The Tennessee Valley Authority on Wednesday said it takes “full responsibility” for the impact of the first-ever mandatory power outages during the cold weather on Friday and Saturday last week, and it is reviewing what happened.

“We at TVA take full responsibility for the impact we had on our customers,” the electrical provider said in a press release posted on its website. “We never want to impact anyone’s energy at any time. This is not the way we want to serve our communities and customers.

“We are conducting a thorough review of what occurred and why. We are committed to sharing these lessons learned and—more importantly—the corrective actions we take in the weeks ahead to ensure we are prepared to manage significant events in the future.”

Half of power outages this year caused by falling trees, tree limbs

Half of the power outages in Oak Ridge this year have been caused by falling trees and tree limbs, Electric Director Ardo Ba told City Council on Tuesday.

Since January, vegetation has accounted for about 50 percent of power outages, Ba said.

Animals such as squirrels and snakes have caused about 13 percent of the power outages in the past six to seven months, and equipment failures, traffic crashes, and other causes have accounted for roughly 37 percent of the outages, Ba said.

Ba provided some details about significant power outages this year. The largest outage occurred on July 8 on Tuskegee Drive near a city fire station, when a transmission line switch caught fire. More than 8,400 people power.

The next largest outage was caused by a tree falling on a transmission line on Wiltshire Drive on May 27. The 150-foot tree that fell on the transmission line had been well outside the right-of-way, Ba said. That line provided a main feed to two substations, and more than 7,200 customers lost power when the tree fell on the transmission line.
