Pepco Crews are Repairing Additional Underground Cable Problems

Cooling Center to Remain Open Until Power Restored

WASHINGTON - Pepco crews have identified the location of a second underground cable failure linked to yesterday's outage affecting more than 1,500 residential and commercial customers north of Union Station near North Capitol Street.

Pepco expects to restore power to affected customers by midnight. The outage was caused by failures in underground cables that are part of a "network" that provides power to the affected area. Crews worked as quickly and safely as possible last night to make initial repairs. Today, Pepco crews located and began repairs to the second cable failure.

Pepco representatives continue to contact residential and commercial customers in the affected area to give updates.

A cooling center at the Walker Jones Education Campus, 1125 New Jersey Ave., N.W. will remain open until all power is restored. Pepco has coordinated with the District of Columbia government throughout this event.

Pepco advises any customers who have special needs, such as special medical equipment, to activate their emergency plans. All customers should take appropriate measures to deal with the extreme heat.

Pepco is prepared to respond to any additional outages that may be caused by severe weather later today.

Customers are encouraged to call 1-877-737-2662 to report outages.

Here are some tips to help prepare for outages:

• 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.
• Make sure there is a home 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.
