Horn Lake-Freeport Tennessee

Update – August 2019

TVA has identified the preferred location for a transmission line that would diversify the power flow to the Memphis metro area as well as increase power reliability in the Memphis area.

TVA evaluated each route using social, engineering, and environmental factors. Information sources included available data, aerial photography, limited onsite reviews, public review and comment, and property owner input. Based on public input and evaluation, the preferred route is expected to have the least overall project impacts of the alternatives.

TVA is proposing to build 2.7 miles of double-circuit transmission line to provide power to the existing Freeport Substation on East Windsor Road in Memphis. The proposed line would begin at the existing Allen Fossil Plant-Horn Lake 161-kV Transmission Line near the Tennessee/ Mississippi line and extend east to the Freeport Substation.

TVA is also proposing to add two bays to the Freeport Substation and re-conductor about eight miles of the Allen Fossil Plant-Horn Lake 161-kV Transmission Line from Allen Fossil Plant to the intertie with an Entergy transmission line.

The route selected consists of alternative Tap Point 1 and alternative Segments 2, 5, 9 and 11 as presented at the open house in August 2018.

The new line would consist of steel, double-pole structures centered on a new 100-foot-wide right of way.

Background 

VA is considering improvements to its transmission system that would diversify the power flow to the Memphis metro area as well as increase power reliability in the Memphis area.

TVA is proposing to build 2.7 miles of double-circuit transmission line to provide power to the existing Freeport Substation on E. Windsor Road in Memphis.  The line would begin at the existing Allen Fossil Plant-Horn Lake 161-kV Transmission Line near the Tennessee/Mississippi state line and extend east to the Freeport Substation.

There are 2 tap points, 10 alternative line routes and 11 alternate line segments under consideration. The line would be built on steel pole, double-circuit structures.

TVA is also proposing to add two bays to the Freeport Substation and re-conductor about eight miles of the Allen Fossil Plant-Horn Lake 161-kV Transmission Line from Allen Fossil Plant to the intertie with an Entergy transmission line.
 
TVA will hold an open house on Thursday, August 2, 2018, to provide information, answer questions and receive comments about the proposed transmission project.  The project is expected to be in service winter 2021-2022.  Construction is scheduled to begin fall 2021.  (Dates are subject to change.  During projects, unexpected issues may arise, resulting in the need to adjust the schedule.)

Public Involvement

TVA held an open house in August 2018 to discuss the project and answer questions. 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.

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.
