TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Dickson area of Dickson and Hickman Counties.
TVA has determined that, in various maintenance contingency scenarios, the Dickson area transmission system is overloaded and experiences interruption in electrical service. Three existing Dickson Electric System (DES) stations in the area are on radial feeds. This project would remove these stations from radial feeds, provide increased transmission capacity for future load growth, improve operational and maintenance flexibility, and increase reliability in the area.
TVA proposes to build the Locust Creek 161-kilovolt Switching Station and the Dickson-Locust Creek 161-kilovolt Transmission Line. The proposed line would be a total of about 14 miles long—about 4.5 miles on the existing right of way and about 9.5 miles on the new right of way.
TVA’s new Locust Creek Switching Station will be located about 4 miles south of Bon Aqua within 5 tenths of a mile of the intersection of TVA’s existing Davidson-West Centerville 161-kilovolt and the Tap to Bon Aqua 161-kilovolt Transmission Lines. TVA will build the new switching station and sections of new transmission line utilizing both existing and new right of way. TVA will also reconductor existing lines to create the Dickson-Locust Creek 161-kilovolt Transmission Line.
The existing 5-mile-long Davidson-West Centerville Tap to Bon Aqua Transmission Line will be reconductored and OPGW installed. TVA’s new Locust Creek Switching Station will be built near the intersection of the Davidson-West Centerville Transmission Line and the Tap to Bon Aqua line. These 3 lines will terminate in the new switching station. This may require tear down of existing single-circuit line and rebuild as double-circuit. Up to 4 tenths of a mile of new right of way will be required to route the new lines to the new station.
There are 31 alternative line segments and 2 switching station sites under consideration.
Property owners near and along the alternative transmission line segments have been invited to a virtual open house by mail—including about 237 property owners representing about 322 parcels.
The virtual open house is available from February 4 through March 8, 2021 at www.tvavirtual.com/dickson.
Property owners and members of the public are invited to submit comments and questions about this proposed transmission project through March 8, 2021.
The project is expected to be in service in fall 2025. Construction is scheduled to begin in spring 2024. (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)

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 Spencer Whittier. All written comments on this proposed action should be sent to TVA no later than March 8, 2021. (See contact information below).

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.
