Dominion Virginia Power has met a “record winter peak demand” for electricity from its 2.4 million customers after cold arctic air spread across the region on Tuesday, according to Dom.com.
According to the website, Dominion supplied 19,730 megawatts of electricity between 7 a.m. and 8 a.m. on Tuesday, January 7, 2014. That is an increase of about 1,650 megawatts over the previous winter peak demand record of 18,079 megawatts, which was set between the same hours on Feb. 6, 2007, Dominion says.
The all-time peak demand record is a summertime mark of 20,061 megawatts set on July 22, 2011.
One megawatt supplies enough electricity at peak for 250 homes.
Dominion also set an all-time record for energy usage over a 24-hour period. Total energy usage for Tuesday was 419,791 megawatts. The old record was 392,347 megawatt hours set on July 23, 2011.
