Heavy Rain and High Winds Deliver Likely Power Outages Tomorrow

WASHINGTON - Today Pepco announced that it is closely watching the development of another major weather event that could impact the Washington Metropolitan Region. Strong surface winds greater than 35 miles per hour with gusts in excess of 50 miles per hour accompanied by heavy rain are forecasted to reach the Pepco Region tomorrow afternoon. With the combination of wind and rain, trees already weakened by previous storms this winter season are especially susceptible to fall onto power lines and equipment causing power outages. Pepco is prepared in the event strong winds once again impact our region and tree limbs and branches fall on utility wires causing power outages.

"Pepco employees are prepared to work in their secondary roles during significant weather events, with additional linemen crews and contractors on stand by to support the restoration process," said Thomas Graham, President, Pepco Region. "We will continue to monitor this wind event. Our crews will respond to any challenges these storms present."

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

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.

Please stay away from downed wires and report them immediately. 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.
