Customers Should Continue to Be Prepared

WASHINGTON - Pepco is preparing for another dose of winter weather, bringing with it the potential for significant snow accumulation as well as a wintry mix in some areas. Heavy wet snow and strong winds could bring tree limbs onto wires, resulting in power outages. Outages also can occur due to drivers skidding into utility poles located along icy and snow-covered roads.

Extra crews and customer service personnel are prepared to work throughout the storm. When road conditions become treacherous due to ice or heavy snow, Pepco will equip vehicles with chains to safely respond to outage calls. Pepco will coordinate its power restoration efforts with emergency management personnel and local government officials.

If Power Goes Out

Pepco strongly urges everyone to stay away from downed lines and report them immediately by calling

1-877-737-2662 .

Customers also are asked to call Pepco at 1-877-Pepco-62 (1-877-737-2662) 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.
