Transmission Expansion and Innovation

ENTERGY CORP /DE/ · 2026-11-02 · Importance 46 · Surprise 24

Entergy has more than 1,000 miles of transmission lines planned, primarily in Louisiana and Texas, and 85% of the planned lines are 500-kV. About 70% of the investment is approved and roughly one-third of the line miles are under construction; management said the projects will support traditional industrial customers and data centers while also improving system efficiency and resilience. Entergy described design and construction innovations for difficult-to-access terrain, including drone-based line stringing and helicopter-assisted crossarm installation, to reduce construction time, labor needs, and injury risk. The company also signed firm natural-gas transportation agreements for 1.325 billion cubic feet per day, sufficient to supply ten new combined-cycle plants in Louisiana and support industrial growth.
