Gallatin Fossil Plant-Angeltown 161-Kilovolt Transmission Line and Switching Station - Power System Improvements

Sumner County, Tennessee

On October 8, 2010, TVA issued an environmental assessment and finding of no significant impact for its proposal to construct and operate a 19.6-mile, 161‑kilovolt transmission line and a switching station in Sumner County.  This action would improve the bulk transmission system and ensure a reliable supply of electric power to TVA’s Gallatin, Portland, and Lafayette power service of Middle Tennessee.  The proposed transmission line would provide an electrical connection between the Gallatin Fossil Plant and a new Angeltown Switching Station.

The transmission line would be constructed on 13.4 miles of new right-of-way (ROW) and 6.2 miles of existing ROW that would be 100 feet wide.  Approximately 163 acres of new ROW would be acquired and cleared for the new line.  Additionally, the switching station would be constructed on approximately 10 acres of undeveloped land.  TVA also proposes to make minor equipment upgrades at several TVA facilities.

Additional information on the project is available including background information, maps, and a project schedule.
