discounts on bulbs through partnered retailers.
Energy Efficiency Programs: Free home energy audits and tips.

Why is my bill higher even though Oncor doesn’t sell electricity?

Since Oncor handles delivery (not supply), rate changes usually come from your REP. However, delivery charges can fluctuate slightly due to:

Grid maintenance or storm recovery costs (approved by PUCT).
Increased usage (e.g., extreme weather leading to more power demand).
TDU (Transmission & Distribution) fee adjustments (passed through from Oncor to your REP).

If your bill spikes, compare your REP’s rate and check your kWh usage first.

Can I choose Oncor as my electricity provider?

No, Oncor is not a retail provider. You must select a REP (like TXU, Reliant, or Gexa) to supply your electricity. The only exception is if your REP fails and Oncor becomes your Provider of Last Resort (POLR), which is rare and comes with higher default rates. Always actively choose a REP to avoid POLR pricing.
