The Tennessee Valley Authority said Wednesday morning's peak power demand was the second-highest for November. It's only the third time the authority has been above 26,000 megawatts in November.
Michelle Tolomeo just moved to Huntsville from California six months ago. The cold weather caught her a bit off guard.
"22 degrees this morning was a little bit of a shock. I thought yesterday at 27 degrees was cold. Today was really cold," said Tolomeo.
She said she's already turned on her heat.
"It's set about 69 right now so we're just tryna figure it out," said Tolomeo.
The Tennessee Valley Authority said you should keep your thermostat at 68 degrees, or whatever's key to you, but pick a temp and leave it there.
"So you're not heating your house up and then cooling it down and then heating it up. Save a little money," said Austin Aberle.
While helping people saving money on their bill is something TVA strives to do, it is also in the business of ensuring its systems don't get overloaded. A spokesperson said if that were to happen, it would bring on additional generators or purchase power from sister utilities in the region.
For now, customers told WAAY 31 they're going to keep their thermostats where they're at unless it gets colder.
"Well, more when I need a sweater," said William Kerr.
TVA said it has an on-site meteorologist that closely monitors the weather so it can be sure there is enough power to supply to all of its customers. For every one degree you drop your temperature, you can see savings up to three percent.
