Red Hills-Leake Transmission Project, Southwest Mississippi Service Area

Update - March 2015

TVA has identified the preferred route for a transmission line that would increase power reliability for the areas served by the Central Electric Power Association (Central EPA) and 4-County Electric Power Association.

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 would build a 34.8-mile 161-kV line from the existing Red Hills Substation to Central EPA’s upgraded Kosciusko Substation. The line would then continue to the Leake-Singleton 161-kV Transmission Line, creating the new Red Hills-Leake 161-kV Transmission Line. The route selected is a combination of alternative segment Nos. 2, 3, 7, 9, 13, 15, 23, 27, 30, 32, 38, and 39.

The line would consist of steel pole structures on 100-foot-wide right of way. The National Environmental Policy Act review is expected to be completed in fall 2016. Construction is scheduled to begin in fall 2017, and the project is scheduled to be complete in fall 2018.


TVA is considering improvements to its transmission system that would increase power reliability for the area and enhance overall reliability of the TVA system.

 TVA is proposing to build about 55 miles of transmission line from it’s Red Hills Substation to Central EPA’s upgraded Kosciusko Substation then continue the line to connect to the Leake-Singleton 161-kilovolt transmission line. This would create a new Red Hills-Leake 161-kilovolt transmission line that powers three local substations, improves reliability and resolves overload issues.

Forty alternate line segments are under consideration. Some alternatives use existing right of way. The line would be built on steel pole structures.

TVA will hold open houses on Sept. 8-9, 2014 to provide information, answer questions and receive comments about the proposed transmission project.

The project is expected to be in service summer 2019. Construction is scheduled to begin spring 2017. (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)

Public involvement

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

TVA will hold open houses to discuss the proposed transmission project. Details are as follows:

Monday, Sept. 8, 2014

3:00 - 7:00 p.m.
Choctaw County Community Center
898 College Street
Ackerman, Mississippi 39735

Tuesday, Sept. 9, 2014

3:00 - 7:00 p.m.
Attala County Coliseum
550 Highway 12 East

TVA representatives will be available at the open house to provide information, answer questions and receive comments. Large maps showing the alternative locations for the transmission upgrades will be available.

TVA is interested in receiving comments concerning how this project may affect the environment, historic properties or any other issues associated with this proposal. Any comments received, including names and addresses, will become part of the administrative record and will be available for public inspection.

If you have special needs, please contact Tanya Adams at least five days prior to the meeting toll-free at (800) 362-4355.

If you cannot attend the meeting but have questions or comments, contact Chris Austin (see contact information). All written comments on this proposed action should be sent to TVA no later than October 10, 2014.

Environmental reviews

A National Environmental Policy Act review has been 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. See the environmental document.

Efforts are made during the siting process to avoid or minimize impacts to floodplains and wetlands in accordance with Executive Orders 11988 and 11990. Floodplain and wetlands along with alternative routes are shown in the referenced map. The map illustrates how each alternative 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.
