Greenwich Thalia Lynnhaven
230 kV Rebuild Project
Overview
At Dominion Energy, we are committed to providing the reliable, affordable, and increasingly clean energy that powers your every day. To replace aging equipment and maintain reliable service for our customers, we are preparing to rebuild an existing 230 kilovolt (kV) electric transmission line in the City of Virginia Beach, Virginia between our Lynnhaven and Thalia substations. This project will also partially rebuild the line between our Thalia and Greenwich substations. We will replace the existing concrete monopoles with single circuit steel monopole structures.
This construction will occur along a five-mile corridor and remain within the existing right of way while crossing Interstate 264 and S. Independence Blvd. Preconstruction activities between our Greenwich and Thalia substations are planned for Late September/early October 2024, and construction is scheduled to begin in October 2024. Preconstruction activities between Thalia and Lynnhaven substations are expected to begin in November, and construction is scheduled to begin in January 2025.
We are dedicated to working safely and courteously in your community. Thank you for your patience while we complete this important reliability project.

FAQs
You can contact us by calling 888-291-0190 or by sending an email to powerline@dominionenergy.com.
Dominion Energy has more than 6,700 miles of overhead transmission lines. The proposed project seeks to replace existing overhead concrete structures with new overhead galvanized steel monopole structures within the existing right of way. In doing so, the line will be rebuilt to current safety and industry standards.
The existing line is built on concrete monopole structures. The line will be rebuilt primarily using galvanized steel monopole structures. The average height of the existing concrete structures is approximately 88 feet; the average height of the new steel monopole structures is 103 feet. The increase is due to larger spacing between conductor arms based on new structure standards.
Our forestry team will survey trees in the area to identify danger trees that need removal. Danger trees are trees outside the right of way, and possibly on your property, that have the potential to fall within 10 feet of the transmission wires or structures. Trees and tree limbs that come in contact with electric lines are a leading cause of power outages, especially during storms. The removal of danger trees is necessary to help prevent large scale outages in your community.
If we need to access your property, our forestry team or authorized contractors will contact you. We are committed to working safely and courteously on your property. If you have questions or concerns about the right of way corridor, please email etrow@dominionenergy.com or call 800-215-8032.
Dominion Energy completes an evaluation of potential environmental, cultural and historical impacts of the project. We will work with local, state and federal agencies to complete these evaluations and mitigate any impacts. Permitting agencies on transmission line projects typically include the U.S. 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.
Legal
SCC Application
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 February 24, 2023, Dominion Energy filed its application with the SCC.
