This project will rebuild an existing 230 kilovolt (kV) electric transmission line from Dominion Energy’s Lightfoot Substation east of Toano, Virginia nearly four miles to Waller Substation on Waller Mill Road. We propose using single circuit steel H-frame structures. The project also includes rebuilding an existing 230 kilovolt (kV) electric transmission line from Dominion Energy’s Waller Substation approximately 6 miles to the Kingsmill Substation. We propose using single circuit steel H frame structures. For a short distance, less than two miles, we propose to rebuild using double circuit H-frame structures from Kingsmill Substation to the Skiffes Creek Substation.

This full rebuild project is approximately 12 miles long and generally south of interstate 64 and north of Williamsburg.

The project is necessary to replace aging infrastructure. After nearly five decades of service, the structures and related components are at the end of their service life and need to be replaced to maintain reliability for our customers.

Along the project route, the new structures will be taller than the existing structures.

For this project, we will replace aging infrastructure with new electrical equipment in an existing right of way. This equipment will ensure the continued integrity of the electrical grid.

Along this 12-mile-long project we will replace wooden H-frame structures with steel H-frame structures from Lightfoot to Waller. We also plan to remove an existing 115kV transmission line.

From Waller to Kingsmill Substation we plan to replace wooden H-frame structures with steel H-frame structures. We also plan to remove an existing 115kV transmission line.

For a short distance, less than two miles, we propose rebuilding the transmission line between Kingsmill Substation and Skiffes Creek Substation using double circuit steel H-frame structures.

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.
