Much of the nation experienced an extreme cold snap over the recent holidays, and Tennessee was no exception with temperatures dipping to nearly zero degrees in Oak Ridge. Despite the bitter weather, preparations and recent upgrades helped prevent infrastructure failures during that time.

Many employees with EM cleanup contractor UCOR reported to work over the holidays to ensure issues were resolved at several essential facilities. (EM stands for environmental management.)

At the Environmental Management Waste Management Facility, advanced planning and preparation protected critical water management systems during the deep freeze over the nearly weeklong cold snap, including a 6.5-hour unplanned power outage.

The average temperatures in 2022 were above the normal temperatures in East Tennessee, but there were record cold temperatures reported on Christmas Eve, the National Weather Service said.

The number of cold hours around Christmas in late December might have seemed long, but it was not a record-breaker, the NWS said.

“The arctic front that ushered in this outbreak of cold weather moved through during the early morning hours on December 23,” the NWS said. Between then and the end of the cold streak, several locations recorded more than 100 consecutive hours at or below freezing (32 degrees Fahrenheit). Wise, a city in southwest Virginia north of Tennessee’s Tri-Cities, reported 107 hours below freezing, the NWS said. That’s equivalent to about 4.5 days. Oak Ridge was below freezing for 106 hours and Knoxville for 104 hours, both also close to 4.5 days.

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.”

Updated: TVA ends rolling blackouts

Note: This story was last updated at 12 p.m.

Mandatory rolling power blackouts continued in Oak Ridge and across the region Saturday morning. The City of Oak Ridge announced at about 11:40 a.m. Saturday that the power outages had been terminated.

Here is the previous story:

The blackouts will affect 10 percent of customers at a time, and power outages will last about 30 minutes, the City of Oak Ridge said in a press release. That’s a larger percentage of customers who will be affected by the Saturday outages than the ones on Friday, when about 2 percent of Oak Ridge customers were affected.

The Tennessee Valley Authority, which provides power to the City of Oak Ridge, said the blackouts are necessary because of the extreme weather conditions, according to the press release. The power demand is high as temperatures have dropped into the single digits in what has been called a “once-in-a-generation” storm.

TVA said the power demand is among its highest in its nearly 90-year history. Typical power demands for December are around 24,000 megawatts. On Friday, power demands surpassed 33,000 megawatts, TVA said.

Some side streets were still snow covered at about 10 p.m. Sunday, but heavily traveled roads and main roads such as South Illinois Avenue were mostly clear except for some slush. That raised the possibility that some surfaces might freeze overnight with the low forecast around 26 degrees Fahrenheit.

There is a 40% chance of snow in the Oak Ridge area before 2 a.m. Monday, according to the National Weather Service in Morristown.
