Memphis Regional Megasite Power Supply

Fayette and Haywood Counties, Tennessee

The Tennessee Valley Authority (TVA) is inviting public comment on the draft Supplemental Environmental Assessment (SEA) associated with the proposed Memphis Regional Megasite Power Supply Project. The draft SEA is available for comment until May 26, 2022.

An integral part of TVA’s mission is to provide power to local power companies (LPC) serving the 10 million people in parts of Tennessee and six surrounding states and to promote economic development within the TVA service area. TVA provides financial assistance in the form of incentives (credits and grants) to help bring to market new/improved sites and facilities within the TVA power service area and position communities to compete successfully for new jobs and capital investment. 

The State of Tennessee’s (State) 4,100-acre Megasite is in the Stanton, Tennessee area of Fayette and Haywood counties between Memphis and Jackson. In February 2016, at the request of the State, TVA completed the Memphis Regional Megasite Power Supply Environmental Assessment (EA) and Finding of No Significant Impact (FONSI). The EA analyzed potential transmission line routes capable of supporting a 161-kilovolt (-kV) transmission line and/or a 500-kV transmission line in preparation of ensuring the Megasite as well as the surrounding area including Stanton had a reliable power supply after the State of Tennessee’s Memphis Regional Megasite was developed. By planning for both potential voltages the normal process time for siting, constructing, and placing a transmission line into operation would be reduced allowing the State to attract potential industrial tenants ready to find placement for their operations.

Following the February 2016 FONSI, TVA then purchased 158 acres of right-of-way easements with the future intent of constructing, operating, and maintaining either a 161-kV or a 500-kV double-circuit loop transmission line. These easements would accommodate various widths to allow TVA the flexibility to provide the voltage needed at the Megasite.

In September 2021, the Ford Motor Company (Ford) announced plans to locate an electric vehicle and battery plant manufacturing facility (“BlueOval City”) on roughly 1,800 acres of the Memphis Regional Megasite (“Megasite”).  To support the new BlueOval City facility, Southwest Tennessee Electric Membership Corporation, an LPC and distributor of TVA power, plans to construct the BlueOval City 161-kV Substation on the Megasite property.

As previously described in the completed 2016 EA, TVA proposes to provide power to the Megasite area, including STEMC’s new substation, with the construction, operation, and maintenance of a 161-kV transmission line and a 500-kV transmission line. In addition, TVA proposes the construction of a new 500-kV substation on an approximate 67-acre parcel and two new 161-kV single-circuit transmission lines, all of which would be located on the Megasite property.
