Over 335,000 US customers without power after winter storm

Over 335,000 homes and businesses in central and the southern U.S. were without power on Monday, data from PowerOutage.us showed, after a winter storm brought snow, ice and freezing temperatures.

The U.S. is bracing for further disruptions as blizzard conditions persist in several states.

The storm is expected to move offshore late on Monday, but it will be replaced by Arctic air, lowering daytime temperatures significantly, the National Weather Service said.

Governors in several states, including Kansas, Kentucky, Arkansas, West Virginia and Virginia, have declared states of emergency.

The Electric Reliability Council of Texas (ERCOT) on Sunday announced a weather watch from Jan. 6-10, citing anticipated cold weather across its region, which is expected to increase electrical demand and could reduce reserves.

However, grid operations are forecast to remain normal during the ERCOT weather watch.

Transmission organization PJM Interconnection issued a cold weather advisory for its Western Region for Jan. 8-12.

This advisory helps generation owners prepare their units for extreme weather and ensures reliable electricity supply during high demand periods.

Appalachian Power Company reported the highest number of affected customers, with 55,255 clients without power in Virgina and 46,836 clients in West Virgina.

CenterPoint Energy Indiana said 46,553 clients had reported power outages in Indiana.
