The Tennessee Valley Authority said it delivered a record amount of power on Friday and set a winter record for peak power demand.
TVA supplied 740 gigawatt-hours, or 740 million kilowatt-hours, during a 24-hour period on Friday, December 23. That’s more energy supplied than at any other time in its 89-year history, TVA said.
The cold also produced a winter record for peak power demand of 33,425 megawatts at 7 p.m. Central time, when the region-wide average temperature was 9 degrees, TVA said.
“Record-setting temperatures across the region continue to put intense pressure on the power system,” TVA said in a press release. “The Tennessee Valley Authority and local power companies (worked) around the clock in difficult conditions to meet this extreme demand.”
On Saturday morning, December 24, TVA directed local power companies to implement planned, short-duration, intermittent power interruptions to maintain system reliably, the press release said.
“This action is similar to steps that TVA and local power companies took on Friday, December 23, to help ensure power system reliability,” the press release said. “This measure is expected to be temporary until the highest peak power demands have been met. The strong partnership between TVA, local power companies, and industrial customers, as well as the individual contributions of residents to conserve energy, continues to make a difference.”
“We appreciate the work of so many local power companies, businesses, and residents to assist TVA in managing the impacts of this extraordinary weather event,” said Don Moul, TVA’s chief operating officer. “We remain committed to working together to manage the demands of this extraordinary weather and still make the holidays safe and warm.”
