Entergy Mississippi, Inc., Florence-South Jackson, Mississippi, 115-kilovolt Transmission Line Upgrade

Hinds, Rankin, and Scott Counties, Mississippi

On November 12, 2009, TVA issued an environmental assessment and finding of no significant impact for its proposal to upgrade approximately 7.5 miles of an existing 115-kilovolt (kV) transmission line on the Entergy Mississippi, Inc. (EMI), transmission system in Hinds and Rankin counties, Mississippi. The upgrade is needed to support the transfer of 724 megawatts of electricity from the Ackerman (Suez Choctaw) generating facility to the TVA transmission system.

The upgraded transmission line would utilize mostly single-pole steel structures on existing 100-foot right-of-way occupying about 92 acres. Additionally, two switches would be replaced at EMI’s Morton 115-kV Substation in Scott County. TVA would provide the funds to EMI for these necessary upgrades.
