Gallatin, Tennessee (North Gallatin)

Proposed Transmission Project

TVA is considering improvements to its transmission system in order to provide power for growing load and increase power reliability in the Gallatin area of Sumner County.      

TVA would build the North Gallatin 161-kilovolt Substation about one-half mile east of the eastern end of Gateway Drive and about one-half mile south of Roundtree Drive.

TVA would also build from 5.7 to 7.1 miles of double-circuit power line beginning at TVA’s Gallatin-Portland 161-kilovolt Transmission Line. The new line would extend east initially and then south to the proposed North Gallatin Substation.

There are four alternative line segments under consideration for the route of the new transmission line. The line would be built using primarily steel, two-pole structures centered on a combination of existing and new TVA right of way as follows:

  • Existing 300-foot-wide right of way (originally acquired for the Montgomery-Wilson, Loop into Hartsville, Montgomery-Hartsville Section).
  • New 100-foot-wide right of way would be acquired for either the last approximately 1.9 miles of Segment 2 or all of Segment 3 and then all of Segment 4.  This new right of way would be necessary to exit the existing east-west right of way and extend south toward the new substation.
  • Route 1 (consisting of Segments 1, 2, and 4) would utilize about 4.8 miles of existing right of way and would require about 2.3 miles of new right of way for an overall route length of about 7.1 miles.
  • Route 2 (consisting of Segments 1, 3, and 4) would utilize about 2 miles of existing right of way and would require about 3.7 miles of new right of way for an overall route length of about 5.7 miles.

This area is served by the Gallatin Department of Electricity and Cumberland Electric Membership Corporation. 

Property owners near and along the alternative transmission line segments have been invited to a virtual open house by mail – including about 165 property owners representing about 225 parcels.

The virtual open house is available from January 21 through February 22, 2021 at

Property owners and members of the public are invited to submit comments and questions about this proposed transmission project through February 22, 2021.

The project is expected to be in service in winter 2023-2024.  Construction is scheduled to begin in spring 2023.  (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)

Public Involvement

North Gallatin, Tennessee Virtual Open House
January 21 – February 22, 2021

TVA's process for siting new transmission projects is designed to allow public input at various stages.  TVA is committed to working with area stakeholders to address concerns during various stages of the project.  Comments received during the comment period will be used in reaching a decision on the proposed action.

TVA is interested in receiving comments concerning how this project may affect the environment, historic properties or any other issues associated with this proposal.  Any comments received, including names and addresses, will become part of the administrative record.

If you cannot access the virtual open house but have questions or comments, contact Rob Nidiffer.  All written comments on this proposed action should be sent to TVA no later than February 22, 2021. (See contact information 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.
