Landstown-Thrasher Rebuild

At Dominion Energy, we are committed to continually reviewing and analyzing our energy infrastructure to provide the most safe and reliable electric service. We are currently exploring options to address an aging 230 kilovolt (kV) electric transmission line located in the cities of Chesapeake and Virginia Beach. The line has been in service for over five decades and needs to be replaced to maintain reliability for our customers.


On Dec. 4, 2018 the Virginia SCC issued a Final Order in the Landstown-Thrasher, approving the project, construction is anticipated to begin July 2020.

On June 25, 2018, Dominion Energy filed an application for a Certificate of Public Convenience and Necessity with the Virginia State Corporation Commission


Project 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


This project will rebuild an existing 230 kilovolt line located in the cities of Chesapeake and Virginia Beach. The 8.5-mile line connects our Landstown and Thrasher substations. The project will replace a total of 46 structures on this stretch of line – including 44 steel lattice structures. These existing structures stand 111 feet tall on average and are located in an existing 120-foot right of way corridor. The line has been in operation for over five decades and needs to be replaced to ensure the integrity of the electric grid.

SCC Approval Process

June 25, 2018 - Filed 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.
