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.)
