South Macon-Scooba-DeKalb, Mississippi

Proposed Transmission Project

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Macon, Scooba, and DeKalb, Mississippi areas.      

This project (South Macon-Scooba-DeKalb) is the second phase of a two-phase project.  The first phase consisted of building the Midway-South Macon 161-kilovolt Transmission Line.  TVA held an Open House November 21, 2019, in Macon, Mississippi, and the preferred route was announced in early 2020.

In this second phase, TVA proposes to build the South Macon-DeKalb No. 2 161-kilovolt Transmission Line which would provide the following benefits:

  • Increases dispatch opportunities for Kemper CT Plant to provide power to the local load
  • Improves TVA transmission operational flexibility and supports East Mississippi Electric Power Association’s (EMEPA’s) system improvement plan.
    • Strengthens the resiliency of the transmission system with an additional transmission line serving the southern region of the TVA service area in Mississippi.
    • Provides operational flexibility when maintenance or storm restoration activities are ongoing.
    • Supports EMEPA’s plan to replace the 46-kilovolt Scooba and 46-kilovolt DeKalb District Substations with new 161-kilovolt substations.
    • Provides an additional source into Scooba.
    • Reduces transmission losses.
    • Improves telecommunication capabilities in the area.
  • Increases power capacity in the EMEPA service territory for economic development.
    • Supports industrial site development in the area.

This project would increase power reliability and support the growing load in the Macon, Scooba, and DeKalb, Mississippi areas.

TVA would build from 32 to 34 miles of 161-kilovolt transmission line beginning at TVA’s existing South Macon 161-kilovolt Switching Station on Highway 45 in Macon.  The new line would first extend southeast toward Scooba and then west to TVA’s existing DeKalb 161-kilovolt Substation on Birch Street in DeKalb.  There will be two tap points on the new line for two new EMEPA substations -- the Scooba 161-kilovolt Metering Station to be located on Highway 45 South and the East DeKalb 161-kilovolt Metering Station to be located on Highway 16 West.   

There are 29 alternative line segments under consideration for the route of the new transmission line.

The new line would consist primarily of steel, single-pole structures centered on existing and new 100-foot-wide right of way.  Where necessary, 2- and 3-pole structures will be used, and the existing 75-foot-wide right of way will be widened to 100 feet.  Additional right of way may be needed for transmission line work that will take place outside the Shuqualak 161-kilovolt Metering Station.

Property owners near and along the alternative transmission line segments have been invited to a virtual open house by mail – including about 177 property owners representing about 302 parcels.

The virtual open house is available from December 3, 2020, through January 4, 2021 at  www.tvavirtual.com/DeKalb

Property owners and members of the public are invited to submit comments and questions about this proposed transmission project through January 4, 2021.

The project is expected to be in service in spring 2026.  Construction is scheduled to begin in fall 2022.  (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)

Public Involvement

Virtual Open House

December 3, 2020, through January 4, 2021

www.tvavirtual.com/DeKalb

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 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 will become part of the administrative record.

If you cannot access the virtual open house but have questions or comments, contact Rob Nidiffer. You may submit comments online or mail to the contact below. Written comments must be received by January 4, 2021

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.
