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 500 kilovolt (kV) electric transmission line running from West Virginia into northwest Virginia. The line needs to be replaced to maintain reliability for our customers.
UpdatesFall 2019 - Preconstruction activities such as survey staking, road building, and right of way preparation are ongoing on the West Virginia portion of the project
- 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
- Comply with mandatory standards to ensure safety and reliability
This project will rebuild an existing 500 kilovolt line running southeast from West Virginia’s Grant, Hardy and Pendleton counties into Virginia’s Rockingham and Augusta counties. The line has been in operation for over five decades and needs to be replaced to maintain reliability for our customers. A total of 261 structures will be replaced on the 64-mile line – including 258 brown, weathering steel lattice structures. The new proposed galvanized steel lattice structures will stand 118 feet tall on average, or about 15 feet taller on average than the existing structures.
The line has been in operation for over five decades and needs to be replaced to ensure the integrity of the power grid and maintain reliability for our customers.
SCC Approval Process
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.
