Vonore, Tennessee (Madisonville-Vonore)

TVA is considering transmission improvements that would improve reliability and provide power for growing load in the Madisonville, Vonore, and Greenback, Tennessee areas.  A new power line is needed to serve TVA’s new Vonore 161-kV Station.  This new station will help with voltage issues on existing 69-kV power lines from the Loudon and Fort Loudoun 161-kV Stations.

TVA is proposing to build 8 to 8.5 miles of single-circuit, 161-kV transmission line to serve the new Vonore 161-kV Station.  This proposed line would also serve as a backup power source while the existing 69-kV line, which serves the Vonore 69-kV Station, is rebuilt as double-circuit with the Vonore-Niles Ferry 161-kV Transmission Line.

TVA’s proposed single-circuit line would consist of steel pole structures.  The line would begin in Madisonville at TVA’s Athens-Loudon 161-kV Transmission Line (Tap to Sweetwater, Tap to Madisonville) on the south side of Highway 68 near Fort Loudon Electric Cooperative’s Madisonville 161-kV Station.  The line would then extend 8 to 8.5 miles northeast to the new Vonore 161-kV Station on Old Slag Road.  TVA would utilize existing 50-foot-wide right of way and acquire an additional 50 feet making the right of way a total of 100 feet wide.

The project is expected to be in service in summer 2021.  Construction is scheduled to begin in spring 2021.  (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)

Public Involvement

TVA held an Information Day on April 18, 2019, to provide information and answer questions about the proposed transmission project.


The map shows the area of the proposed transmission improvements. The map is also available below as a PDF file.

If you have questions or need help understanding the map, please contact TVA (see below).

Environmental Reviews

The appropriate National Environmental Policy Act review will be conducted to ensure that the environmental impacts are minimized. TVA attempts to minimize any land requirements, private property impacts, and environmental impacts associated with this project.

Efforts are made during the siting process to avoid or minimize impacts to floodplains and wetlands in accordance with Executive Orders 11988 and 11990. Floodplains and wetlands are shown on the referenced map. The map illustrates how the route avoids or impacts floodplains and wetlands. Because of project and topographic constraints and because of minimizing impacts to other social, environmental, and engineering resources, no practicable alternative may be available that would allow complete avoidance of impacts to floodplains and wetlands which may require mitigation for minimizing impacts. Also, best management practices would be utilized throughout the project to minimize adverse floodplain and wetland impacts. In compliance with Section 404 of the Clean Water Act, TVA will be coordinating wetland findings with U.S. Army Corps of Engineers.
