Updated: TVA ends rolling blackouts

Posted at 7:32 am December 24, 2022

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.

ORNL analysis predicts extreme weather losses could double by 2050

U.S. economic losses from extreme weather could at least double by 2050, according to an Oak Ridge National Laboratory analysis published this month in the online edition of the journal Global Environmental Change.

“A side effect of America’s growth has been the tendency to put more people, infrastructure and assets in harm’s way, and when a storm comes through, that increased exposure drives up economic losses,” said author Benjamin Preston, deputy director of ORNL’s Climate Change Science Institute, who studied historical data from more than 3,000 U.S. counties and used predictive modeling in the assessment. Preston works in impacts, adaptation, and vulnerability science, a field devoted to analyzing the effects of climate change on people, governments and industries. [Read more…]

UT study predicts extreme climate in eastern United States

Posted at 6:29 pm December 17, 2012
By University of Tennessee 2 Comments

From extreme drought to super storms, many wonder what the future holds for the climate of the eastern United States. A study conducted by researchers at the University of Tennessee in Knoxville does away with the guessing.

Results show the region will be hotter and wetter.

Joshua Fu, a civil and environmental engineering professor, and Yang Gao, a graduate research assistant, developed precise scales of cities that act as a climate crystal ball, seeing high-resolution climate changes almost 50 years into the future.

The study found that heat waves will become more severe in most regions of the eastern United States and that both the Northeast and Southeast will see a drastic increase in precipitation.
