Delmarva Power Sets Record Winter Peak Power Demand

SALISBURY, Md. - Delmarva Power set an unofficial record winter peak demand today as customers pushed up their thermostats to deal with the frigid temperatures gripping the Delmarva Peninsula.

Customers demanded 3,575 megawatts of electricity at 8:00 a.m., surpassing the old winter mark of 3,486 megawatts recorded on January 28, 2005. (One megawatt of electricity is enough to power 800 to 1,000 homes). A final, official tabulation could result in a slight adjustment in the amount of power consumed by customers.

Delmarva Power's all-time record peak demand is 4,288 megawatts set on August 3, 2006.

Delmarva Power encourages its customers to use energy efficiently to keep their homes and businesses warm. Heating costs can account for 25 percent to 50 percent of a home's total energy expense.


Delmarva Power, a public utility owned by Pepco Holdings, Inc. (NYSE: POM), provides safe and reliable energy to more than 500,000 electric delivery customers in Delaware, Maryland and Virginia and over 118,000 natural gas delivery customers in northern Delaware .
