CHARLOTTE, N.C. — Duke Energy customers in the Carolinas set an all-time record for power usage Wednesday morning.

Between 7 and 8 a.m., Duke customers used 17,570 megawatts of energy. That broke the record set Jan. 11, 2010, at 17,282 megawatts.

In Raleigh, Wednesday saw a low of 16 degrees and high of 37 degrees – about 17 degrees below normal. So far, it's been the coldest December on record at Raleigh-Durham International Airport.

"During a similar cold snap last year, the average residential customer saw a 30 percent increase in his or her power bill. We could see a similar trend this season," Gianna Manes, Duke Energy's chief customer officer, said in a statement. "We often forget that when the temperatures drop, our heating systems work harder and longer to maintain the comfort level in our homes."

About half of a household's energy use is consumed in heating and cooling, according to Duke Energy.
