The Tennessee Valley Authority (TVA) on Nov. 27 said that it is seeking public input about upgrades to its transmission system, which involves building about nine miles of new 161-kV transmission line to provide power for growing load and increase power reliability in the Kenlake area of Calloway and Marshall counties in Kentucky.
The new line would begin at a point on TVA’s existing Marshall-Murray 161-kV transmission line and extend southeast to a new substation planned by West Kentucky Rural Electric Cooperative Corporation (WKRECC), TVA said.
As noted on the project’s webpage, the Kenlake area is served by WKRECC, which plans to build the new 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 said in its statement that the new line would be built on steel pole structures on new 100-foot-wide right of way (ROW).
As noted on the webpage, there are two tap points and 24 alternative line segments under consideration for the route of the new line. Both tap point alternatives on TVA’s existing Marshall-Murray 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 project is expected to be in service in summer 2021, with construction scheduled to begin in winter 2020-2021, the webpage added.
An open house about the project will be held on Dec. 6 in Murray, Ky., TVA said.
TVA spokesperson Scott Fiedler on Nov. 30 told TransmissionHub that TVA is planning to invest about $11m on the project, adding that that number may be adjusted once the project is fully scoped.
"Improving the transmission system in this area would provide more reliable power and allow for growth," he said. "All up, TVA is investing $2.2 billion Valley-wide in transmission system improvements over the next five years to continue our mission of providing low cost, reliable power."
According to its website, TVA is also considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Paris, Tenn., and Murray, Ky., areas. Specifically, TVA is proposing to build about 16 miles of transmission line to power a new Paris Board of Public Utilities (BPU) substation in Eagle Creek, Tenn.
That project’s webpage added that the line would begin at TVA’s Murray, Ky., 161-kV substation and end at the new Paris BPU substation adjacent to TVA’s Marshall-Cumberland 500-kV Transmission Line near Tennessee Highway 140.
For 14.5 miles, the new line would parallel the Marshall-Cumberland line and use a portion of existing ROW, requiring 60 feet of additional width. The remaining 1.5 miles of the proposed line would require new 100-foot-wide ROW, the webpage added.
The line would be built on steel pole, single-circuit structures centered on the ROW.
The webpage further stated that the project is expected to be in service in winter 2021, with construction scheduled to begin in summer 2021.
