Metropolitan Area under Winter Weather Advisory

Wet Snow Can Bring Tree Limbs into Contact with Power Lines Causing Outages

Customers Should Be Prepared

WASHINGTON - Pepco is prepared for the latest wintry mix of snow and ice that will hit the Washington Metropolitan Area.

The National Weather Service has issued winter weather advisory for the Washington metropolitan area. Predictions call for a wintry mix of rain and sleet changing over to snow with accumulations of 2 to 5 inches of snow and sleet. The heaviest snowfall is predicted to occur between 1 a.m. and 4 a.m., Tuesday morning. Heavy wet snow could bring tree limbs onto wires, resulting in power outages. Pepco has scheduled crews and local contractors to work around-the-clock, and has reached out to additional contractors for mutual assistance. Pepco's customer service personnel are also prepared to work throughout the storm. Pepco will coordinate its power restoration efforts with emergency management personnel in each of its three jurisdictions. If Power Goes Out and to Report 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.

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.
