The utility said it notched a new record for winter peak demand between 7 and 8 a.m., when estimated preliminary peak demand for electricity averaged approximately 16,859 megawatts, exceeding the company's previous winter record set Dec. 14, 2010 of 15,806 MW by more than 1,000 MW.
The peak corresponded directly with the lowest temperatures of the week, with morning temperatures in many parts of the state in the single digits. In Cobb County, temperatures as low as 4 degrees were recorded, a record low for Jan. 7.
To ensure adequate power supply for all customers during the extended period of record-breaking low temperatures, the company brought additional generation online prior to the arrival of the frigid weather. The company also worked "around the clock to carefully monitor power loads on circuits and had crews and engineering teams on call to respond to any potential issues or service interruptions."
"The ability to quickly coordinate and respond to potential threats across our network is part of our great strength as a company," said John Pemberton, senior vice president and senior production officer for Georgia Power.
"Weather such as this reinforces the need for us to continue to invest in our infrastructure including multiple sources of generation and advanced 'smart grid' technologies in order to deliver safe and reliable power to customers."
Georgia Power serves 2.4 million customers in 155 of the state's 159 counties.
Georgia Power is the largest subsidiary of Southern Company (NYSE: SO), one of the nation's largest generators of electricity.
