More than 847,000 homes and businesses remained without power late on Sunday after a severe winter storm pushed heavy snow, sleet and freezing rain across regions from the Ohio Valley and mid-South to New England. Some utilities were able to restore service during the day, decreasing the number of affected customers from more than 950,000 earlier.
The storm had a pronounced effect on several large distribution companies. Nashville Electric Service in Tennessee reported about 185,000 of its 463,455 customers were still without power. Entergy said more than 145,000 of its 3.05 million customers across the U.S. were without electricity, according to PowerOutage.us.
Describing the system-wide impact as "historic," U.S. President Donald Trump on Saturday approved federal emergency disaster declarations for a dozen states, mostly in the mid-South. Nashville Electric Service posted on X that, "NES lineworkers will continue overnight and we will not stop until power is back on for all customers."
Duke Energy warned that outages were expected to climb steadily throughout Sunday evening. The company noted North Carolina accounted for most of its outages, according to PowerOutage.us.
The highest outage totals by state were reported as follows:
| State | Outages |
|---|---|
| Tennessee | 258,004 |
| Mississippi | 157,573 |
| Louisiana | 123,156 |
| Texas | 65,003 |
| Kentucky | 48,942 |
| South Carolina | 47,587 |
| North Carolina | 36,289 |
| Georgia | 35,206 |
| Total Out | 847,102 |
Utilities continued to mobilize crews to restore service as conditions allowed. Where lines and infrastructure were damaged or iced, work proceeded overnight with the aim of returning power to affected customers as quickly as safety would permit. The federal emergency declarations cover a group of mostly mid-South states, enabling additional federal support for response and recovery operations.
As the event progressed, some utilities reported partial restorations during daytime hours, reducing the peak number of outages from more than 950,000 to the totals reported late on Sunday. Local conditions varied widely, with frozen precipitation and wind complicating travel and field restoration work in several areas.
Officials and utilities continued to monitor the situation and coordinate crews and resources. Outage maps and utility bulletins provided ongoing updates on the numbers of customers affected and restoration priorities.
