With temperatures falling to an average of only 7 degrees this morning across the Tennessee Valley, TVA set a new winter record for the highest electricity demand in its 7-state region.

TVA customers used 33,345 megawatts of electricity early today during the frigid cold — the third highest peak for TVA and the highest ever during the winter.

TVA said it has lifted its appeal for conservation as temperatures have warmed today. TVA met the peak demand by relying upon a diversified mix of power generation, including 29 percent of its power from coal-fired plants, 21 percent from nuclear plants, 24 percent from natural gas plants, 12 percent from hydroelectric dams, 2 percent from wind farms and 12 percent from power market purchases.

"For the second time this month, TVA sincerely thanks everyone across the seven-state TVA service area for conserving energy and helping us provide a safe, reliable flow of electricity during this latest cold wave," said Tim Ponseti, vice president of TVA Transmission Operations and Power Supply. "The effort made by our employees and customers during this round of bitterly cold weather exemplifies the teamwork and skill required to provide low-cost, reliable power.”

With more cold weather on the way next week, TVA is continuing its internal Conservative Operations Alert, delaying non-emergency maintenance activities at its generation and transmission facilities to minimize risks to the power supply.

TVA’s all-time peak demand record remains 33,482 megawatts, set on Aug. 16, 2007, when temperatures averaged 102 degrees.
