The project would add and upgrade equipment at the existing switching station on E. Abingdon Drive in Alexandria, and connect it to the Glebe Substation on S. Glebe Road in Arlington. The project does not involve the nearby former NRG Potomac River Generating Station, which is permanently closed.
In September 2014, the Underground Transmission Line and Substation Working Group held its first meeting to examine the effects of a proposal by Dominion Virginia Power to construct a new 230-kilovolt, underground transmission line between Alexandria and Arlington County. The Working Group discussed its mission and received a presentation from Dominion Virginia Power on the need for the project. Dominion Virginia Power considered six electrical alternatives as part of its proposed project. Dominion's preferred alternative involves building a new transmission line between Dominion's Glebe Substation located in Arlington County, and Pepco's Station C Substation at the NRG site where the power plant was recently shut down. Dominion Virginia Power identified nine preliminary alignments for the new transmission line connecting these two substations. Dominion indicated that they intend to file with the State Corporation Commission by the end of November for the project.
The project is being phased to allow for utility relocation before the roadway construction. The Phase I design has been completed, and construction will begin in Spring 2016 and will be completed in Fall 2016. Once Phase I construction is completed, existing utilities will be relocated before construction of Phase II begins. The utility relocation is expected to take 10-12 months and should be completed in Summer 2017
The construction schedule is as follows:
- Phase I Construction begins: Fall 2015
- Utility Relocation begins: Summer 2016
- Phase II construction begins: Fall 2017 (Construction duration is 18 months)
The current plans can be reviewed at City of Alexandria City Hall, 301 King Street, Room 3000. Property impact information is also available for your review.
