MasTec Utility Services delivered comprehensive construction services supporting one of the nation’s largest offshore wind developments. The project involved installing more than four miles of underground 230kV XLPE duct bank infrastructure to connect energy from offshore turbines to the onshore grid.

Our team handled all aspects of trench excavation, splicing vault and transition bay installation, dewatering, and precision backfilling using both concrete and fluid thermal materials. With expertise in complex underground systems, heavy civil construction, and power delivery, MasTec ensured safe and reliable cable installation, as well as the seamless integration of offshore and onshore systems— strengthening the backbone of America’s clean-energy future.
