Current TVA Transmission System Projects

Alabama

Nettleton, Mississippi (Lee County)

Update – January 2024

TVA has identified the preferred location for transmission improvements that would provide power for growing load and increase power reliability in the Nettleton area of Lee County in Mississippi. 

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 proposed 7.21-mile line would begin at the Tupelo-Okolona 161-kilovolt Transmission Line north of Old Union Road and south of Coonewah Creek.  The line will extend primarily southeast, staying south of Coonewah Creek, and end at the upgraded 161-kilovolt Nettleton Substation on the north side of Will Robbins Highway in west Nettleton.

The route selected is Route 8 and consists of Segments 2, 4, 6, 10, 12, 13, 19, 20, and 21 as presented at the open house held October 5, 2023, and online at the virtual open house held from October 5 through November 6, 2023.

The new line will be built using primarily steel or concrete, single-pole structures centered on a combination of existing 75-foot-wide and new 100-foot wide right of way.

  • Surveys of the right of way are scheduled to begin in spring 2024.
  • Easement purchases are scheduled to begin in summer 2025.
  • Construction is scheduled to begin in winter 2025-2026.
  • The line is scheduled to be in service in spring 2026.

The National Environmental Policy Act review is pending.

Background

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Nettleton area of Lee County in Mississippi.

Tombigbee Electric Power Association (TEPA) is planning to upgrade their Nettleton, Mississippi 46-kilovolt Substation to 161-kilovolt operation by April 2026.  TVA’s Tupelo-Okolona 161-kilovolt Transmission Line serves the North Shannon 161-kilovolt Substation area.  Presently, TEPA’s Nettleton, Shannon, and Laney Road 46-kilovolt Substations are all fed from a single, 10.2-mile feeder line out of their North Shannon 161-kilovolt Substation.  TEPA is experiencing reliability and capacity issues in the southern part of their service territory.  Capacity is exceeded in extreme peak conditions, and area growth will contribute to these issues.

TEPA’s upgrade of their Nettleton 46-kilovolt Substation to 161-kilovolt operation would be the second step of the solution to these issues. This would allow TEPA to improve flexibility and reliability on their system.  In a separate project and as the first step of TEPA’s solution to these issues, TEPA will also upgrade their Shannon 46-kilovolt Substation to 161-kilovolt operation in spring 2025. The Shannon 161-kilovolt Substation must be in service to provide the flexibility and capacity required to upgrade the Nettleton 161-kilovolt Substation.

TEPA will convert the Nettleton 46-kilovolt Substation to 161-kilovolt operation. 

TVA proposes to build about 6.5 to 8 miles of 161-kilovolt transmission line to serve the upgraded substation.

The proposed power line would begin at one of five tap points on TVA’s Tupelo-Okolona 161-kilovolt Transmission Line and extend southeast to TEPA’s upgraded Nettleton Substation located at 7095 Will Robbins Highway in Nettleton.

There are 5 possible tap point locations and 24 alternative line segments under consideration providing a total of 20 different route options.  The 5 tap point locations are described here:

  • Tap Point 1 is just north of Coonewah Creek near Structure 71.
  • Tap Point 2 is north of Old Union Road, south of Coonewah Creek, between Structures 79 and 80.
  • Tap Point 3 is north of Old Union Road, on the existing right of way, between Structures 78 and 79.
  • Tap Point 4 is off Romie Hill Avenue, near the new Shannon 161-kilovolt Substation.
  • Tap Point 5 is south of County Road 300, between Structures 93 and 94.

The line would be built using primarily single-pole, steel or concrete structures centered on a combination of existing 75-foot-wide and new 100-foot-wide right of way.

TVA will hold an open house on Thursday, October 5, 2023, to provide information, answer questions and receive comments about the proposed transmission project.

The project is expected to be in service in spring 2026.  Construction is scheduled to begin in winter 2025.  (Dates are subject to change.  Unexpected issues may arise, resulting in the need to adjust the schedule.)

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.

TEPA will convert the Nettleton 46-kilovolt Substation to 161-kilovolt operation. 

TVA proposes to build about 6.5 to 8 miles of 161-kilovolt transmission line to serve the upgraded substation.

The proposed power line would begin at one of five tap points on TVA’s Tupelo-Okolona 161-kilovolt Transmission Line and extend southeast to TEPA’s upgraded Nettleton Substation located at 7095 Will Robbins Highway in Nettleton.

There are 5 possible tap point locations and 24 alternative line segments under consideration providing a total of 20 different route options.  The 5 tap point locations are described here:

  • Tap Point 1 is just north of Coonewah Creek near Structure 71.
  • Tap Point 2 is north of Old Union Road, south of Coonewah Creek, between Structures 79 and 80.
  • Tap Point 3 is north of Old Union Road, on the existing right of way, between Structures 78 and 79.
  • Tap Point 4 is off Romie Hill Avenue, near the new Shannon 161-kilovolt Substation.
  • Tap Point 5 is south of County Road 300, between Structures 93 and 94.

The line would be built using primarily single-pole, steel or concrete structures centered on a combination of existing 75-foot-wide and new 100-foot-wide right of way.

TVA will hold an open house on Thursday, October 5, 2023, to provide information, answer questions and receive comments about the proposed transmission project.

The project is expected to be in service in spring 2026.  Construction is scheduled to begin in winter 2025.  (Dates are subject to change.  Unexpected issues may arise, resulting in the need to adjust the schedule.)

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.

Nettleton, Mississippi (Lee County)

Update – January 2024

TVA has identified the preferred location for transmission improvements that would provide power for growing load and increase power reliability in the Nettleton area of Lee County in Mississippi. 

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 proposed 7.21-mile line would begin at the Tupelo-Okolona 161-kilovolt Transmission Line north of Old Union Road and south of Coonewah Creek.  The line will extend primarily southeast, staying south of Coonewah Creek, and end at the upgraded 161-kilovolt Nettleton Substation on the north side of Will Robbins Highway in west Nettleton.

The route selected is Route 8 and consists of Segments 2, 4, 6, 10, 12, 13, 19, 20, and 21 as presented at the open house held October 5, 2023, and online at the virtual open house held from October 5 through November 6, 2023.

The new line will be built using primarily steel or concrete, single-pole structures centered on a combination of existing 75-foot-wide and new 100-foot wide right of way.

  • Surveys of the right of way are scheduled to begin in spring 2024.
  • Easement purchases are scheduled to begin in summer 2025.
  • Construction is scheduled to begin in winter 2025-2026.
  • The line is scheduled to be in service in spring 2026.

The National Environmental Policy Act review is pending.

Background

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Nettleton area of Lee County in Mississippi.

Tombigbee Electric Power Association (TEPA) is planning to upgrade their Nettleton, Mississippi 46-kilovolt Substation to 161-kilovolt operation by April 2026.  TVA’s Tupelo-Okolona 161-kilovolt Transmission Line serves the North Shannon 161-kilovolt Substation area.  Presently, TEPA’s Nettleton, Shannon, and Laney Road 46-kilovolt Substations are all fed from a single, 10.2-mile feeder line out of their North Shannon 161-kilovolt Substation.  TEPA is experiencing reliability and capacity issues in the southern part of their service territory.  Capacity is exceeded in extreme peak conditions, and area growth will contribute to these issues.

TEPA’s upgrade of their Nettleton 46-kilovolt Substation to 161-kilovolt operation would be the second step of the solution to these issues. This would allow TEPA to improve flexibility and reliability on their system.  In a separate project and as the first step of TEPA’s solution to these issues, TEPA will also upgrade their Shannon 46-kilovolt Substation to 161-kilovolt operation in spring 2025.
