TVA takes comment on power line to planned ‘Megasite’ in Tennessee

The Tennessee Valley Authority is taking comment until Dec. 28 on a draft environmental assessment (EA) on its proposal to construct a transmission line loop to provide a power supply to serve the Tennessee-owned Memphis Regional Megasite located in Haywood County, Tennessee, on the Haywood-Fayette County line.

The state of Tennessee requested that TVA plan for and provide a power supply to the state-owned Megasite that would facilitate the future development of that site of industrial facilities. At this time, the state has not identified any tenants that would occupy the Megasite. As such, TVA proposes to site and plan for routes capable of supporting both a 6.5-mile 161-kV transmission line and a 3.4-mile 500-kV transmission line. Once the state has identified an industrial tenant that would occupy the Megasite, TVA would only construct either a 161-kV or a 500-kV double-circuit loop transmission line. 

Both power supply options would run between an existing TVA transmission line and the Megasite. TVA proposes to purchase approximately 158 acres of right-of-way (ROW) easements that provide the necessary rights to construct, operate, and maintain the proposed line route.  These easements would accommodate various widths to allow TVA the flexibility to provide the voltage needed at the Megasite.

The current electric supply available in the vicinity of the Megasite is not capable of supporting a large industrial load. To meet the foreseeable power demand for an industrial tenant to locate at the site, TVA would need to provide new electric service to the area.
