Pepco Open House on Capital Grid Project Informative

July 19, 2017

Pepco’s open house at E.L. Haynes provided an overview of their upcoming Capital Grid project. The Capital Grid effort is Pepco’s 10 year infrastructure project that is designed to:

  1. Upgrade the power system;
  2. Increase capacity; and,
  3. Network the system.

Generally, the project will rebuild the substations at Harvard Street and Champlain Street, as well as install new transmission lines from Takoma south to the waterfront. The entire project is estimated to be completed by 2026.

The following video by Pepco provides an overview:

Installing the new transmission lines will impact New Hampshire Avenue from the District line to Georgia Avenue, and then south on Georgia Avenue to Gresham Street. There it will travel west to the Harvard Substation. The video below provides an idea of how the work will be performed on Georgia and other area streets.

Pepco has set up a Web page where people can learn more about the Capital Grid project (click here).

Pepco Hosting Open Houses to Discuss Their Capital Grid Project

July 13, 2017

Pepco is scheduling two open houses where we will share information about their Capital Grid project, which will impact Georgia Avenue and other parts of the neighborhood once it gets underway. The project is a 10-year infrastructure plan that is designed to improve reliability across the system, address capacity needs in the growing Capital region, and make the system less vulnerable to strong storms and other unexpected events.

The Capital Grid project includes rebuilding and upgrading the Harvard Substation at Harvard and Sherman.

Their first open house will include a formal presentation at E.L. Haynes Public Charter School on July 18th (see flyer below). After the presentation, there will be an opportunity to speak with Pepco experts about the Harvard Substation construction and learn more about how it may affect the neighborhood. Renderings of the upgraded substation and other components of the project will also be available.

Highlights of the Capital Grid project include:

  • Upgrading three existing Pepco substations (including the Harvard Substation)
  • Building a new substation in the Mount Vernon neighborhood
  • Installing a new 10-mile underground transmission cable that will connect these substations for greater reliability and resiliency against storms

On the evening of May 1st, Pepco hosted Ward 1 Advisory Neighborhood Commissioners to brief them on their upcoming Capital Grid Project. The project’s goal is to build an underground transmission route through the District from the north to the south. This is necessary to create multiple pathways of power supply to connect multiple substations in the Capital area with higher electrical load capacity. In short, this creates a “networked system” that improves reliability and resiliency.

The underground transmission lines will be constructed from the Takoma Substation in Prince George’s County through the District to the Waterfront Substation. The feeders will travel approximately 10 miles, connecting five substations: Takoma, Harvard, Champlain, Mount Vernon (proposed) and Waterfront. The flexibility this will create will support faster service restoration and reduce the potential impact of major unforeseen event.

In our area, work will begin around Fall 2018/Winter 2019 in the area of New Hampshire and Georgia avenues and move south along Georgia Avenue through the Spring/Summer of 2019. On Georgia Avenue, the scope of work will close two of the four lanes as new transmission cables are put underground via trenching. Each night steel plates will cover the trenches. Work will continue down Georgia to Harvard or Gresham, before turning west to the Harvard Street substation.

The Havard Street Substation will also be upgraded and expanded as part of this project, with work commencing as early as 2019 and estimated to be completed around 2022 or 2023.

I will continue to share more information about the construction aspect of this project as we get nearer to the start date. Pepco will also be sharing information directly to the community.

Pepco is currently in the process of improving reliability of electrical service and preparing for a growth in demand for electricity in Ward 1. Their efforts to do this are largely centered on the Pepco substation located at Harvard Street and Sherman Avenue.

To accomplish this, Pepco plans to meet future electrical needs by converting the 4kV underground distributions cables in the area to 13kV cables to enhance service and the system’s reliability. Prior to the work currently being undertaken, Pepco crews have installed nearly 17,600 feet of new conduit and 45,000 feet of new cable. They have also replaced 83 transformers. For their current phase of the project, crews will install/replace approximately 18,000 feet of cable, along with 45 transformers, 4 manholes, 4 switches and additional electrical equipment. The construction began in March 2016 and is scheduled for completion by December 2016. A more detailed fact sheet is available here, and includes the map below:

In addition to the underground power network upgrades, the Harvard Substation also needs to be upgraded. The building contains aging equipment that must be replaced by 2022 in order to meet increased demands for electricity in the area. To facilitate the substation upgrade, Pepco purchased the property to the north (2914 Sherman) and razed it in order to install temporary electric equipment that will continue to provide electrical service while the main substation is off line and being upgraded. The work that still needs to be undertaken is as follows:

  1. Establish temporary electric equipment: The temporary equipment will provide electric service in the area for the entire period the existing substation is out of service during the upgrade. Work to install the temporary equipment will likely start in 2018.
  2. Transfer electric load to temporary equipment: Once established, Pepco will transfer the electric load from the Harvard Substation to the temporary equipment.
  3. Upgrade Harvard Substation: Pepco anticipates the upgrade of the Harvard Substation will begin immediately following the electric load transfer to the temporary equipment and will work with the community to ensure the design of the upgraded Harvard Substation is harmonized with neighboring architectural themes.
  4. Transfer electric load back to the Harvard Substation: After upgrades are completed, the electric load will be transferred back to the upgraded Harvard Substation from the temporary equipment and the Harvard Substation will resume providing electric service in 2022.
  5. Disassemble the temporary equipment. Following the load transfers back to the upgraded Harvard Substation, the temporary equipment will be disassembled.

Additional and future information on the Harvard Substation project — as well as other Pepco reliability projects — is available on the Pepco Web site here.

Pepco’s Beautiful Depression Era Frescoes

March 25, 2015

If you’ve ever had the opportunity to visit Pepco’s Headquarters at Edison Place (701 Ninth Street, NW), you’ll have noticed two large artworks that appear to be paintings. These are actually frescoes created by artist James Michael Newell and commissioned by Pepco in 1931 for their headquarters building at 10th and E Streets, NW. As the Pepco headquarters has moved, so have the frescoes. They now hang at the far end of the entrance hall and nearby in the ground floor elevator lobby on Ninth Street.

The first fresco that a visitor encounters shows linemen working along the Potomac River (below).

Both artworks are accompanied by the following informational plaque:

Here’s some interesting news. Recently, Pepco purchased the property at 2914 Sherman Avenue, NW. This purchase is part of Pepco’s ongoing efforts to provide safe and reliable electric service to residents. As part of their efforts to do this, they identified the need to upgrade the Harvard Substation located at Sherman Avenue and Harvard Street, NW. This substation is an early substation in the Pepco system (it’s no. 13) and was built in five stages. The original 1907 building was designed by architect Frederick B. Pyle. This was followed by additions designed by Arthur B. Heaton in 1920 and 1921. Further additions were added in 1929 and finally in 1944.

According to an email from Pepco,”they have determined that the Harvard Substation needs to be upgraded for several important reasons, including the age of the existing infrastructure and capacity requirements, and to ensure [that they] continue to provide safe and reliable electric service to … customers. The equipment and building itself is aged and needs to be upgraded.  In addition, electrical demand in the area has increased and improvements are needed in order to meet forecasted loads.”

2914 Sherman Avenue will be razed as part of the substation project.

Upgrades to the Harvard Substation must be complete by 2021. To facilitate these upgrades, Pepco purchased the abutting property at 2914 Sherman Avenue. As recently as January 2013, there were plans to renovate the building into 20 market-rate condos. After the developer gutted the building, work seemed to grind to a halt.

Pepco plans to demolish the existing multi-unit building and use it temporarily to complete the renovations and upgrades to the substation. While the project details have not been finalized, Pepco anticipates that the substation improvements will likely proceed in five phases, which they have outlined below:

  • Establish a temporary substation. Before Pepco begins replacing existing infrastructure at the substation, they will first establish a temporary substation on the property adjacent to the substation.  They will need to create a temporary substation so that they can continue to provide electric service in the area while the existing substation is out of service.  Work to construct the temporary substation will likely start in 2018.
  • Transfer electric load to temporary substation site. Once Pepco has established the temporary site, they will transfer the load from the Harvard substation to the temporary substation.
  • Rebuild Harvard Substation. Pepco anticipates the rebuilding work at the Harvard Substation to begin immediately following the electric load transfer to the temporary substation. Plans for the rebuild have not been completed; however, Pepco intends to work with the community to ensure the design is harmonious with neighboring architectural themes and the property use is appropriate for continued operation.
  • Transfer electric load back to Harvard Substation. After the upgrades are completed, the electric load will be transferred back from the temporary substation and the Harvard Substation will resume providing electric service in 2021.
  • Disassemble the temporary substation. Following the load transfers, the temporary substation will be disassembled.

Pepco has determined that upgrading substation no. 13 is essential to maintain and improve the overall reliability and electric service for residents in the communities surrounding the substation.

I’ll share more information about this project as it moves forward and more information is known.
