Anderson 500-kV Substation and Associated System Modifications

Anderson, Blount, Knox, and Roane Counties, Tennessee

On May 29, 2020, Tennessee Valley Authority (TVA) issued a final environmental assessment (EA) and finding of no significant impact (FONSI) for its proposal to construct a new 500-kV substation in Anderson County, Tennessee and to modify other transmission system assets which provide the bulk power supply to Knoxville and the surrounding areas. 

TVA plans to retire the Bull Run Fossil plant in 2023. To compensate for the loss of generation at TVA’s Bull Run Fossil plant, TVA’s Bulk Transmission System needs to be upgraded to ensure the electric load on the power grid is not disrupted and the surrounding area’s future and present power needs are met. The proposed Anderson 500-kV Substation would be constructed on TVA property located across the Clinch River from the Bull Run Fossil plant. 

Additional information on this project and the closing of the Bull Run Fossil Plant is available.
