Patriot Substation and 100-kV Transmission Line

Patriot Transmission Line and Substation Project

Meeting the growing energy needs of Anderson County.

Update

Selected route has been chosen (see below).

Project Overview

Anderson County has seen steady growth and an increased demand for electricity over the past several years. To help meet the community’s growing energy needs and provide the reliable, affordable and increasingly clean energy our customers deserve, upgrades are essential.

The Patriot Transmission Line Project will help strengthen the grid and increase electric capacity for customers now and in the future. The project includes constructing a new 100-kilovolt (kV) transmission line and new substation.

The Patriot Substation will be located near the intersection of Mountain Springs Road and Highway 81. A new transmission line will be required to connect the new substation to the existing energy network.

Route Selection

We have appreciated your patience and professionalism as our project team carefully evaluated the alternative routes that we presented to you at the March 7, 2023 open house.

Choosing the best route for this new transmission line was a challenging process and one that was not taken lightly. Many factors were considered during the route study and siting process, including land use, engineering, natural resources, safety, reliability and community input collected during two open house meetings and during the public comment periods.

Selected Route

The selected route consists of segments C, D and B as they were presented at the open house on March 7, 2023 as well in the previous notification and interactive map. After connecting with our existing infrastructure near the Wrenn Substation on the eastern side of I-85, the route will then cross Elrod Road before going over I-85. On the west side of I-85, the line projects north before turning to the west to cross Old Williamston Road. After turning to the north once more, the transmission line will run west where it will cross Timms Road, then head north towards Little Brushy Creek. From there it will head northwest where it will cross Mountain Springs Road before crossing Highway 81 and finally connecting with the new substation.
