Pepco Expects Mutual Assistance to Help Restore The Remaining Customers

WASHINGTON - As of 10:00 this evening, Pepco has restored power to more than 36,000 customers since the midday high winds passed through the Washington Metropolitan Region bringing tree limbs into contact with power lines and causing outages throughout the service territory. At the height of the storm, outages on the system peaked at approximately 47,000. Currently approximately 10,300 customers remain without power.

Throughout the day, Pepco mobilized more than 650 personnel, working 16 hour shifts to restore power to customers. That number includes company crew personnel and contractors actively assessing damage and restoring power, Call Center representatives staffing phone lines, and other supporting staff. Crews will continue to work through the night and expect 230 additional personnel from mutual assistance crews tomorrow morning.

"I'm proud of the work our crews have been able to accomplish today," said Thomas Graham, President Pepco Region. "Additional outside crews will work on the Pepco electric system to help restore the vast majority of customers by tomorrow."

To report Power Outages and Downed Wires Call 1-877-737-2662.

Please stay away from downed wires and report them immediately.

If you are calling to report a power outage, please call 1-877-Pepco-62 (1-877-737-2662) and press one. If you are reporting a life threatening emergency situation such as a burning downed wire please call 1-877-Pepco-62 (1-877-737-2662) and press two.

The option for reporting an actual life threatening emergency should NOT be used to report an outage, as it will prevent customers with actual emergencies from getting through.

Customers also are asked to call Pepco to report outages - even if their neighbors already may have called. Pepco's automated outage reporting system is the most effective way to report an outage because it immediately feeds information into computers that rapidly identify problem areas and dispatch repair crews, so that power can be restored as quickly as possible.

Power Restoration Process - How Pepco Restores Power

Once the storm subsides, crews will survey the electric system to assess the damage. As with plowing roads, it is not possible to clear side streets before the main roads are cleared. To that end, in the event our system is damaged by severe weather, Pepco repairs equipment that will restore the largest numbers of customers first. Generally, the power restoration sequence is as follows:

· Downed live wires or potentially life-threatening situations and public health and safety facilities without power

• Transmission lines serving thousands of customers
• Substation equipment
• Main distribution lines serving large numbers of customers
• Secondary lines serving neighborhoods
• Service lines to individual homes and businesses

Pepco urges customers to stay safe and be prepared. Here are some additional tips:

• Assemble an emergency storm kit. Include a battery-powered radio or television, flashlight, first-aid kit, battery-powered or windup clock, extra batteries, non-perishable food, manual can opener, bottled water, any necessary medications and a list of emergency phone numbers.
• Maintain a supply of extra blankets.
• Ensure that all household members have a warm coat, gloves, hat and water-resistant boots.
• Make sure your home has a telephone with a cord or cell phone to use as a backup. Cordless telephones require electricity to operate, and won't work if there is an outage.
• Identify a place for emergency shelter in case of an extended outage. It is important that customers with special needs or their caregivers take responsibility to make arrangements ahead of time to prepare for potentially long-lasting service interruptions.
