Takoma to Sligo Underground Line

​Overview

At Pepco, our purpose is providing safe, reliable, and affordable energy for our customers. As part of our commitment to meet the growing demand for electric service and to enhance the capacity and reliability of our system, Pepco plans to upgrade the electric system infrastructure in the downtown Silver Spring area, with portions of work also occurring in Prince George's County and the District of Columbia.

Key Components and Benefits

  • Installing three new 69kV underground lines between the Takoma and Sligo substations, increasing the capacity of the Sligo substation
  • Replacing aging infrastructure that is near the end of its service life
  • Upgrading and installing new equipment at each substation, further improving reliability for customers

Project Timeline and Construction

Construction for this project will begin near Sligo substation in September 2017 and will continue through December 2022. The work will affect traffic along several roads including Fenton Street, Eastern Avenue, and New Hampshire Avenue. Work will typically take place Monday through Friday, from 9 a.m. to 3 p.m.

As a result of construction, businesses and residents may experience:

  • Road closures
  • Detours
  • Decreased accessibility to sidewalks
  • Construction-related noise

Areas of construction include:

  • Colesville Rd. (between Fenton St. & Spring St.)
