Current Reliability Projects

White Flint Substation

Pepco will be constructing a new substation in the rapidly growing White Flint area to deliver safe, reliable, affordable and sustainable energy to nearby families and business. Substation work started in 2020 and associated line work will be performed with overhead and underground construction along Nebel Street, Marinelli Road, Old Georgetown Road, Citadel Avenue, Randolph Road, and Parklawn Drive. This work is expected to be completed by December 2023. 

69KF Reliability Enhancement Project – Ft. Washington and Clinton, Maryland

Pepco is committed to providing our customers with safe and more reliable energy service. Given the growing threats from severe weather and powerful storms, we are making strategic upgrades to modernize our energy infrastructure. As part of that 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.

Benning Area Plan

At Pepco, we are committed to providing safe, reliable, affordable and sustainable energy to our customers and communities in the District of Columbia. Consistent with this commitment, we are executing the Benning Area Plan –  a coordinated effort to improve the reliability of service in your community by upgrading equipment such as utility poles and overhead lines and adding new technology to the system. We will also be adding new feeders to the system, which will increase capacity to meet the area's growing demand for electricity.

Capital Grid

We are committed to delivering safe  and reliable energy to our customers and communities in the District of Columbia and Maryland. Part of this commitment includes actively managing and maintaining the existing electric system and planning for the future needs of our customers. The Capital Grid Project that we are proposing is an integrated solution that will strengthen the Capital area's electric system, promoting enhanced reliability and resiliency.


PILC Project

As part of our ongoing commitment to provide safe, reliable and affordable electric service to our customers, 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 man holes as well as replace aged power cables to newer 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 with 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 PILCproject@pepco.com.

Capitol Hill Conversion Projects: E Street, G Street, and Benning to HIll East Feeder Extension

At Pepco, we are committed to providing safe, reliable, affordable and sustainable energy to our customers and communities in the District of Columbia. The Capitol Hill Conversion Project is a coordinated effort to improve the reliability of service in your 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 converting existing underground cables at a lower voltage to new cables with a higher voltage and greater electrical capacity.

Harrison Street Substation

We are always working to provide safe, reliable electric service to our customers and to support the needs of the region.  As part of this commitment, Pepco is upgrading the Harrison Street substation in the Friendship Heights area of Washington, D.C.  Related to this project will be the upgrade of underground supply feeders to the substation. 

Harvard Distribution

At Pepco, we are committed to providing safe, reliable, affordable and sustainable energy to our customers and communities in the District of Columbia. The Harvard Distribution Project will be used to improve the reliability of nearby Fort Slocum Substation feeders, as well as to provide load relief in the surrounding area. This project also will be utilized, as part of the Capital Grid Project, to supply Harvard Substation load in advance of the substation rebuild. The distribution project is planned to occur over several months with construction beginning in mid-October of 2018.

Waterfront Substation

We are always working to provide safe, reliable, and affordable energy to our customers, and to support the needs of the region. As part of this commitment, Pepco identified the need to construct a new distribution substation within Ward 6, Buzzard Point area of the District of Columbia. The Waterfront Substation is needed to support existing customers and planned development in the Capitol Riverfront and Southwest Waterfront areas, and to replace aging infrastructure. The new substation was placed in service in December, 2017, and is currently serving customers in the area.

The substation features a sculpture by David and Eli Hess ("Flashpoint") and murals by District-based artist Katherine Mann, which were developed in collaboration with the DC Commission on the Arts and Humanities and the community.

Prince George’s County 69KV Central Avenue Upgrade​

As part of our ongoing commitment to provide safe, reliable and affordable electric service to our customers, we have identified the need to replace and upgrade existing overhead electrical equipment in Prince George’s County, Maryland. Beginning in May 2018, Pepco will start to replace wooden transmission poles with stronger steel poles. These upgraded poles are not only more resilient but also more resistant to 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.​

Ashford Drive Reliability Work

We will be replacing and upgrading existing underground electrical equipment on Ashford Drive in Prince George's County, Md. Beginning on or around Aug. 1, 2021 Pepco will begin construction in the road at 5025 Ashford Drive and work toward the intersection of Ashford and Roblee Drive. Construction will consist of digging 150 feet of trench each day to install conduit for underground lines. We will haul away existing asphalt and dirt from the trench and each day we will secure the roadway with steel plates. After we have completed the installation of conduit, we will encase the conduit in concrete, backfill the trench and restore the roadway. Construction hours will be Monday to Friday from 9 a.m. – 3:30 p.m. and Saturday from 7 a.m. to 3 p.m. We anticipate completing this project by the end of September 2021. During construction work hours in active areas, residents should remove all vehicles from the street.
