WAKE COUNTY, N.C. (WTVD) -- As central North Carolina deals with record temperatures and dangerous heat, thousands in Wake County found themselves without electricity on Thursday.
According to Duke Energy, the outage happened around 2:15 p.m., affecting about 35,000 customers, mostly in the Cary and Morrisville areas.
A contracted helicopter crew performing vegetation management for the railroad damaged a transmission line, and a tree fell onto a power line along the tracks in Cary.
The helicopter was not contracted by Duke Energy, the company said.
Power outages in Cary affected residents as well as operations at several Town of Cary facilities, resulting in closures and modified operations.
"Suddenly we get a notice over text. That power would be out until 5, and it's well past five without air conditioning," said resident Liam Goff. "The kids are going nuts. The dog is going nuts. But you make do. They have homework on the computer, and there's no WiFi, right? Which is the way it operates now, which is totally fine in most cases. But when you're dependent on it, and it doesn't work, uh, it's a problem."
The Goffs had their power restored just before 8 p.m.
At High House Mini Mart and gas station, the loss of power forced employees to rely on manual calculations after electronic systems went offline. Without electricity, card readers, receipt printers and gas pumps stopped working.
"When I got here, all the employees come on. And really, what are we going to do? I was like, back to pen and paper," said Lila Jabber of High House Mini Mart. Drivers attempting to buy fuel were turned away as the outage prevented pumps from operating.
At Downtown Cary Park, the 7 p.m. Zumba class was canceled, and Guest Services was closed.
The Cary Senior Center, Herbert C. Young Community Center, Bond Park Community Center, and Page-Walker Arts & History Center were closed, and all evening programs at those facilities were canceled. The Bond Park Boathouse is also closed.
At the Cary Arts Center, all evening classes, open studios, and rentals were canceled. The 7 p.m. screening of "Horsegirls" at The Cary Theater was canceled, and ticket holders were notified.
Duke Energy is continuing to investigate the cause. Duke Energy spokesperson Jeff Brooks said the estimated time of restoration was 9 p.m. Power was fully restored late Thursday evening.
"We're working hard to complete the repair to the damaged equipment and get everyone restored as safely and quickly as possible," Brooks told ABC11.
Brooks said Duke Energy was working to switch customers to other lines to restore service more quickly.
The Cary outage was not the first this week. Multiple outages were documented in the region, including near downtown Raleigh on Tuesday and several outages in north Raleigh on Wednesday.
Duke Energy said nearly 46,000 customers have experienced power outages so far this week.
"We've certainly seen demand for electricity increase. It's been very hot, and everybody wants to stay cool. Obviously, so that does mean an increase in usage. Fortunately, we've been able to meet that demand reliably," Brooks said.
Brooks said fallen trees, combined with hot and dry conditions, have been a major factor in the outages.
"When you have sort of extended drought or high temperatures, it can affect trees that maybe are either weak or diseased," Brooks said.
He added that trees can damage power infrastructure even when they are not close to utility lines.
"We trim trees year-round to reduce outages on our system, of course, but these trees can be 70-80 feet tall, so they can be across the street, well away from our lines, and when they come down, they can still take down a line," Brooks said.
Brooks said Duke Energy has been making upgrades to the electric grid throughout the summer, including self-healing technology that helped some customers regain service within an hour.
