COLUMBIA— Around 1 p.m. on Sunday, 160 homes in the Thornbrook subdivision experienced power outages.
Power was restored to most homes by 5 p.m., however, 40 homes were without power until 7 p.m., Connie Kacprowicz, Utility Services Specialist of Columbia Water and Light, said.
Thornbrook is a newer subdivision on the south side of Columbia where the electrical lines run underground. A line likely defaulted on Sunday because of the moisture in the ground, Kacprowicz said.
Underground electrical lines are generally more reliable because they avoid high winds, trees and ice, Kacprowicz said, but the repair time can take longer.
"It's harder to find where the problem is because you have to walk the line and find the source of the problem," Kacprowicz said.
Another outage in Columbia happened at 1 a.m. Monday near Bob Evans restaurant, at highways 63 and 70 Kacprowicz said. A circuit opened on an overhead power line because of equipment damage. Power was restored an hour later.
