Overhead line construction and stringing contractors

BOTTLENECK

Labor and equipment shortages constrain overhead line construction, and Quanta's record backlog shows why new qualified crews cannot scale quickly.

Field crews erect towers, string conductors and commission overhead lines. Labor and equipment shortages make this the bottleneck for grid expansion serving AI load growth. Quanta, Primoris and MYR Group hold record backlogs, with Quanta alone at $39.2bn.

Field construction crews performing tower erection, conductor stringing, hardware fitting and line commissioning; experiencing severe labour and equipment shortages.

What the evidence shows

Leaders for pullers, tensioners, and stringing units include Sherman Reilly, Hogg Davis, TSE International, and others.
