Current Reliability Projects

At Pepco, we care about the communities we serve, and we take seriously our commitment to deliver clean, safe, reliable, and affordable energy for our customers and communities. Every day, work is performed as part of our strategic effort to modernize and strengthen the local energy grid to better serve our customers. This effort includes dozens of targeted projects to modernize the energy grid and install new, state-of-the-art equipment in communities across the District of Columbia and Maryland. These upgrades continue to improve reliability for our customers by reducing the frequency and duration of outages.

Much of the work we do is focused on hardening our local infrastructure against more damaging winds and extreme storms. Across our service area, we are continuing to see the impacts of more frequent and more severe weather driven by climate change. We are continually analyzing the local energy grid to identify critical infrastructure projects to help the communities we serve become more resilient to the impacts of storms and hurricanes.

Comprehensive Feeder Program

As part of the Comprehensive Feeder Program, we are upgrading underperforming feeders across the city by replacing both primary and secondary overhead lines in designated areas and placing new overhead power lines on new poles. This work also includes transferring third-party attachments, such as cable, fiber and District Department of Transportation lines, onto the new poles. Once completed, all old poles will be removed.

DC PLUG (District of Columbia Powerline Undergrounding Initiative)

The DC PLUG initiative is a multi-year program focused on the underground placement of the most vulnerable distribution power lines. In the face of increasingly severe storms, the DC PLUG initiative is expected to improve resiliency and reliability. Click here for more information.

Downtown Distribution Resupply

We are installing a new distribution conduit system in the northwest quadrant of the downtown area of the District of Columbia. This work involves installing new distribution lines to connect our F Street and L Street substations, which will support and facilitate the rebuilding of both substations and increase the energy capacity downtown. This project has five separate phases of construction:

  • Phase 1: K Street, from 16th to 19th Streets – completed
  • Phase 2: L Street, from 16th to 19th Streets – work is underway and expected to be completed by end of 2021
  • Phase 3: 19th Street, from L to F Streets – scheduled to begin February 2022 and be completed by June 2022
  • Phase 4: 18th Street, from K to E Streets – scheduled to begin February 2023 and be completed by June 2023
  • Phase 5 (two components): (1) 16th Street, from K to H Streets, located on Black Lives Matter Plaza – completed in May 2021; and (2) H Street, from 16th to 17th – scheduled to begin February 2022

PILC Project

We have identified the need to replace and upgrade secondary underground power distribution feeders in certain neighborhoods in the District of Columbia. This ten-year project will allow Pepco to increase the reliability and safety of Pepco's underground power distribution system. Specifically, the project requires crews to enlarge older manholes as well as replace aging power cables with new, more modern power cables providing greater reliability for neighborhoods in the future. Overall, the project makes our infrastructure access points in neighborhoods around District of Columbia safer for our employees and community. We have already completed work in Adams Morgan and Mt. Pleasant. The next phase of work scheduled to take place in Eckington. The project includes other neighborhoods in the near future as well and to learn more about this ten-year project please email

G Street Conversion Project

The G Street Conversion Project is a coordinated effort to improve the reliability of service in this community by upgrading equipment that will help increase the amount of electricity we can deliver to our customers. We will be increasing the capacity of our underground distribution lines by replacing existing underground equipment with more modern equipment that can support higher voltage and greater electrical capacity.

Georgetown Conversion Project

In 2016, we began an effort to improve the reliability of service in the Georgetown community by upgrading equipment to increase the amount of electricity we can deliver to our customers. As part of this work, we will be increasing the capacity of our underground distribution lines replacing existing underground power lines and equipment with those that can support higher voltage and greater electrical capacity. Work will begin again in the Georgetown waterfront area in early 2022.

As part of this project, some customers in the Foggy Bottom neighborhood will be transferred to a different, nearby energy source. This upgrade may require changes to some household equipment that runs on 240 Volts. A survey is being conducted in the Foggy Bottom neighborhood to determine the types of appliances currently in use and whether any will require an upgrade.

Harvard Distribution Project

Distribution construction is needed in the Columbia Heights and Adams Morgan neighborhoods to provide expanded capacity to meet the growing energy needs in the surrounding area. This project also will be utilized, as part of the Capital Grid project, to supply service to the Harvard Substation and Champlain Substation in advance of the rebuilding of those substations. The distribution project is planned to occur over several months:

  • November 2021 – July 2022: construction along V Street NW
  • December 2021 – July 2022: construction along Columbia Road NW
  • January 2022 – August 2022: construction along Harvard Street NW and Sherman Avenue NW


Livingston Road Battery Energy Storage Project

We are constantly evaluating new technologies and services to build a smarter energy grid to further improve service for our customers. The Livingston Road Battery Energy Storage Project includes installing a battery storage system at our Livingston Road Substation in Oxon Hill, Maryland. The project will improve the reliability and quality of energy service for thousands of customers in the greater Oxon Hill area when customer demand for energy is highest.

Project construction is expected to begin in 2022.

Ft. Washington and Clinton 69KV Reliability Enhancement Project

Given the growing threats from severe weather and more powerful storms, we are making strategic upgrades to modernize the local energy grid. As part of this effort, we will be upgrading overhead distribution line in Clinton and Ft. Washington, Maryland to make it more resilient and reliable for our customers. We also will be using stronger utility poles and more modern equipment to benefit customers in these areas. Construction activities are tentatively scheduled to begin in spring 2023 and are expected to take approximately 18 months.

White Flint Substation

Pepco plans to construct a new substation in the rapidly growing North Bethesda/White Flint area to deliver safe, reliable, affordable and sustainable energy to nearby families and business. Substation work began in 2020 and associated overhead and underground construction along Nebel Street, Marinelli Road, Old Georgetown Road, Citadel Avenue, Randolph Road, and Parklawn Drive will occur or has already taken place. Timelines associated with portions of this project have been adjusted and work is expected to be completed in 2024.

As part of this project, on August 30, 2021, we began a 6-month construction effort on the westbound lanes of Randolph Road, between Nebel Street and Parklawn Drive. We are committed to working closely with our customers and communities to address questions and minimize any potential impacts, and to keeping the community informed about our progress. Please note, construction work on Randolph Road has been extended to April 2022. Details about this change are outlined in the community letter below. A project fact sheet, community meeting presentation and project map about the Randolph Road construction are also available below.

Prince George's County 69KV Central Avenue Upgrade

As part of our ongoing commitment to provide safe, reliable and affordable electric service for our customers, we have identified the need to replace and upgrade existing overhead electrical equipment in Prince George's County, Maryland. In 2018, Pepco began replacing wooden transmission poles with stronger steel poles. These upgraded poles are not only more resilient but also more resistant to storm damage. The work will span approximately 5.9 miles and will take place mostly along Central Avenue in Prince George's County between Campus Way, Watkins Park Drive and Shady Glen Drive. This upgrade project will take approximately 12 months to complete, with the majority of the work in public spaces as well as Pepco's existing right-of-way.
