The Tennessee Valley Authority said it hit a single-day record for electricity use as users cranked up their thermostats to keep warm this week.
The TVA said homes and businesses across its seven-state region used 703 gigawatt-hours of electricity on Tuesday, the most ever for a 24-hour, one-day period. TVA’s previous record was 701 gigawatt-hours on Jan. 8, 2010.
The single-day record came one day after TVA had its fourth highest “energy day” ever on Monday with 678 gigawatt-hours.
The Valley’s average temperature Tuesday never got above 21 degrees, and the average was just 4 degrees that morning when TVA’s power system experienced its second highest winter peak power demand in the public utility’s history, a 32,460-megawatt peak load on Tuesday.
TVA received 28 percent of its power from coal-fired plants, 21 percent from nuclear plants, 14 percent from combined cycle natural gas plants, 11 percent from hydroelectric dams, 10 percent from conventional gas turbines, 2 percent from wind farms and 13 percent from power market purchases.
With temperatures warming and system demand coming down, TVA lifted power supply and conservative operations alerts at noon on Wednesday. The alerts had been in effect since the weekend.
