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 14th Annual Underground Transmission Conference hosted by Eversource Energy will engage attendees in examples of recent underground projects as well as those challenges to take-on with operating existing systems. Replacement of cable types as well as restoration after leaks and developing plans for maintenance streamlining including leak detection are some of the additional topics discussed.

Learning Outcomes

  • Review Eversource Energy’s projects and their unique challenges and new installation methods
  • Detail American Electric Power’s lessons learned from projects across multiple states
  • Discuss National Grid’s strategies and methods used to engage stakeholders in the public engagement of underground projects
  • Highlight the challenges and installation methods considered by Eversource Energy for a submarine cable running across Little Bay
  • Delve into National Grid’s procedures and lessons learned from the response to leaks
  • Engage in a panel discussion of engineers and contractors on the challenges facing underground transmission
  • Review LADWP’s case study of the construction on their Sylmar ground return system-ocean electrode project
  • Discuss options for reconductoring of both HPFF and HPGF circuits
  • Expand on what to look for in construction/installation of underground transmission circuits as a utility staff person overseeing the project

Doug Foley, Vice President Electric Field Operations, Eversource Energy


9:00 – 10:00 a.m. :: Recent Experiences with New UG Transmission Technologies and Installation Methods

Eversource has a wide variety of UG transmission projects that are currently taking place or have recently taken place. These projects include installation of submarine cable, XLPE Cable, and HPFF Cable. Unique challenges have come up on all these projects and Eversource would like to discuss some of these challenges and new installation methods for completing these projects.

Mike Falco, Transmission Engineer, Eversource Energy

10:00 – 10:30 a.m. :: Networking Break


10:30 – 11:15 a.m. :: Challenges and Lesson Learned on Underground Circuits in Multi-States

American Electric Power has a variety of underground circuits throughout its multi-state territory and has faced varying challenges from them. This presentation will review those challenges and share detailed lessons that were learned from coordinating these multiple projects.

Jared T Jajack, Senior Transmission Engineer, American Electric Power


11:15 a.m. – 12:00 p.m. :: Public Engagement for Underground Transmission Projects

Underground transmission projects require a balance be struck between the need for additional energy development and landowner priorities, environmental impact considerations and regulatory compliance. A comprehensive strategic public engagement process is a key tenet to the success of a project.  Stakeholders must be engaged throughout the process, using a wide variety of communication and engagement techniques that are tailored to the needs of each stakeholder.  The strategies and methods they use to positively engage stakeholders, build trust with the community, and overcome project obstacles will be discussed.

Marc Lucas, Director of Major Permits and Stakeholder Management, National Grid

12:00 – 1:00 p.m. :: Group Luncheon


1:00 – 1:50 p.m. :: Installation of Submarine Cable Across Little Bay

This presentation will review the complex installation of this 115-kV submarine cable in the bay and which installation method would have the least disruption on area residents and properties, the lowest cost, as well as the shortest schedule, and would be the most appropriate method.

Joseph Sperry, P.E., Senior Engineer, Eversource Energy

Todd Goyette, Senior Project Engineer, POWER Engineers


1:50 – 2:40 p.m. Comparison of Response to Two High Pressure Cable Fluid Leaks

This presentation will delve into the details of National Grid’s response to two separate leak incidents. The procedures and results of each will be discussed and compared while looking overall at the lessons learned from the response to these leak situations.
