Duke Energy Ohio and Kentucky Set New Electricity Demand Records February 7, 2007

Share RSS Feeds


Customers of Duke Energy Ohio and Kentucky set new records this week for winter electricity demand.

Duke Energy Ohio set a new winter peak of 3,680 megawatts at 8 p.m. Monday and then exceeded that record with a new peak of 3,716 at 8 a.m. yesterday. The old record was 3,609 megawatts set on Jan. 18, 2005.

Duke Energy Kentucky set a new winter peak of 728 megawatts at 8 p.m. Monday, breaking the old record of 701 megawatts set on Jan. 23, 2003. The Tuesday peak was 723 megawatts at 9 a.m., also breaking the old record.

“Growth in our service area continues to drive increased customer demand for electricity at peak periods,” said Sandra Meyer, president of Duke Energy Ohio and Kentucky.

Duke Energy is offering its customers the following “Top 10” tips for conserving energy and lowering their energy bills:

  1. If your windows allow cold air to leak into your home, the most cost-effective measure is to seal the entire window with a layer of plastic for the winter. New heat-shrinking films are airtight and easy to see through.
  2. Install the proper amount of insulation in exterior walls, roofs, ceilings and floors above cold spaces. If you currently have no insulation in one of these areas, installing insulation will cut your energy bills dramatically.
  3. If you have ductwork in the attic or garage, be sure it is covered with at least 6 inches of insulation. Seal the seams and joints in these ducts with a duct-sealing compound sold at hardware/home centers.
  4. Lower your thermostat temperature to the lowest temperature that is comfortable to your family. You may save as much as 3 percent on your energy bill for each degree you lower your thermostat.
  5. If your home has a crawl space with air vents in the walls, close the vents and seal with insulation from the inside during the winter.
  6. Never switch a heat pump to the “emergency heat” setting on the thermostat, unless the unit is malfunctioning. This switch will turn off your energy efficient heat pump. Using only your backup electric furnace without the heat pump could double your heating costs.
  7. Most fireplaces that are open to the living space will increase winter heating costs. Do not use a fireplace during periods of extreme cold. Keep your fireplace damper closed tightly when not in use. Consider installing doors over the fireplace opening to cut down on drafts and heat loss through the chimney.
  8. Consider adding a heat pump to any electric, gas or oil furnace to take advantage of a “dual fuel” heating system. The electric heat pump will heat a home for much less for most of the winter heating hours. The new heat pump will also serve as a new air conditioner and could save up to 50 percent on cooling costs, compared to a 15-year-old air conditioner.
  9. Energy-saving compact fluorescent light bulbs use up to 75 percent less energy than standard bulbs and last up to 10 times longer.
  10. A new ENERGY STAR®* refrigerator can use approximately one-third less energy than a 15-year-old model. Refrain from leaving the old refrigerator plugged in as a backup.

*ENERGY STAR® is owned by the U.S. Environmental Protection Agency, which is not affiliated with Duke Energy Corporation.
