TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in Knox and Loudon Counties in Tennessee.
TVA proposes to build from 5 to 6.5 miles of single-circuit 161-kilovolt transmission line. The new line would begin at TVA’s Watt Road-Oak Ridge National Laboratory 161-kilovolt Transmission Line at one of three tap points, one of which is in a double-circuit portion with TVA’s Fort Loudoun-Watt Road 161-kilovolt Transmission Line. The new line would then extend northeast to the new station.
Lenoir City Utilities Board currently provides distribution service in and around the Hardin Valley, Tennessee area with the Solway 161-kilovolt Station. The Solway Station is soon projected to exceed its guaranteed capacity. In addition, distribution lines supplying the Hardin Valley area are becoming overloaded due to steady growth in the area. Further, the nearby Watt Road and Karns 161-kilovolt Stations are heavily loaded and do not have significant ties to the area to shift load from the Solway Station. The Hardin Valley area is the fastest growing area in Knox County, with a population growth rate averaging about 3.9 percent from 1990 to 2017. Construction of new homes in the area has increased significantly since 2012, with an average of 220 new dwellings annually from 2012 to 2017, and that number continues to rise over the last three years. In order for Lenoir City Utilities Board to continue to provide reliable and quality power, upgrades to the distribution system are essential.
Building the new Hardin Valley 161-kilovolt Station would resolve capacity issues at the Solway 161-kilovolt Station by allowing the load to be transferred from this station to the Hardin Valley Station. Additionally, the new Hardin Valley Station would provide enhanced reliability due to a reduced amount of distribution line exposure.
This project would increase power reliability and support the growing load in Knox and Loudon Counties.
There are three alternative tap points:
The proposed new line would utilize primarily steel, single-pole structures centered on a new 100-foot-wide right of way.
Property owners near and along the alternative transmission line routes have been invited to the virtual open house by mail, including about 198 property owners representing about 325 parcels.
Property owners and members of the public are invited to submit comments and questions about this proposed transmission project through November 23, 2020.
The project is expected to be in service in winter 2022-2023. Construction is scheduled to begin in summer 2022. (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 considered 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 and will be available for public inspection.
If you cannot access the virtual open house but have questions or comments, contact Todd Liskey (see contact information below). All written comments on this proposed action should be sent to TVA no later than November 23, 2020.
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).

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.
