On Sept. 29, 2020, Dominion Energy filed an application for a Certificate of Public Convenience and Necessity with the Virginia State Corporation Commission (SCC) for the Tysons – future Spring Hill Project.


Overview & Benefits

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

Three primary forces drive the need for new or improved transmission infrastructure:

  • Aging assets, such as decades old structures that need to be replaced
  • Compliance with current safety operating standards
  • And, economic development, such as population growth or business expansion

As a result of economic development, local comprehensive planning and consistent with the underground pilot legislation, Dominion Energy is proposing to 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.

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 virtual community meetings to answer questions from residents and area businesses
  • 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.

Frequently Asked Questions

How can residents and business owners in the community become involved in this process?

There will be a virtual community meeting in summer 2020 where the public can hear from our subject matter experts to learn details on 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.

Which legislation called for Dominion Energy to place this overhead line underground?

Pilot Program Amendment

What will be the environmental impact of the line construction?

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.

What interruptions will there be to traffic in an already congested area?

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.

Will Dominion Energy need to acquire new land/property for this project?

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.

How large will the new Spring Hill substation be and who will it serve?

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).
