Glebe Rebuild


On March 7, 2019, Dominion Energy filed an application for a Certificate of Public Convenience and Necessity with the Virginia State Corporation Commission (SCC) to rebuild its Glebe Substation and underground North Potomac Yards.


In 2014, our team began work to address a forecasted reliability concern in the Alexandria-Arlington-Fairfax area, and proposed a new Glebe-Potomac River line project. Updated data on the need for the original project has changed and no longer requires a new line, but requires work at two of our existing facilities in Arlington and Alexandria.

In July 2018, Dominion Energy received an updated base case study from PJM, a regional transmission organization, on load projections through 2023. This updated study revealed several changes to the electrical planning horizon - removing the need for certain work.

In addition to changing the need and scope of the solution, cost was also significantly impacted. Specfically, the estimated cost of the Rebuild Solution decreased from approximately $290 million to approximately $170 million. Alternately, the total estimated cost for the New Line Solution is approximately $340 million.

Following these changes, the New Line is no longer a justifiable solution for the current capacity need. 

The current solution calls for Dominion Energy to rebuild its existing Glebe Substation and underground the North Potomac Yards Terminal Station.
