Tysons Future Spring Hill
Overview
Due to rapid growth and local comprehensive planning, Dominion Energy is placing a portion of an existing overhead 230 kilovolt (kV) electric transmission line underground and constructing a new substation source in the Tysons area of Fairfax County.
This project will underground an existing overhead transmission line between our Tysons Substation on Tyco Road to a new transition pole just south of the future Spring Hill Substation southwest of Leesburg Pike and Spring Hill Road in Fairfax County.
The 230 kilovolt (kV) line is approximately half-mile in length and is consistent with Fairfax County’s Comprehensive Plan and responds to 2019 undergrounding pilot legislation.
Important Update: March 2024
The Vesper Trail is reopened to pedestrian traffic. Please be mindful that there may be construction activity in the area as the project is still ongoing.

Benefits
- Complies with mandatory standards to ensure safety, reliability and to meet future needs
SCC
The Virginia State Corporation Commission (SCC) has regulatory authority over all energy providers in Virginia. 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.
On 9/29/20, Dominion Energy filed its application with the SCC. The SCC issued its Final Order approving the project on 6/24/21. Documents related to the case are available to the public on the SCC Docket of the SCC website or search by Case No. PUR-2020-00198 in the " Search Cases " section. In addition, interested parties may visit the SCC Case Comments Page where individual mailboxes are available for each case accepting public comments.

A virtual community meeting will be held in summer 2020 to allow the public to hear from our subject matter experts and learn details about the project. In addition, the Transmission Application Process Chart outlines how the public can become involved in the Virginia State Corporation Commission (SCC) approval process. You can also contact us to add your mailing address and email address to our distribution list.
As part of the regulatory application process, Dominion Energy completes an evaluation of potential environmental, cultural and historical impacts of the project. Dominion Energy works with local, state and federal agencies to complete these evaluations and mitigate any impacts. All required permits are obtained and permitting conditions are met. Permitting agencies typically include the Army Corps of Engineers, the Virginia Department of Conservation and Recreation, the Virginia Marine Resources Commission, and the Virginia Department of Transportation. Commenting agencies include the Virginia Department of Game and Inland Fisheries and the Virginia Department of Historic Resources, among others.
Our enterprise-wide environmental report describes our commitment to the responsible stewardship of natural resources and provides a wealth of information on environmental management and performance. We also invite you to read our Corporate Environmental Policy and our Greenhouse Gas Report.
The construction plan is to perform all road work at night so impacts will be limited. The proposed "open-trench" method of installing the duct bank will also limit the duration of the road work.
Dominion Energy works closely with VDOT in developing a Maintenance of Traffic plan which limits work hours to non-rush hour times for construction.
There will only be a need to acquire property from the developer of The Views. We will get permits to locate the underground duct bank in VDOT right of way.
The proposed substation will be located on approximately one acre of land. It is planned to be approximately 250’ long by 110’ wide by 75’ tall.
It is planned to generally serve customers south of Route 7 (Leesburg Pike) and outside of I-495 (Beltway).Construction-Related Impacts
