Crews committed around the clock until all customers are restored

Washington , D.C. - Another series of thunderstorms tore through the nation's capital early this afternoon, causing more damage to the electric system and another wave of power outages. Crews from five states and the District of Columbia, who already were restoring service following Sunday's violent storm, wrapped this new series of outages into the effort. Crews had restored service to the vast majority of customers from Sunday's storm before this latest series of storms hit. Earlier today, the number of Pepco customers out of service had been reduced from a peak of 301,000 to about 6,000. Based on preliminary data, this new wave of storms piled an estimated 15,000 additional Pepco customers onto the list of those affected by the severe weather. Pepco is responding.

"The large number of crews already in our service territory allows us to address these new outages quickly and keep focused on those who lost power earlier in the week," said Thomas Graham, Pepco Region President.

More than 180 crew members from the company and more than 450 crew members from other utilities and contractors have been engaged in this effort around the clock.

Graham is expected to meet with members of the media at 10 a.m. tomorrow, Friday, July 30. The location of the news conference is the Pepco Restoration Staging Area at the Montgomery County Fairground.

Calling 1-877-737-2662 is the best method for customers to continue to receive estimated times of restoration.

Pepco continues to encourage all customers to call 1-877-737-2662 to report an outage and/or a down electric wire. Until power is restored, here are some tips to keep you safe, protect your home and belongings:

Protecting Your Home and Belongings if Your Power is Out:

· Turn off all appliances, including your furnace, air conditioner, water heater, and water pump. That way, you can avoid a circuit overload and another outage that may result when power is restored to all appliances at once.

· Leave on one lamp so you will know that the power has been restored.

· When using a generator, always follow the manufacturer's instructions.

· Locate your generator in a well-ventilated area. Never run it inside, even in your garage. Gasoline powered generators produce carbon monoxide and the fumes can be deadly. Store gasoline or other flammable liquids outside of living areas in properly marked approved containers.

· They should also not be stored in a garage if a fuel-burning appliance is located there.
