Entergy Louisiana and Cleco have started construction on a new storm-hardened transmission line in order to enhance power supply network in Southeast Louisiana, US.
The scope of the project will include the construction of a 36-mile line that stretches from Gray to Patterson on steel structures, which can withstand winds of up to 150mph.
Entergy Louisiana will construct 24 miles of the new 230kV transmission line and additional related work with an investment of nearly $65m. Cleco will construct 12 miles of the line that will entail an investment of $48m.
Entergy Louisiana is constructing its portion of the line from its Terrebonne substation near Gray to a point at Bayou Boeuf near Amelia where it will interconnect with Cleco’s line.
Cleco will build its line between the interconnection and its Bayou Vista substation near Patterson.
The project will feature 235 steel transmission structures, which range in height from 80 to 115ft and will be supported on one-piece steel foundations weighing as much as 20 tonnes.
Entergy Louisiana regional director of customer service Melonie Stewart said: “This project is a great example of two utilities working together to benefit customers of both companies.
“It’s part of Entergy Louisiana’s commitment to invest in upgrading our power grid to better serve our customers.”
The final segments of the project are expected to be completed by fall 2018.
