South Pittsburg, Tennessee

Power Supply Upgrade

December 2013

Land survey has been completed.

July 2013

TVA has evaluated several options for a new transmission line that will provide power to Sequachee Valley EC's new South Pittsburg 161-kV Substation, which will in turn power new industrial expansion in the area.

image of transmission towerThe same considerations — environmental, land-use, engineering, and cultural — 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, 7, 9, 11 and 12 as the preferred route (see map). Some segments have been adjusted from what was presented at the open house due to public input. The preferred location for tapping the existing TVA transmission line is alternative #2, located near Burns Island Road.

The new South Pittsburg Substation would be located on East 10th Street on the old National Guard Armory site.  TVA would provide power to the new substation via a 4.5-mile line from the Nickajack-Raccoon Mountain 161,000 volt line.

The line would consist of steel structures on a 100-foot-wide right of way. Construction is scheduled to begin May 2015 with the transmission line in service November 2015.

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

April 2013

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

Additional power is needed for growing industrial load in Marion County, Tennessee. Sequachee Valley EC plans to build a new substation. TVA would build a transmission line to provide power to the substation.

TVA held an open house on April 25, 2013 to provide information, answer questions and accept comments about the proposed transmission line.

The proposed project consisted of four to six miles of new transmission line. The line would extend from TVA's existing Nickajack-Raccoon Mountain 161-kilovolt Transmission Line to Sequachee Valley Electric Cooperative's new substation, to be located off East 10th Street on the former National Guard Armory property.

TVA considered several alternative routes. The line would be built on steel pole structures centered on a 100-foot right-of-way.

The project is expected to be in service May 2015. Construction would begin May 2015.

Public involvement

TVA held an open house to discuss the proposed transmission line project on Thursday, April 25, 2013 in South Pittsburg, Tennessee. TVA representatives were available to provide information, answer questions and received comments associated with this proposal. Comments received, including names and addresses, are part of the administrative record and will be available for public inspection.

TVA's process for locating new transmission projects is designed to allow public input at all stages. TVA is committed to working with area stakeholders to address concerns during the course of the project. Comments received during the comment period were used in reaching a decision on the proposed action.


The map shows the preferred route, as well as the network of alternative routes TVA considered for the proposed transmission line. The map is also available below as a PDF.
