A power outage from an equipment malfunction kept residents of the Mount Vernon Campus in the dark for most of Sunday until Pepco restored power in the late afternoon.

The electricity failure, which affected the Mount Vernon Campus and the surrounding Foxhall neighborhood, left many residents without air conditioning and food due to the closure of Ames Dining Hall.

“It’s been really disruptive to all of us,” said Mount Vernon resident Ariel Pratt, a freshman. “We can’t use the Internet. We can’t do laundry, can’t do any of our normal Sunday stuff.”

Residents said some back-up generators were activated at the campus, but they only fed power to the GWorld entrance pad.

This is the second time in eight days that power went out at Mount Vernon. Last Saturday, a fallen tree knocked out electricity.
