Severe Storms Leave Over 620,000 Without Electricity Across U.S.

More than 620,000 customers across the United States were without power as of late Sunday following severe storms, with up to 2% of customers in some areas experiencing outages, according to Oilprice.com, citing PowerOutage.com.

Residents across Pennsylvania, Michigan, New York, New Jersey, Maryland, Connecticut, Virginia, and Texas were without electricity on Sunday night, according to PowerOutage.com, which tracks live power outages across the United States.

Michigan and Pennsylvania recorded the highest shares of customers without power, at 2% and 1.7%, respectively, according to the outage tracker.

Pennsylvania’s PPL Electric Utilities said it had restored power to more than 130,000 customers since the storms began this weekend, but warned that “significant work remains as crews continue repairing extensive damage and rebuilding portions of the electric system.”

The utility described the event as one of the most significant and impactful storms in its history. Since Friday, it has identified more than 2,360 locations with damage, including downed wires, broken poles, and damaged equipment.

“Due to the extensive damage caused by this storm, restoration is expected to be a multi-day effort, with restoration work continuing through July 8, 2026” PPL said.

In Michigan, DTE Energy said it estimated that 85% to 90% of affected customers would have power restored by the end of Sunday, July 5.

In New York, Con Edison said early Monday that crews had restored power to more than 166,800 of the approximately 173,700 customers affected by extreme weather, ranging from record-breaking heat to severe thunderstorms with destructive wind gusts.

The storms followed an extreme heat wave that gripped much of the United States. Late last week, PJM Interconnection, the operator of the nation’s largest electric grid, issued a maximum generation alert, urging power producers to maximize electricity generation as electricity demand surged.
