How to Use the Oncor Outage Map and Report Power Outages?

If you live in North Texas, West Texas, or parts of Central and East Texas, an Oncor power outage can affect your home, business, internet, appliances, and daily routine. Severe storms, high winds, ice, vehicle accidents, equipment issues, and local grid damage can all interrupt electric service.
The good news is that the Oncor outage map makes it easier to check power outage status, identify affected areas, and view estimated restoration times. Oncor also offers ways to report outages and receive alerts. In this guide, we'll explain how to use the map, understand outage updates, report a problem, and prepare your home with reliable backup power solutions.

Quick Answer

To check a power outage, use the official Oncor outage map to view affected areas, outage status, and estimated restoration times. The map is updated every 10 minutes, although delays may occur. You can report an outage online, call 888-313-4747, or text OUT to 66267 if you're enrolled in MyOncor Alerts. Home backup power systems can also help keep essential appliances running during an outage.

What Is Oncor?

Oncor Electric Delivery is a regulated electricity transmission and distribution utility in Texas. It maintains the infrastructure that delivers electricity to customers, including power lines, poles, meters, substations, and other grid equipment.
Oncor does not generate electricity or sell retail electricity plans directly to customers. Instead, it operates and maintains the transmission and distribution infrastructure that delivers electricity to homes and businesses.
This distinction matters in Texas because many customers can choose a Retail Electric Provider (REP) for their electricity plans. Your REP typically handles billing and electricity rates, while Oncor manages power lines, meters, outage restoration, and local electricity delivery within its service area.

What Is Oncor’s Service Area?

Oncor serves a large part of Texas, including areas across North Texas, West Texas, Central Texas, and parts of East Texas. Its service territory includes cities such as Dallas, Fort Worth, Arlington, Plano, Irving, Waco, Killeen, Midland, Odessa, Wichita Falls, Tyler, and surrounding communities. Oncor also provides an official service area map to help customers check whether their addresses fall within its delivery territory.
Because Texas has multiple transmission and distribution utilities, not every power outage in the state is an Oncor outage. Some areas are served by CenterPoint Energy, AEP Texas, Texas-New Mexico Power, or other utilities. If you're unsure which utility serves your address, check your electricity bill for your transmission and distribution utility (TDU).

How Frequent Are Oncor Power Outages?

There is no single fixed number for how often an Oncor power outage happens because outages depend on weather, location, equipment, vegetation, traffic incidents, and grid conditions. Many outages are local and short, while major storms can create widespread interruptions.
For example, severe weather in March 2025 caused more than 335,000 outages at its peak across Oncor’s system, according to Oncor's official report. During a winter storm in January 2026, CBS Texas reported that about 8,700 Oncor customers were without power on the morning of January 26, with most outages concentrated in East Texas due to ice and wind damage.
While major outages may not occur every day, Texas weather can cause sudden and significant power disruptions. Even localized outages can affect daily activities, especially when electricity is needed for heating, cooling, refrigeration, or communication. Staying informed about local outage conditions and having a backup power plan can help households prepare for unexpected interruptions.

Common Causes of Oncor Power Outages

Oncor power outages can occur for various reasons, ranging from severe weather to equipment failures and accidental damage. Understanding these causes can help residents recognize potential risks and prepare for unexpected power interruptions.
  • Severe Weather: Thunderstorms, lightning, high winds, hail, tornadoes, and heavy rain can damage power lines, poles, transformers, and nearby trees. Severe spring storms are a common cause of widespread power outages in Texas, sometimes leaving large numbers of customers without electricity until damaged equipment can be repaired.
  • Ice and Winter Storms: Ice accumulation can weigh down trees and power lines, causing branches to fall and electrical equipment to fail. Freezing temperatures, icy roads, and hazardous driving conditions can also delay restoration efforts, making winter storm outages particularly challenging in affected areas.
  • Vehicle Accidents: Cars and trucks can collide with utility poles, transformers, or other electrical equipment, causing localized power outages. These incidents may require emergency repairs or equipment replacement before electricity can be safely restored to affected homes and businesses.
  • Equipment Failure: Transformers, cables, switches, breakers, and other grid components can fail due to aging, overheating, electrical faults, or physical damage. Depending on the location and severity of the failure, these problems may disrupt electricity for a few customers or an entire neighborhood.
  • Trees and Vegetation: Tree branches can come into contact with power lines during storms or high winds, potentially damaging equipment or interrupting electricity service. Although regular vegetation management helps reduce these risks, falling trees and branches remain a common cause of localized outages.

How Do You Check the Oncor Power Outage Map?

The Oncor outage map is a useful tool for checking power outages across Oncor’s service area. It shows affected locations, the number of customers without power, and estimated restoration times when available. You can access the official map through Oncor’s outage page to check current conditions in your area.
To use the Oncor power outage map:
  1. Visit the official outage map: Go to Oncor’s outage map to view reported power outages.
  2. Find your area: Zoom in on the map or browse outage information by ZIP code, city, or county.
  3. Check affected customers: Select an outage marker to view the number of customers affected and other available details. Markers generally indicate the location of affected electrical equipment rather than individual homes.
  4. Review restoration estimates: Check the estimated restoration time, if available, to see when power may return. If no estimate is available, the map may display "Currently Unknown."
  5. Check your specific outage: Use Oncor’s Check Outage Status tool if you need information about your service address.
  6. Get outage alerts: Sign up for MyOncor Alerts to receive outage notifications and restoration updates.
According to Oncor, outage information is sent to the map every 10 minutes, although updates may take longer during periods of heavy website traffic. Estimated restoration times may also change as crews assess damage and complete repairs. If your power is out but your outage does not appear on the map, you can report it directly to Oncor.

How Do You Report an Oncor Power Outage?

If your power is out, you can report an Oncor power outage through several methods:
  • Report online: Visit Oncor's official outage page to report a power outage or check its status.
  • Call Oncor: Dial 888-313-4747 to report an outage by phone.
  • Send a text: Text OUT to 66267 if you're enrolled in MyOncor Alerts. To register, text REG to the same number.
  • Use the MyOncor app: Report outages and check outage information through Oncor's official mobile app.
If you see a downed power line, stay away, keep others and pets away, and call 911 immediately. Never touch or attempt to move a fallen line or anything in contact with it, as it may still be energized.

How Can You Prepare for an Oncor Electric Power Outage?

Power outages can disrupt daily routines, especially during severe storms or extreme temperatures. Preparing ahead of time can help you stay informed, protect essential supplies, and keep important devices running when electricity is unavailable. Here are some practical steps to take:
  • Prepare emergency supplies: Keep flashlights, spare batteries, drinking water, nonperishable food, a first-aid kit, and any necessary medications readily available. Store these items in an accessible location so you can find them quickly during an outage.
  • Stay informed about outages: Save Oncor's outage reporting number (888-313-4747) and bookmark the official Oncor outage map. Check for updates on affected areas and estimated restoration times, especially during severe weather.
  • Charge essential devices: Fully charge smartphones, laptops, power banks, and other important electronics before storms arrive. Keep charging cables handy and consider a battery-powered or hand-crank radio for emergency updates.
  • Protect refrigerated food: Keep refrigerator and freezer doors closed as much as possible during an outage. An unopened refrigerator generally keeps food safe for about 4 hours, while a full freezer can maintain a safe temperature for about 48 hours if the door stays closed.
  • Prepare for extreme temperatures: Keep blankets and warm clothing available during winter outages. In hot weather, stay hydrated and identify a safe, air-conditioned location you can visit if indoor temperatures become unsafe.
  • Plan for backup power: Consider home battery backup solutions to help power essential appliances, lighting, and communication devices during extended outages. Choose a system based on your household's electricity needs and expected outage duration.
If you use a gas-powered generator, always operate it outdoors at least 20 feet away from doors, windows, and vents to reduce the risk of carbon monoxide poisoning. Never run one inside your home or garage, even with the doors open.
