New 161-kV Transmission Line Tap to Spencer Substation and 46-kV Transmission Line Retirement

Van Buren and Warren Counties, Tennessee

On February 18, 2016, the Tennessee Valley Authority (TVA) issued an environmental assessment and finding of no significant impact for its proposal to construct, operate, and maintain a 161-kilovolt (kV) transmission line in Van Buren County, Tennessee. This new transmission line would supply electric power to the upgraded Spencer 161-kV Substation, which is being constructed by Caney Fork Electric Cooperative (CFEC), a local distributor of TVA power. CFEC plans to upgrade the existing 46-kV substation to a 161-kV substation and has requested that TVA provide a new 161-kV delivery point to the substation. The new transmission line would connect the upgraded 161-kV substation to TVA’s existing Watts Bar Hydro Plant–Great Falls Hydro Plant 161-kV Transmission Line.

The transmission line would be built on 4.6 miles of 100-foot-wide right-of-way (ROW) and would occupy approximately 57 acres of new ROW. The proposal also includes installation of three switch structures and one permanent access road. After the new facilities are in service, TVA would retire and remove their existing 18.5 mile Great Falls Hydro Plant-Spencer 46-kV Transmission Line and associated equipment in the Great Falls Hydro Plant 46-kV Switchyard. TVA would update displays at its control centers in Chattanooga to indicate the status of the new and removed facilities.

Additional information on the project is available including background information, maps, and a project schedule.
