This week's cold weather has led to new records in power usage in the Carolinas.
South Carolina Electric & Gas says customers used 101,118 megawatt-hours of electricity Tuesday as lows dipped into the single-digits and teens and highs failed to get above freezing across most of the state.
That broke the previous record for a full day's usage of 98,785 megawatt-hours, set on August 10th, 2007, when air conditioners – not heaters – were humming. On that date six and a half years ago, Columbia had a high of 107 degrees after most of the state had seen several days of highs over 100.
Meanwhile, Duke Energy says its customers set a winter peak demand record for a single hour Tuesday morning.
Duke Energy Progress, with customers east of Columbia and in the Pee Dee, says 14,190 megawatt-hours of electricity were used during the hour ending at 8 a.m., surpassing the previous winter record of 13,884 set on January 11th, 2010.
And Duke Energy Carolinas, with customers in the northern Midlands, says 20,246 megawatt-hours were used – also from 7 to 8 a.m. – breaking the previous winter peak demand of 18,985 set on December 15th, 2010.
