230 kV Electric Transmission Line

Global Plaza Extension

Improving the reliability and meeting growing needs in Loudoun County.

To support continued growth and maintain reliable electric service in Loudoun County, a new double-circuit 230 kV transmission line is proposed to connect two existing transmission lines. The project will require approximately 1.5 miles of new right of way, but no new substations.

Project Details

This project proposes to build a new, double-circuit 230 kilovolt (kV) transmission line that would connect two existing transmission lines. Approximately one and a half miles of new right of way is required for this project, and multiple routes are being evaluated that would go through industrial and commercial area. This project will not require new substations.

Public outreach and engagement will start in the fall of 2026. The project requires approval from the Virginia State Corporation Commission (SCC), and we expect to file an application in early December 2026. Construction is expected to last from mid-2028 through late 2029 with the new lines being in service by the end of 2029.

This project is being designed and constructed to meet today's safety and reliability standards – so you can get the power you need when you need it.
