At Dominion Energy, we are committed to continually reviewing and analyzing our energy infrastructure to provide the most safe and reliable electric service.

For about five miles along the W and OD Trail Dominion Energy will replace the overhead wires between the transmission structures. On a shorter section of the project, it’s necessary for Dominion to replace aging lattice structures with new, taller steel double circuit monopoles. This rebuild project also includes one single circuit structure. This transmission project is approximately eight miles long and in the Northwest section of Loudoun County

Three primary forces drive the need for new electric transmission infrastructure:

  • Economic development, such as population growth or business expansion
  • Aging assets, such as decades old structures that need to be replaced
  • And complying with mandatory standards to ensure safety and reliability

These drivers often overlap, and at Dominion Energy, we believe solutions should always account for future energy needs while continuing to balance cost and impacts.

Overview

For this project, we will replace existing conductor with new electrical equipment in an existing right of way. This equipment will ensure the continued integrity of the electrical grid.

Along this 8-mile-long project we will replace the overhead wires between the transmission structures. On a shorter section of the project, it’s necessary for Dominion to replace aging lattice structures with new, taller steel double circuit monopoles. This rebuild project also includes one single circuit structure.

Construction is scheduled to begin in spring 2022 with an anticipated completion date of December 2022

Project Map

Updates

In March 2021, Dominion Energy plans to file an application for a Certificate of Public Convenience and Necessity (CPCN) with the Virginia State Corporation Commission (SCC).

Timeline

  • January – May 2021: Outreach to the community
  • May 6, 2021: Informational Virtual Community Meeting planned
  • May 31, 2021: Project filed with the State Corporation Commission

Goals

  • Create no new right of way
  • Keep structures in the same general location as existing structures
  • Provide long-term reliability and durability without excessive maintenance
  • Deliver operational system flexibility to meet future needs
  • Comply with mandatory standards to ensure safety and reliability

SCC Approval Process

  • March 2021 - anticipated filing date for SCC application

The Virginia State Corporation Commission (SCC) has regulatory authority over all energy providers in Virginia and requires certification for all transmission lines out of the ordinary course of doing business or are at or above 138 kV. Among other responsibilities, the SCC validates the need for a proposed line and approves the route and structures. In reviewing a proposed project, the SCC must consider whether potential impacts on scenic assets, historic districts and the environment have been reasonably minimized.

To learn more about this process, please view our SCC application review process.

Procedural Schedule

The following key dates and developments are related to the SCC review timeline. For the most up-to-date and full listing of motions, rulings and other related documents, please refer to the SCC docket for this case.
