Dominion Resources (NYSE:D) announced Wednesday that its Virginia Power customers hit an all-time record for winter peak demand on Tuesday as "cold arctic air blasted the region." The electric utility supplied 19,730 megawatts between 7 a.m. and 8 a.m., surpassing a previous 18,079-MW winter record set in February 2007.

Dominion Resources also surpassed its previous record for 24-hour electricity use, beating out the 392,347 MW demand set on July 23, 2011, to clock in at 419,791 for Tuesday.

While utilities Duke Energy and PPL hit record highs in several states without significant power outages, Dominion's Virginia Power wasn't as lucky. It said 1.4% of its 2.4 million customers lost power at some point, but electricity has since been restored to all homes and businesses.
