​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 Montgomery County.

Key Components and Benefits

• 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 November 2018 and will continue through May 2021. The work will affect traffic along several roads including Georgia Avenue, Linden Lane, Seminary Road, Hale Place, Fraser Avenue, Montgomery Street, and Brookville Road. Work will typically take place Monday through Friday, from 9 a.m. to 3:30 p.m. *
