TVA meets all-time record demand for electricity

Record high temperatures on Aug. 16 pushed consumer demand for electricity to an all-time high on the TVA system. Peak use reached a record 33,499 megawatts at 6 p.m. EDT, when temperatures across the 80,000-square-mile service region averaged 102 degrees.

The previous all-time system peak of 33,332 megawatts was met on Aug. 8, when the average temperature across the Valley was 98 degrees.

TVA set a total of 13 peak power demand records – more than one every three days – during the month.

The TVA service territory also recorded the highest average temperature in 55 years on Aug. 16, when the average Valley temperature reached 103.6 degrees at 4 p.m. EDT.

August was the hottest month ever recorded in Nashville, Knoxville, Chattanooga, Bristol, Huntsville, and Tupelo. Nashville came within one degree of an all-time record high on Aug. 16 when the temperature hit 106 degrees, and Chattanooga did the same on August 23 with a high temperature of 105 degrees. Temperatures in Nashville were 100 degrees or above on 15 days in August – more than the combined total in the last 15 years.

“Given the challenges we’ve faced over the past couple of weeks, our power system has held up amazingly well due to the hard work of our employees,” says TVA President & Chief Executive Officer Tom Kilgore.

TVA’s entire generating fleet, transmission system, power-purchase arrangements, and distributors of TVA power made strong contributions in meeting the record demand. All 59 of TVA’s fossil units, all six nuclear units, all four pumped-storage units, 90 of 109 hydro units, and all but one of TVA’s 83 combustion-turbine units were available for service during the peaks, as were most of TVA’s renewable energy units.
