Septa-Yadkin
Project Overview
We are proposing to rebuild an aging 500 kilovolt (kV) electric transmission line between our Septa and Yadkin substations. The structures and related components along this 33.1-mile corridor running through Isle of Wight, Suffolk and Chesapeake, Virginia, have reached the end of their life service and need to be replaced to maintain reliability. This project requires no new right of way.
Community Meeting
You are invited to our community meeting to learn more about the Septa-Yadkin 500kV Electric Transmission Project. Our project team members will be in attendance to discuss routing options, answer your questions and review project plans.

Documents
Legal
The Virginia State Corporation Commission (SCC) is responsible for verifying the need, determining the route, and reviewing the environmental impact of certain transmission lines in Virginia. Key filing documents will also be available on this page.
On June 5, 2025, Dominion Energy filed its application with the SCC. Documents related to the case are available to the public on the SCC Docket of the SCC website or search by Case No. PUR-2025-00104 in the Search Cases section. In addition, interested parties may visit the SCC Case Comments page where individual mailboxes are available for each case accepting public comments. Please note, the mailbox may not be available until a scheduling order is issued, typically several weeks after an application is filed.
