About 300 Pepco customers in an area southeast of Lincoln Park in the District will lose power for an estimated four hours Friday starting at 11 p.m. while an underground line is repaired, the company announced late Friday.

The affected area is in the vicinity of 15th and C streets SE and South Carolina Avenue SE, the company stated. The work will repair electric cable in a manhole that Pepco crews drained and rebuilt Friday.

Pepco Region President Thomas Graham said in a news release that “Pepco regrets the inconvenience to our customers,” and that crews would finish “as quickly and safely as possible.”
