Southwest Louisiana Transmission Infrastructure Upgrade
With the completion of this nearly $100 million project, Entergy Louisiana customers in Southwest Louisiana are now being served by a stronger, more resilient grid.
The upgrade covered approximately 900 square miles, almost all of which is within Jefferson Davis Parish, and included the construction of new transmission lines as well as rebuilding many existing lines. Both the new and rebuilt sections of line use steel structures that can withstand winds of up to 140 miles per hour and employ reinforced high-voltage wire that will move power more reliably and efficiently. In total, approximately 58 miles of lines were added or upgraded. In addition, the project included the construction of a new substation located in Welsh, Louisiana. To ensure the reliability of the new and upgraded transmission lines, five substations were modified to replace equipment such as protective relays and circuit breakers.
