If you've lived in Dallas for more than a year, you've already experienced a power outage caused by something other than a once-in-a-decade event. Summer thunderstorms with straight-line winds, ice storms that coat power lines, and a grid that's working harder than ever to keep up with North Texas's growth all make outages a normal part of life here, not a rare emergency.
This guide covers what's actually driving outage risk in Dallas-Fort Worth right now, plus the concrete steps you can take to keep your home running when the power does go down.
Why Dallas Outages Are More Likely Now Than Ever Before
For most of the last decade, the story of the Texas grid was about a single brutal season: summer. That's no longer accurate. ERCOT, which manages the grid for roughly 90% of the state including all of DFW, has confirmed that 2025 set an all-time winter peak demand record of 80.6 gigawatts in February — in the same year that summer demand reached 83.9 gigawatts. The grid is now under sustained pressure in two seasons instead of one.
Several factors are converging to put real strain on the system as time goes on:
- Explosive data center and large-load growth. The Energy Information Administration projects ERCOT-wide electricity demand will rise roughly 14% in 2026, driven largely by data centers and cryptocurrency mining facilities coming online. ERCOT entered 2026 with more than 230 gigawatts of large-load interconnection requests in its queue, nearly four times the prior year's level.
- Hotter nights, longer AC demand. Texas's overnight low temperatures have been rising, which means air conditioners that used to get a break after sunset are now running well into the night. ERCOT's own data shows the tightest grid conditions increasingly occur in the evening hours — typically around 9 p.m. — rather than at the traditional afternoon peak.
- Record demand forecasts. ERCOT's modeling for summer 2026 anticipates new all-time demand records. While ERCOT puts the probability of an actual grid emergency at a low single-digit percentage for any given month, "low probability" is not "no risk," and that statistic doesn't capture weather-driven, localized outages, which are far more common than statewide grid emergencies.
The Bigger, More Common Risk: Severe Weather
For the average Dallas homeowner, a statewide ERCOT emergency is actually less likely to affect you than a severe thunderstorm, ice storm, or high-wind event, because those happen multiple times a year and can knock out power locally even when the broader grid is fine.
Oncor, which delivers electricity to more than 4 million homes and businesses across North and Central Texas, has responded to several major outage events just in the past year:
- In March 2025, a severe storm system with straight-line winds of 75–80 mph swept across the DFW Metroplex, knocking out power to more than 335,000 customers at its peak, with the hardest-hit areas — McKinney, Irving, and Farmers Branch — taking days to fully restore.
- In May 2025, a Memorial Day weekend storm system brought 50-60 mph winds with gusts near 70 mph across the Oncor service area, triggering another wave of outages right as families were trying to enjoy the holiday.
- In January 2026, a winter storm caused prolonged outages across Oncor's territory as ice accumulation weighed down tree limbs and snapped them onto power lines — a pattern that repeats almost every winter in North Texas.
The takeaway: you don't need a historic grid collapse to lose power in Dallas. A normal severe weather season will do it, possibly more than once a year.
5 Ways to Prepare Your Home For A Power Outage
1. Build a Real Emergency Kit, Not a Token One
The basics still matter, but an appropriate emergency kit should go further than flashlights and batteries:
- Flashlights and headlamps in every main room, with fresh batteries (headlamps are genuinely more useful than flashlights for hands-free work)
- A battery-powered or hand-crank radio so you can follow severe weather updates without relying on a phone
- A portable battery bank or two, fully charged, dedicated to keeping phones operational — cellular service is your most reliable communication channel in an extended outage
- A first aid kit, since outages often coincide with the kind of conditions (downed trees, ice, debris) that cause injuries
- A manual can opener and at least three days of non-perishable food and water per person — official guidance has consistently recommended a minimum 72-hour supply
- Cash on hand. Card readers and ATMs don't work without power, and during widespread outages, the businesses that do stay open often can't process electronic payments
If you're on a private well, remember that most well pumps are electric, so a multi-day outage means no running water unless you've planned around it with stored water or backup power for the pump.
2. Backup Power: What's Actually Realistic for Dallas Homes
This is the area where the most has changed since older guidance was written, and where the biggest mistakes happen.
Portable Generators
A portable generator is the lower-cost entry point, but it requires careful, code-compliant setup to be safe.
- Never run a portable generator inside a garage, basement, or enclosed space, even with the door open. Carbon monoxide from generator exhaust is a leading cause of injury and death during outages. The Consumer Product Safety Commission recommends placing generators at least 20 feet from doors, windows, and vents, with the exhaust pointed away from the home.
- Never plug a generator directly into a wall outlet. This is one of the most dangerous and surprisingly common mistakes homeowners make. Doing so can backfeed electricity into the grid, creating a serious electrocution risk for the Oncor lineworkers who may be working on what they believe is a de-energized line, possibly miles from your home.
- A portable generator needs either a manual transfer switch or an interlock kit to safely connect to your home's panel. Both require a permit and licensed electrician installation under NEC Article 702, which governs optional standby systems. The transfer switch must be UL-listed and physically prevent the utility and generator power from ever being connected to the same circuit simultaneously.
Whole-Home Standby Generators
Standby generators, which are permanently installed units that detect an outage and switch on automatically, are an increasingly common investment for Dallas homeowners given how frequently the area experiences both summer storms and winter freezes.
A few things worth knowing if you're considering one:
- Texas law protects your right to install one, even if you live in a community with an HOA. Under Texas Property Code § 202.019, an HOA cannot prohibit a homeowner from installing a standby generator rated at least 7 kilowatts, though it can impose reasonable rules about placement, screening, and noise.
- Permits are required. The City of Dallas requires an electrical plan review for generator installations, including one-line electrical drawings, a load analysis, and specifications for the generator, transfer equipment, and fuel storage. If your installation uses more than 100 gallons of LP gas stored outside, or more than 10 gallons of gasoline, additional Flammable Liquid Permits apply.
- Your electrical panel needs to be able to handle it. Older Dallas homes, particularly those with panels rated below 150 amps, often need a panel upgrade before a standby generator can be safely added. See our Electrical Panel Upgrade service if you're unsure where your home stands.
- An automatic transfer switch (ATS) is what makes it "automatic." Without one, you still need to manually start the generator and switch over circuits, which defeats much of the convenience. Our team installs and inspects ATS systems as part of standby generator setups; learn more by reaching out through our Electrical Installation page.
Either way, generator installation is not a DIY project. Beyond the legal licensing requirement, the consequences of a mistake range from a denied insurance claim to a fatality among utility workers restoring power in your neighborhood.
3. Protect Your Electronics from Surge Damage
Power outages are frequently followed by power surges when service is restored, and Dallas's storm-driven grid makes this a near-annual event for many homes. A whole-home surge protector installed at your main panel protects everything in the house simultaneously, rather than relying on individual surge strips that only protect what's plugged into them.
The current National Electrical Code (the 2023 NEC, adopted by the City of Dallas in 2025) requires surge protection devices at the main panel for many new installations and renovations, a reflection of how seriously surge risk is now taken at the code level. If your home doesn't already have one, see our Surge Protection page, and read Everything About Surge Protection in the Dallas Market for more detail on how it works.
In the meantime, when an outage hits: unplug sensitive electronics, such as computers, TVs, gaming consoles, to reduce the risk of damage when power is restored.
4. Stay Informed During an Outage
Knowing the status of your outage saves you a lot of stress. Oncor offers several ways to track restoration:
- Report and track outages at stormcenter.oncor.com or via the MyOncor app
- Text alerts: text "REG" to 66267 to register, then "OUT" to report an outage
- Phone: 888-313-4747
During major events, Oncor has been transparent about realistic restoration windows — in the March 2025 storm, full restoration for the hardest-hit areas took several days. Planning around multi-day outages, rather than assuming power will return within hours, is the more realistic approach for North Texas.
If you have a household member who depends on electricity for a medical device, register for critical care status with Oncor in advance, though be aware this designation prioritizes your home during restoration but does not guarantee uninterrupted power, especially in severe weather. Have a backup plan for medical equipment regardless.
5. Don't Wait Until the Power's Out to Find Problems
A surprising number of "power outage" calls we get aren't actually utility-side outages at all — they're failures in a home's own electrical system that happen to coincide with stress on the grid (high AC load, an aging panel, a storm-damaged connection).
Here are some signs your home's electrical system may need attention before the next outage hits:
- Breakers that trip repeatedly under normal load
- A panel that's outdated, mislabeled, or shows signs of heat damage
- Flickering lights during storms or high-wind events, which can indicate a weak connection at the weatherhead or meter base
An Electrical Home Safety Inspection can catch these issues before they turn a routine grid event into a home-specific outage or, worse, a fire risk. For homes with Panels and Breakers showing their age, an upgrade now is far less disruptive than an emergency repair during a storm.
