Columbia, Tennessee (Fiberon)

Proposed Transmission Project

Update July 2023

TVA is considering improvements to its transmission system that would provide power for growing industrial load and increase power reliability in the Columbia area of Maury County in Tennessee.

Fiberon will establish a manufacturing and distribution facility in Columbia, Tennessee, potentially creating over 300 new jobs over the next several years. The new facility will be located on Oakland Parkway northwest of State Highway 43 in west Columbia, and its operations will require a 161-kilovolt substation.

Columbia Power and Water Systems (CPWS) will build a 161-kilovolt substation at the Fiberon facility. TVA proposes to build a transmission line from our existing Maury-Mt. Pleasant 161-kilovolt Transmission Line to our existing West Columbia-Mt. Pleasant 46-kilovolt Transmission Line and then to the new Fiberon Substation.

In addition to this work, TVA would also install two switches on the Maury-Mt. Pleasant 161-kilovolt Transmission Line - one switch on each side of where the new line to Fiberon would begin.

The new line and rebuild/reroute portions would be built using primarily single-pole and H‑frame, single- and double-circuit, steel structures on existing and new 100-foot-wide right of way. The scheduled completion date for this project is fall 2025.

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.
