Pepco Reminds Customers High Temperatures Cause Outages

Washington, D.C.- Pepco and the other utilities in the mid-Atlantic region request that the public conserve electricity Tuesday, August 1, 2006 because of the expected intense heat and humidity and very high demand for power.

While adequate supplies of power are available, PJM Interconnection, the electricity grid operator for the region, is taking precautions to ensure the reliability of the transmission system during this time of heavy usage of the grid. Electric customers in the region are asked to conserve power, if health permits, especially between 3 p.m. and 7 p.m.

Pepco offers the following conservation tips:

  • Close curtains and blinds to keep out the sun and retain cooler air inside your home, apartment or business.
  • Postpone using major heat-producing appliances like electric stoves, dishwashers and clothes dryers until the evening hours; if possible, delay using them until the extreme heat subsides.
  • Set your air-conditioner thermostat higher than usual if health permits.
  • Turn off non-essential lights, appliances and equipment. This is especially important for business customers of all types.

Pepco will continue to monitor conditions. The PJM-East pool serves customers in all or parts of Pennsylvania, New Jersey, Delaware, Maryland, Virginia and the District of Columbia.

Further measures by PJM could be avoided if both residential and commercial customers observe conservation measures in their electricity use during this period of extreme heat and humidity. There is the potential for record-setting electric usage by Pepco depending upon customer demand. The peak demand for Pepco was set July 27, 2005 when usage hit 6,725 megawatts.


Pepco, a subsidiary of Pepco Holdings, Inc. (NYSE: POM), delivers safe, reliable and affordable electric service to more than 745,000 customers in Maryland and the District of Columbia.
