Red Hills-Kosciusko 161-kV Transmission Line

Choctaw, Attala, and Winston Counties, Mississippi

On January 25, 2017, Tennessee Valley Authority (TVA) issued an environmental assessment (EA) and finding of no significant impact (FONSI) for its proposal to construct, operate, and maintain an approximate 43-mile transmission line crossing through portions of Choctaw, Attala, and Winston counties, Mississippi. The transmission line connects the Central Electric Power Association’s (Central EPA) upgraded Kosciusko 161-kilovolt (kV) Substation in Kosciusko to TVA’s existing Red Hills 161-kV Substation in Ackerman. The purpose of this undertaking is to improve the reliability of the electrical power system in the area by providing an additional source of power to the upgraded substation to address the voltage and reliability problems within Central EPA’s service area.

TVA would purchase approximately 524 acres of right-of-way (ROW) easements that provide the necessary rights to construct, operate, and maintain the proposed transmission line route. The new transmission line would be constructed using single and double steel-pole structures.

Additionally, TVA would install a second bus with associated metering, communication, and protective equipment at its Red Hills 161-kV Substation and provide metering equipment for Central EPA to install at its upgraded Kosciusko 161-kV Substation. New fiber optic ground wire would also install on the new transmission line to facilitate communications with the TVA network. The TVA map board displays would be updated to reflect this work. The scheduled in-service date for this project is October 2018.

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