Kilowatchers Programs Activated
Fourth Time This Week

For Immediate Release
August 10, 2001

Pepco and other PJM power pool utilities today advised that it may be necessary to initiate further operational procedures to maintain the reliability of the regional electric grid during the sixth day of an intense heat wave.

Pepco greatly appreciates the public`s assistance in conserving electricity and requests that conservation measures continue today, especially from 3-7 p.m., health permitting. Steps that can be taken include:

• Close curtains and blinds to keep out the sun and retain cooler air inside their homes and businesses;
• Postpone using major heat-producing appliances like electric stoves and clothes dryers until the cooler evening hours;
• Set air conditioning thermostats higher than usual, and;
• Turn off non-essential lights, appliances and equipment.

PJM companies serving 22 million people in the mid-Atlantic region request this action to avoid implementing a voltage reduction today to preserve the integrity of the power grid. A voltage reduction lowers demand because equipment and appliances use less power to function. The reduced voltage should not be noticeable to customers.

Pepco has again implemented its Kilowatchers programs today, from noon to 6 p.m., to help reduce demand. Under Kilowatchers, 162,000 residential customers volunteer to allow Pepco to cycle their air conditioners off and on periodically on weekday afternoons. More than 300 commercial and governmental customers in Pepco`s Curtailable Load Program have agreed to reduce their demand.

PJM regional power pool, of which Pepco is a member, serves all or parts of Pennsylvania, New Jersey, Delaware, Maryland, Virginia and the District of Columbia.
