Power Supply Upgrade

July 2013

Land survey has been completed.

March 2013

TVA has evaluated several options for a new transmission line designed to improve electric reliability in the area. Duck River EMC plans to replace aging equipment with a new 161-kilovolt substation. The TVA transmission line would power the substation.

Based on these evaluations, TVA has identified alternative route segments 2, 3, 6 and 8 as the preferred route (see map). The preferred location for tapping the existing TVA transmission line is alternative #2.

The new substation would be located across Ostella Road from the existing substation. TVA would provide power to the new substation via a 4-mile line from the Belfast-Elk Ridge 161-kV line. The line would be located east of Highway 31.

The line would consist of steel structures on a 100-foot-wide right of way. Construction is scheduled for fall 2014 with the transmission line in service December 2014.

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

November 2012

TVA is considering improvements to the transmission system in the Cornersville area. The proposed project includes a new transmission line.

The transmission line is needed to improve the electric reliability of the area by providing power to a new local substation.

The proposed project consists of about five miles of new transmission line. The line would extend south from TVA’s existing Belfast-Elk Ridge transmission line to Duck River EMC’s proposed Cornersville 161-kilovolt substation, to be located across Ostella Road from the existing Cornersville 46-kilovolt substation.

TVA is considering 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 November 2014. Construction would begin summer 2014.

Public involvement

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 will be used in reaching a decision on the proposed action.

TVA held an informal open house to discuss the proposed transmission line project on November 15, 2012. TVA representatives were available to provide information, answer questions and accept comments. A 30-day comment period followed the open house.

Environmental reviews

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.
