Dominion Virginia Power Sets Record Peak Demand for Electricity

RICHMOND, Va., July 25, 2011 /PRNewswire/ -- Dominion Virginia Power set a new all-time record peak demand for electricity from its 2.4 million customers Friday afternoon, July 22, as a summer heat wave continues.

"While Dominion Virginia Power has adequate supplies of electricity and transmission capacity to meet anticipated customer demand, we encourage customers to use electricity prudently and to take measures that allow them to save money while remaining safe and comfortable," said Scot Hathaway, vice president-electric transmission.

Dominion Virginia Power, a subsidiary of Dominion (NYSE: D) supplied 20,061 megawatts of electricity between 3 p.m. and 4 p.m. Friday July 22.. The previous summer peak record of 19,688 megawatts was set on Aug. 8, 2007.  One megawatt supplies enough electricity for approximately 250 homes.

The company is urging all residents – especially the elderly and young children – to take precautions when going out in the heat and to limit their outdoor activities.  Customers with special needs – particularly elderly and ill persons without air conditioning who are most vulnerable to the effects of extreme temperatures and high humidity – should be checked on frequently.

To stay safe in this hot weather, Dominion urges everyone to:

• Avoid strenuous outdoor activity. If you must work outside, take frequent breaks and drink plenty of fluids. Do not wait until you are thirsty.
• Stay indoors in a cool place, especially during the afternoon when temperatures are highest.
• If you must go outdoors, wear lightweight, light-colored clothing. Try to wear natural products such as cotton and avoid synthetics.
• Be especially sensitive to pets, allowing them to stay inside when possible and keeping them hydrated with plenty of water.

The following energy conservation tips require little or no expense and could help lower electric bills while keeping homes comfortable:

• Postpone activities that require hot water – such as washing dishes or clothes – to early morning or late evening.  This will keep from adding more heat and humidity to the home.
• Avoid using your stove and oven if possible and consider using the microwave.
• If you are comfortable, raise your thermostat to 78 degrees in the summer.
• Turn off unnecessary lights during hot weather. They add to the heat in a house. Consider switching to cooler, energy-efficient CFL bulbs where light is needed.
• Use ceiling fans and portable floor fans to move the air around in the home. If the home does not have air conditioning, fans are essential for cooling. In homes with air conditioning, fans allow residents to raise the thermostat and save energy without affecting their comfort.
• Close drapes during the hottest times of the day to block heat from entering the home and to save energy.
• Make sure window air conditioners are sized correctly. Ones that are too small will run constantly, but they will not cool the room. Ones that are too large use more energy than necessary.
• Clean filters to window air-conditioning units and clean or replace filters to central air-conditioning systems. Clogged filters cause air conditioners to use more energy than necessary to keep a home cool.
• Clear attic vents. If the home has an attic fan, make sure it is functioning properly.
