Patriot Substation and 100-kV Transmission Line

Patriot Transmission Line and Substation Project

Meeting the growing energy needs of Anderson County.

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.
