The Tennessee Valley Authority says they've been prepping all year for extreme cold

NASHVILLE, Tenn. (WTVF) — Following the debacle that was Christmas 2022, the Tennessee Valley Authority officials said they've been preparing all year for this extreme cold.

Late Sunday, the region will be kicked into the 20s, with single-digit lows early in the week. This will be the coldest air we've experienced since December 2022. That month, a winter storm wreaked havoc across the country and was the coldest system average temp since February 1996. In Tennessee, that meant TVA had its highest demand on the power grid, and the state experienced rolling blackouts.

"In 2023 out of the lessons learned from winter storm Elliott, we have completed a $123 million investment in winterizing all the equipment," said Scott Brooks, TVA spokesperson. "We basically winterized our equipment at our generating plants — focusing on the cold fleet and natural gas heat, which experienced the most issues in the cold temperatures."

TVA says they've been working nonstop to complete their more than 3,400 winter readiness activities, including enclosures around exposed equipment, Insulating exposed heated electrical cabling and modernizing their heat trace technology. Brooks said those fixes started directly after the cold snap in 2022.

Sensing lines at several coal and natural gas plants froze, essentially making those plants inoperable as demand for power rose. That's what triggered TVA to call for those blackouts, which the agency explained to Tennessee lawmakers in 2023.

"We didn't waste any time," Brooks said. "We looked at what went wrong. We got to work. We spent the last six months of '23 making those repairs. This was an unprecedented event all along the east coast. We looked for other utilities of how we can work together and create contracts to purchase energy."

TVA crews will be at generator sites, and Brooks said they would be hyperfocused during the weekend as the storm comes in Sunday into Monday.

How can I prepare for the winter storm?

That means knowing the signs of frostbite and hypothermia, bundling up and staying dry and having multiple ways to receive information about the weather.

You can sign up for alerts from your local NWS office, download the FEMA app and check the wireless emergency alert settings on your phone to get ready.
