Overview & Project Description

By approximately 2022, load on the existing lines in the Tysons and McLean areas of Fairfax County is forecast to exceed 300 megawatts. By constructing an additional source of power, Dominion Energy will avoid a potential violation of mandatory North American Electric Reliability Corporation (NERC) reliability standards. The Idylwood-Tysons 230 kilovolt (kV) Project is being proposed to enable Dominion Energy to continue to provide reliable power to the area.

Community Engagement

At Dominion Energy, we are committed to keeping our neighbors informed about energy needs where they live and work. As we continue to analyze the various components of the proposed project, it is important that we not only keep you informed, but we hear your feedback.

As the project develops, we will:

  • Continue outreach by communicating with legislators, homeowner associations and other identified stakeholders; and
  • Provide ongoing communications through informational materials, mailings, email updates and a project website.

FAQs

The project team worked with the local community to develop our route recommendation to the Virginia State Corporation Commission. Through two open houses held in Sept. 2017 and one held in Oct. 2019, the public met with our subject matter experts to learn details on the project. As we begin various components of the proposed project, it is important that we not only keep you informed, but we hear your feedback. We invite you to follow the progress of each phase and receive up-to-date project information, including allowable work hours, on our new and interactive web portal.

In addition, you may also contact us and add your address and email to our distribution list.

The new transmission line is being developed in a heavily populated, urban area. The decision to propose an underground line was influenced by space limitations and the potential to require a large amount of new right-of-way which would pose significant impacts on residences, wetlands, parks, and conservation easements.

The Virginia State Corporation Commission Guidelines of Minimum Requirements for Transmission Line Applications Filed Under Virginia Code Section 56-46.1 and The Utility Facilities Act require the Company to provide routing information on viable alternatives. Our legal interpretation of these guidelines, combined with decades of regulatory precedent, confirm that analysis of a viable overhead route must be included in the application if one exists.
As part of our regulatory applications, Dominion Energy completes an evaluation of potential environmental, cultural, and historical impacts of the project. Dominion Energy works with local and state agencies to complete these evaluations and mitigate any impacts. All required permits are obtained and permitting conditions are met. Permitting agencies typically include the US.
