Loudoun-Ox Partial Rebuild Project

At Dominion Energy, we are dedicated to finding the best solution for long-term energy needs within the communities we serve. It has become necessary to address an aging electric transmission line, which has been in operation for more than five decades, between our Loudoun Substation in Loudoun County and our Ox Substation in Fairfax County. The rebuild will bring facilities up to current reliability and safety standards.



  • On June 2, 2020, the SCC issued its final order approving the Loudoun-Ox transmission project.
  • On May 1, 2020, the Hearing Examiner’s Report was issued recommended the Commission approve the proposed project.
  • On Sept. 17, 2019, the SCC issued its Procedural Order for the Loudoun-Ox Rebuild Project.
  • On August 13, 2019, Dominion Energy filed an application for a Certificate of Public Convenience and Necessity with the Virginia State Corporation Commission (SCC) for the Loudoun-Ox Rebuild Project.


  • Requires no new right of way
  • Replaces the line to meet current electrical need and safety requirements
  • Removal of approximately 8.5 line miles co-located within the right of way - reducing the number of structures in corridor


The portion of line proposed for rebuild is approximately 19 miles in length and runs parallel with other transmission lines within an existing corridor. As a result of this project, we will also remove approximately 8.5 line miles co-located within the right of way – reducing the number of structures in the corridor.

Community Engagement

At Dominion Energy, we are committed to keeping our neighbors informed about energy needs where they live and work.

As the project develops, we will:

  • Continue outreach by communicating with legislators, homeowners associations and other identified stakeholders
  • Host two, local open houses with property owners, homeowners associations and the public
  • Provide ongoing communications through informational materials, mailings, email updates and a project website

SCC Approval Process


The Virginia State Corporation Commission (SCC) is responsible for verifying the need, determining the route and reviewing the environmental impact of certain transmission lines in Virginia.
