Dallas, Texas — Energy providers across the southern United States are moving into high-alert mode as a potentially catastrophic winter storm threatens to deliver widespread ice, heavy snow, and prolonged Arctic cold across at least 35 states, putting regional power grids under intense strain heading into the weekend.
From Texas through the Carolinas, utilities say significant ice accumulation—in some areas exceeding half an inch—poses the greatest risk. Ice of that magnitude can snap tree limbs, bring down power lines, and trigger long-lasting outages, especially when paired with multiple days of subfreezing temperatures that slow repair efforts.
Meteorologists warn the storm could become one of the most impactful winter events the South has faced in years, with restoration timelines potentially complicated by dangerous cold in the Southern Plains and southern Appalachians.
Ice Accretion Raises Red Flags for Utilities
Utility officials emphasize that ice is more damaging than snow when it comes to power infrastructure. Even small differences in accumulation can drastically change outcomes.
Key concern:
Two inches of ice can add more than 2,200 pounds of weight across 300 feet of power line—roughly equivalent to a compact car hanging from the wires.
That kind of load can overwhelm poles, transformers, and transmission lines, especially in regions not designed for frequent ice storms.
Texas Utilities Mobilize Ahead of Freeze
In Texas, memories of the 2021 Great Texas Freeze loom large. That historic cold snap killed 246 people, caused billions of dollars in damage, and remains the costliest winter storm in U.S. history.
While forecasters say this storm may not match 2021 in duration or intensity, its overlap with heavy ice and snow has utilities taking no chances.
Oncor, which serves much of West, Central, and North Texas—including the Dallas–Fort Worth metroplex—confirmed it is pre-positioning critical equipment such as transformers, poles, and line hardware.
“Oncor has prepared for winter weather, and our field teams have decades of experience safely restoring power in freezing temperatures,” said company meteorologist Kaiti Blake.
The utility added that additional crews will be on standby throughout the weekend, ready to respond as conditions deteriorate.
A weather watch is already in effect for large portions of Texas as temperatures are expected to plunge rapidly once the Arctic air arrives.

Regional Power Providers Activate Storm Protocols
Utilities across multiple southern states are echoing similar preparations.
Entergy, which serves parts of Texas, Arkansas, Louisiana, and Mississippi, urged customers to fully charge electronic devices ahead of the storm and monitor updates through its Storm Center.
Oklahoma Gas and Electric said winter readiness steps were completed in the fall.
“All available units at OG&E’s power plants are operating and ready to support the grid during this cold snap and for the rest of the winter,” the company said Wednesday.
Carolinas Prepare for Ice and Staffing Challenges
In South Carolina, Santee Cooper, the state-owned electric and water utility serving the Lowcountry and Grand Strand, confirmed it is boosting staffing levels and completing freeze-protection checklists for equipment.
“Santee Cooper is monitoring the weather and preparing accordingly to help us be best positioned to keep the lights on for all of our customers across the state,” said Marty Watson, senior director of commercial and customer service.
Officials noted that prolonged cold following the storm could delay repairs, even if outages are initially limited.
Arctic Air Could Prolong Power Outages
Beyond ice and snow, days of Arctic air are expected to settle in behind the storm. In parts of the South, temperatures may remain below freezing for extended periods, creating challenges for both infrastructure and public safety.
Important risks include:
- Delayed power restoration due to unsafe working conditions
- Frozen equipment and access issues
- Increased demand on the grid as heating usage spikes
- Higher risk for vulnerable populations without power
Utilities stress that even well-prepared systems can struggle when ice damage and extreme cold overlap.
Officials Urge Public to Prepare Now
Energy providers are urging residents across the South to prepare in advance, especially in areas prone to ice.
Recommended steps include:
- Charging phones, power banks, and medical devices
- Having flashlights, batteries, and blankets ready
- Planning for possible multi-day outages
- Checking on elderly neighbors and those with medical needs
As the storm draws closer, utilities say conditions could change rapidly, and restoration timelines may depend heavily on ice severity and post-storm temperatures.
