Between 7 and 8 a.m., as systemwide temperatures dropped to teens and single digits in some areas, customers used 12,504 megawatt-hours (MWh) of electricity. That eclipsed the prior winter peak-demand record of 12,142 MWh, set on the morning of Feb. 6, 2007.

The all-time hourly peak-demand record for Progress Energy Carolinas customers was set Aug. 9, 2007, at 12,656 MWh, in triple-digit heat.

"We're working 24 hours a day to ensure that our customers have the power they need through this significant cold weather," said Lloyd Yates, CEO and president of Progress Energy Carolinas, which serves 1.5 million households and businesses in North Carolina and South Carolina. "We do not expect problems in meeting our customers' demand for electricity, but we encourage customers to learn more about how they can use energy wisely and efficiently - not only on frigid mornings but every day."

Progress Energy uses a mix of resources to meet the needs of customers in the region, including nuclear and fossil-fueled power plants, hydroelectric plants, biofuels, solar energy and energy efficiency. Progress Energy has a number of energy-efficiency programs for residential, commercial and industrial customers and demand-side management programs that help reduce electricity demand. The company's www.savethewatts.com Web site provides information on energy-saving opportunities for homeowners.

Household use of electricity, on average, has increased about 50 percent in the last three decades, due to growth in the average size of homes and increased use of electronics in daily life.

Progress Energy offers these tips for cold-weather energy conservation:

    --  Keep the thermostat on your heating system at the lowest comfortable
        setting. If you are going to be away for several days, turn the
        thermostat to a lower setting, but not to "Off." A sudden frigid snap
        could cause your pipes to freeze and burst.


    --  Check filters at least monthly and clean or change them as needed. Dirty
        filters can increase operating costs by 20 percent and can damage
        equipment.


    --  Caulk any space around windows and other places where air leaks to
        prevent cold drafts and heat escape.


    --  Use exhaust fans sparingly in winter. Heat and moisture from bathing and
        cooking contribute heat to your home. But don't use the oven to heat a
        room.


    --  If your home has a fireplace, be sure the damper fits tightly, and close
        it when the fireplace is not in use. Add a glass fireplace screen.


    --  Cover bare floors. Carpeting adds to comfort and heat retention,
        especially if there is little or no floor insulation.


    --  Use ceiling fans in winter to distribute heat around the room. Reverse
        the direction of the fan blades from that used for summer cooling.


    --  Use insulated or heavy curtains on windows facing the north side of the
        house. Keep curtains and shades closed at night and on cloudy days.


    --  For heat pump users, set the thermostat to a constant setting and leave
        it there, and make sure drapes and furniture are not blocking air
        registers or returns.


    --  Keep the oven, the refrigerator and other appliances clean. Clean
        equipment runs more efficiently.


    --  Use microwave ovens whenever possible. They use less than half the power
        of a conventional oven.


    --  Whenever possible, wash full loads in the dishwasher and clothes washing
        machine, rather than partial loads.


    --  Take short showers instead of tub baths and install a flow restrictor or
        energy-saving shower head.


    --  Look for EnergyGuide labels on most major home appliances.  The more
        efficient models save you money in the long run.
