Belvoir-Gum Springs

Dominion Energy Virginia is committed to meeting our obligation to provide safe and reliable service to its customers. In order to comply with current safety and clearance standards, we are planning to replace an aging 230-kV (kilovolt) transmission line along a 2.6-mile stretch between its Belvoir and Gum Springs Substations in Fairfax


July 2018 - See updated restoration plan

Due to extensive rainfall in spring 2018, our efforts to restore the right of way corridor have been delayed.


The improved line project will:

  • comply with mandatory reliability standards
  • conform to current safety criteria
  • take advantage of the existing corridor
  • No new right of way required


This rebuild project will include replacing the existing structures and wires with new poles capable of enhancing reliability to area residents and businesses. The existing structures have been in place since the 1960s and have reached the end of their functional life.
