Power Supply Upgrade

Update – June 2014

TVA has evaluated several options for a new transmission line that will provide power to Caney Fork Electric Cooperative’s new Spencer 161-kilovolt Substation, which will in turn provide more reliable power and allow for new industry in the area.

powerlinespowerlinesThe same considerations — environmental, engineering, and social — were used to assess each alternative. The reviews were based on available data, aerial photography, onsite reviews, public review and comment, and property owners' input. Based on these evaluations, TVA has identified alternative route segments 1, 2, 5, 7, 12, 15, 18, 20 and 21 as the preferred route (see map).

The Spencer Substation is located at the intersection of Drake Shockley Road and Industrial Parkway. TVA would provide power to the new substation via a 4.75-mile line from the Watts Bar – Great Falls 161-kV Transmission Line. The preferred location for tapping the existing TVA transmission line is alternative #1, located near the intersection of Lamont-Yates Mountain road and the Watts Bar – Great Falls 161-kV Transmission Line.

The line would consist of steel structures on a 100-foot-wide right of way. Construction is scheduled to begin spring 2016 with the transmission line in service June 1, 2016.

In keeping with TVA's environmental stewardship, appropriate National Environmental Policy Act review will be conducted.

Background – January 2014

TVA is considering improvements to the transmission system in the Spencer, Tennessee area.

New transmission facilities are needed to replace outdated equipment and provide for growing load in the area. Caney Fork EC plans to build a new substation. TVA would build a transmission line to provide power to the substation.

Public involvement

TVA is committed to working with area stakeholders to address concerns during the course of the project. Comments received during the comment period will be used in reaching a decision on the proposed action.

TVA held an open house on January 23, 2014 in Spencer, Tennessee to provide information, answer questions and receive comments about the project.


The map shows the network of alternative routes TVA is considering for the proposed transmission line. The map is also available below as a PDF file.
