Most of the existing structures and components along this 21.5-mile line corridor have been in service for nearly five decades. The line is built primarily on wooden H-frame structures with brown, weathering steel lattice structures and monopole structures in some locations. Due to the age of the wooden H-frames and reliability concerns with weathering steel lattice structures, the line needs to be replaced to maintain reliability for our customers.

We are proposing to replace the existing double circuit weathering-steel lattice structures primarily with brown, weathering-steel monopoles and to replace the existing single circuit wooden H-frame structures with brown, weathering steel H-frame structures with galvanized cross arms and x-braces.

The key purpose of this project is to replace old infrastructure and rebuild to current reliability standards.

Existing Transmission Corridor Conditions:

• Project area is 21.5 miles long
• Right of way is primarily 120 feet wide with some 100-foot sections
• Double circuit monopoles and lattice structures
• Single circuit wood H-frames

• Existing average structure height: 73.3'
• Existing average single-circuit structure height: 64.7'
• Existing average double-circuit structure height: 122.4'

Proposed Transmission Corridor Conditions

• Utilize existing right of way corridor
• Brown, weathering-steel H-frames with galvanized cross arms and x-braces
• Brown, weathering-steel monopoles, and 3-pole structures in some areas

• Proposed average structure height: 79.3'
• Proposed average single-circuit structure height: 71.3'
• Proposed average double-circuit structure height: 125.7'

Note: Proposed structure heights are based on preliminary engineering calculations and are subject to change with final engineering design.

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 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.
