TVA has near-record peak demand during cold streak

The Tennessee Valley Authority has met a record-breaking winter demand for electricity this morning by providing an estimated 33,345 MW, the agency announced.

Precipitated in large part by average temperatures of 7 degrees across TVA‘s consumer base, the demand was the agency’s highest since the summer of 2007 and third-highest in its history.

TVA said 12% of the power was produced by hydropower projects, with coal-fired plants adding 29%, nuclear plants (21%), natural gas (24%), wind farms (2%) and power market purchase (12%).

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,” said Tim Ponseti, vice president of TVA Transmission Operations and Power Supply.

The announcement comes just a day after TVA asked its power distributers and their nine million customers to conserve energy during this most recent cold spell, which follows one January 7 during which there was 32,500 MW of demand.

“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,” Ponseti said.

TVA data shows its all-time peak demand record is 33,482 MW, set on Aug. 16, 2007, when temperatures averaged 102 degrees.
HydroWorld.com reported in October that TVA had broken its 40-year old record for electricity generated in a fiscal year.
