When you need more transmission capacity in challenging environments, we bring the experience and knowledge needed to complete your complex project.
Underground transmission line design is a highly specialized service used to meet unique siting and capacity challenges. We are one of the few firms to offer siting and routing studies, stakeholder management, civil design, electrical design, construction management and construction of underground systems. We provide innovative design-build and engineer-procure-construct (EPC) solutions to support underground transmission projects.
We’ve been at the forefront of this complex service, leading new developments and pioneering the installation of groundbreaking projects, such as the first and longest 500-kV underground solid di-electric transmission line in North America. We’ve chartered new territory as the engineer-of-record on many progressive underground transmission projects, including the first large-scale 345-kV cross-linked polyethylene (XLPE) project in the United States, and one of the longest successfully energized 345-kV XLPE systems in the country. While we have been involved in those large and complex projects, we are also here to assist with projects of all types and sizes. Whether it is a industrial application, an end-of-life asset replacement or an underground getaway out of a substation, we have done it. We are currently helping advance the development of offshore wind projects in North America.
As the North American representative to the CIGRE cable group dedicated to establishing cable testing and commissioning standards and active members and chairs of the IEEE Insulated Conductors Committee (ICC) working groups, we’re not just familiar with the latest standards — we’re working to establish them. Our engineers are at the forefront of the industry and bring that unique experience and perspective directly to you.
