Flowood, Mississippi

Update - September 2018

TVA has identified the preferred route for a new transmission line that would provide power for growing load and increase power reliability in the Flowood, Mississippi 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’s new 4.5-mile transmission line would begin at their Sebastopol-Langford 161-kV Transmission Line (just outside Central Electric Power Association’s (EPA’s) Langford Substation) and extend southwest to the new Flowood Substation.  Central EPA’s new substation will be located on the southwest corner of the intersection of Mississippi Highway 471 and Vine Drive.

The route selected consists of segment Nos. 1, 3, 10, 11, 12 and 13 as presented at the open house in April 2018.

The new line would consist of steel poles centered on new 100-foot-wide right of way.  

Surveys of the right of way are scheduled to begin in fall 2018.
Easement purchases are scheduled to begin in fall 2019.
Construction is scheduled to begin in summer 2020.
The line is scheduled to be in service in winter 2020-2021.

Background

VA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Flowood area.

TVA is proposing to build 4-5 miles of single-circuit transmission line to power a new Central Electric Power Association substation in Flowood.  The line would begin at TVA’s Sebastopol-Langford 161-kV Transmission Line and extend southwest to the new substation to be located on the southwest corner of Mississippi Highway 471 and Vine Road.  

There are 6 alternate line routes and 12 alternate line segments under consideration. The line would be built on steel pole, single-circuit structures.

TVA will hold an open house on Thursday, April 12, 2018, to provide information, answer questions and receive comments about the proposed transmission project.

The project is expected to be in service in fall 2020.  Construction is scheduled to begin in spring 2020.  (Dates are subject to change -- unexpected issues may arise, resulting in the need to adjust the schedule.)

Public Involvement

TVA held an open house in April 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.
