Update – March 2019
TVA has identified the preferred location for a transmission line that would provide power for growing load and increase power reliability in the Kenlake area of Calloway and Marshall Counties.
TVA evaluated each route using social, engineering, and environmental factors. Information sources included available data, aerial photography, limited onsite reviews, public review and comment, and property owner input. Based on public input and evaluation, the preferred route is expected to have the least overall project impacts of the alternatives.
TVA’s new single-circuit line would connect to TVA’s Marshall-Murray 161-kV Transmission Line south of West Kentucky Rural Electric Cooperative Corporation’s (WKRECC’s) Hardin Substation off State Highway 402/Aurora Highway. The new line would extend southeast to WKRECC’s new substation at the intersection of Highway 94, Green Valley Road and Highland Road.
The route selected is No. 1 which consists of Segments 1, 9, 16, 20 and 23 as presented at the open house in December 2018.
The new line would consist of single, steel poles centered on a new 100-foot-wide right of way.
TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Kenlake area in Calloway and Marshall Counties.
This area is served by West Kentucky Rural Electric Cooperative Corporation (WKRECC). WKRECC plans to build a 161-kV substation in Calloway County south of the Kenlake State Resort Park at the intersection of Highway 94, Green Valley Road and Highland Road.
TVA would build about nine miles of single-circuit, 161-kV transmission line to serve WKRECC’s new substation. The new line would begin at TVA’s existing Marshall-Murray 161-kV Transmission Line and extend southeast to the new substation.
There are 2 tap points and 24 alternative line segments under consideration for the route of the new transmission line. Both tap point alternatives on TVA’s existing Marshall-Murray 161-kV Transmission Line are in Marshall County.
- Tap 1 is located just south of WKRECC’s Hardin Substation located off State Highway 402 or Aurora Highway.
- Tap 2 is located about one mile south of the Hardin Substation east of Trout Road.
The new line would consist of single-circuit, steel pole structures centered on a new 100-foot-wide right of way.
The project is expected to be in service in the summer of 2021. Construction is scheduled to begin winter 2020-2021. (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)
The map shows the area of the proposed transmission improvements. The map is also available below as a PDF file.

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.
