MISSISSIPPI — A major transmission upgrade worth $37 million in Warren County has been completed.

Entergy on July 21 said that Entergy Mississippi has completed a $37 million transmission upgrade that will improve service reliability to customers in the Flowers area of Warren County, Mississippi, with the project involving the installation of transmission breakers on the Beech Grove-Yazoo City-North Vicksburg 115-kV circuit.

Work on the project, which is now in service, began in November 2020.  The company said that the project included:

• Building new and rebuilding portions of transmission lines using steel structures, upgraded conductor, and fiber communications
• Building new and rebuilding portions of distribution lines using standard structures and upgraded conductor
• Expanding capacity at the Flowers substation from 8 MW to 50 MW and upgrading it, including hardening it against animal intrusions
• Rebuilding the river crossing at Big Black River

The transmission circuit serves about 4,000 Warren County customers along 58 miles of transmission line, the company said, adding that those customers include seven companies in the Ceres Industrial Park that employ about 1,000 people.

“Between 2018 and 2020, Entergy Mississippi placed more than $416 million in new transmission capital projects in service. In 2021, we plan to invest $120 million to continue to upgrade and modernize our transmission system,” said Haley Fisackerly, Entergy Mississippi president and CEO, in his statement.

The company noted that the Flowers project complements another major transmission project, the $31 million Mill Street substation, which went into service in March and provides a new source into the city of Jackson.

The upgrade will greatly improve service reliability for final customers.
