KNOXVILLE—The Tennessee Valley Authority met a record-breaking winter demand for electricity Friday morning with an estimated 33,345 megawatts when the average temperature across the region hovered at 7 degrees.

This would be TVA’s highest demand for electricity since the summer of 2007 and third-highest in TVA history, a press release said. The previous winter record was 32,572 megawatts set on Jan. 16, 2009.

Meeting the record demand required the combined efforts of TVA’s employees and generating facilities, coordination with the Valley’s 155 local power companies and large industrial customers, and the cooperation of businesses and households to conserve, the press release said.

The release said TVA received 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. [Read more…]
