More than 548,000 US customers without power as winter storm freezes much of the US

A severe winter storm that brought heavy snow, sleet and freezing rain left more than 548,000 homes and businesses without power across a swath of the U.S., from the Ohio Valley and mid-South to New England.

The hardest-hit utilities included Nashville Electric Service (NES) in Tennessee, where 143,016 of 463,455 customers were without power, and Entergy, with more than 121,600 of 3.05 million U.S. customers affected, according to PowerOutage.us.

"NES teams continue to work to make repairs and restore power to customers after freezing rain and ice impacted the NES service territory and have restored power to 90,000 customers," Nashville Electric Service said in a post on X late on Monday.

The storm was set to become the costliest severe weather event since the Los Angeles-area wildfires in early 2025, with preliminary damage and economic losses estimated at $105 billion to $115 billion, AccuWeather said.

"Entergy Mississippi began restoring power to customers as safely and quickly as possible after the winter storm passed. Our crews, along with mutual assistance contractors, will continue working around the clock until all power is restored," Entergy said in a release on Monday.
