Project Details

HVdc - Safe, Reliable, Time-tested Technology
  • Buried cable avoids the visual impacts of overhead transmission projects by installing them out of sight — either underwater or underground.
  • HVdc current is very "controllable" and, unlike Alternating Current (AC), does not have a maximum distance thus making it well suited for a project of this length.
  • HVdc submarine cables have been in use all over the world for more than 60 years with projects in the U.S., Europe, and the South Pacific. Working examples include:

    • The Cross Sound project from Shoreham, Long Island to New Haven Connecticut.
    • The Neptune Project from Sayreville, New Jersey to New Cassel in the Nassau County New York.
    • The Trans-Bay HVdc cable project under construction in California connecting Pittsburg in East Bay to San Francisco.
    • A large number of working HVdc submarine cables transporting power between Europe and Scandinavia, between the UK and France, between the islands of New Zealand, and between Italy and Greece, just to name a few projects.
