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 July 26, 2024, Dominion Energy filed its application with the SCC. The SCC issued its Final Order approving the project on August 8, 2025.
