HVDC Light

HVDC Light® is a state-of-the-art power system designed to transmit power underground and under water, also over long distances. It offers numerous environmental benefits, including “invisible” power lines, neutral electromagnetic fields, oil-free cables and compact converter stations.

HVDC Light® increases the reliability of power grids, and the technology extends the economical power range of HVDC transmission down to just a few tens of Megawatts (MW). In the upper range, the technology now reaches 1,500 MW and +-500 kV.

 It is quick to install and provides an alternative to conventional AC transmission systems and local generation.

Possible applications include:

  • Connecting wind farms to power grids
  • Underground power links
  • Providing shore power supplies to islands and offshore oil & gas platforms
  • Connecting asynchronous grids
  • City center infeed

Product scope

  • 1,500 MW and +-500 kV

Why ABB?

  • The HVDC Light® underground cable technology makes it easy to obtain permits for the new link
  • The superb controllability if the HVDC Light® also contributes to improve the voltage stability of the entire AC network
