Oncor Power Outage: How to Check, Report, and Prepare
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 Oncor offers several ways to check outage status, report a problem, and receive alerts. In this guide, we’ll explain what Oncor is, where it operates, how often outages happen, how to use the Oncor power outage map, and how backup power solutions can help you stay prepared.
Quick Answer
To check an Oncor power outage, use the official Oncor outage page, where you can report an outage, check status, sign up for alerts, and open the outage map. You can also report an outage by calling 888-313-4747 or texting OUT to 66267. In addition, home backup systems can greatly help with emergency preparedness.
What Is Oncor?
Oncor Electric Delivery is a regulated transmission and distribution utility in Texas. That means Oncor maintains the electric delivery infrastructure, including power lines, poles, meters, substations, and related grid equipment.
Note that it does not generate electricity or sell retail electricity plans directly to customers. Instead, it delivers electricity from generation facilities through transmission and distribution lines to homes and businesses.
This distinction matters in Texas because many customers choose a Retail Electric Provider, or REP, for their electricity plan. Your REP handles billing and plan pricing, while Oncor handles the wires, outage restoration, meter service, and local electric delivery in its service area.
What Is Oncor’s Service Area?
Oncor serves a large part of Texas, including major 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 provides an official service area map for customers who want to confirm whether their address is within its delivery territory.
Because Texas has multiple transmission and distribution utilities, not every Texas outage is an Oncor outage. For example, some areas are served by CenterPoint, AEP Texas, Texas-New Mexico Power, or other utilities. If you are unsure, check your electric bill for your TDU or delivery provider.
How Frequent Are Oncor Power Outages?
There is no single fixed number for how often an Oncor electric 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 utility-industry reporting on Oncor’s restoration response. During a winter storm in early 2026, CBS Texas reported that about 8,700 Oncor customers were without power at one point, with many outages localized in East Texas because of ice and wind damage.
So, while most days may not involve a major outage, Texas weather can create sudden and significant disruptions.
Common Causes of Oncor Power Outages
Oncor power outages can happen for many reasons. Some are weather-related, while others come from local equipment or accidental damage.
Severe Weather
Thunderstorms, lightning, high winds, hail, tornadoes, and heavy rain can damage power lines, poles, transformers, and trees near electrical equipment. In Texas, severe spring storms are a common reason for widespread outages.
Ice and Winter Storms
Ice can weigh down trees and power lines, while cold weather and hazardous road conditions can slow restoration crews. Oncor’s storm updates have noted that road conditions and vehicle accidents can affect outage response during severe weather.
Vehicle Accidents
Cars and trucks can strike poles, transformers, or other electric equipment. Oncor has noted that public vehicle accidents can damage its equipment and contribute to power outages during hazardous conditions.
Equipment Failure
Transformers, cables, switches, breakers, and other grid components can fail because of age, heat, overload, or damage. These issues may affect a small area or a larger section of the distribution system.
Trees and Vegetation
Branches can contact power lines during storms or high winds. Vegetation management helps reduce risk, but falling limbs remain a common cause of local outages.
