Overview

Going underground with transmission has traditionally been a transmission owner’s last resort because the cost of underground transmission is many times the cost of overhead transmission and maintenance and repair has proved costly and difficult. However, advanced cable technologies have been developed, installation techniques have expanded in terms of options and efficiency while cost factors have improved giving transmission owners more realistic options. Operators and owners that have existing underground transmission know of some of the challenges they face efficiently operating underground systems regarding maintenance, repairs, leak detection and outage times.

 

This 15th annual underground transmission program will engage attendees in examples of recent underground projects from submarine applications to urban and suburban routing. Retrofitting of cable types as well the siting and routing of underground lines are some of the additional topics discussed.

Learning Outcomes

  • Discover what has been learned during the refurbishment of transmission feeder pipes using composite materials
  • Review design and installation considerations for urban locations and railroad crossings
  • Discuss a HPFF retrofit with XLPE cable of an existing submarine line
  • Discover how offshore wind projects provide unique challenges in the routing and siting of their submarine cables
  • Engage in a discussion on the challenges of siting new underground transmission lines in urban and suburban environments
  • Review the construction activities of this bi-directional direct current transmission system that connects the Pacific Northwest to the Southern California region
  • Engage in this panel discussion on challenges faced and successfully resolved in underground transmission projects

12:30 – 1:15 p.m. :: Group Luncheon


1:15 – 2:10 p.m. :: Lessons Learned in Successfully Siting UG Transmission in Urban & Suburban Settings

Successfully siting new underground transmission lines is a complex undertaking made more complex when located in urban and suburban environments. While constructing in densely developed areas may mean fewer natural resource impacts, it also may mean that communities zealously guard against impacts to those relatively scarce amenities. Further, the density of development and the resulting proximity of people to disruptive construction in their streets means greater scrutiny of impacts to the social environment and public health, including EMF. This presentation will focus on lessons learned from successfully navigating the regulatory and community demands that are present when proposing to construct an underground electric transmission project in urban and suburban settings.

Mark R. Rielly, Assistant General Counsel, National Grid USA
