Infravision deploys drone stringing on Entergy’s 150-mile Amite South project

Infravision has deployed its drone-stringing system with Utility Lines Construction Services on Entergy’s Amite South Reliability Project in Louisiana. The work supports new 230 kV and 500 kV transmission lines extending more than 150 miles from Plaquemine to Westwego across farmland, marshland and difficult crossings.

The system installs an initial pulling line through blocks on transmission structures, allowing construction crews to pull subsequent lines and conductor. Entergy construction supervisors reported in field interviews that the method reduced rope-installation time by about 75% on some sections, from roughly seven days to a day and a half. That result is project-specific and not a guaranteed portfolio-wide productivity rate.

Brett Crochet, director of safety operations at ULCS, tied the deployment to reducing worker exposure. Chris Gremillion, Entergy’s vice president of project delivery for capital projects, said it is the first time the utility has integrated the technology into transmission construction. Matt Jones, Infravision’s chief commercial officer, described the work as the company’s largest U.S. project to date.

The deployment is ongoing, but the announcement does not provide an energization date, total project cost or open procurement. For utilities and transmission contractors, the milestone provides current operating evidence for drone-enabled stringing on a major U.S. build rather than a general technology demonstration.
