HVDC Light®

HVDC Light® is a state-of-the-art power system designed to transmit power underground and underwater, 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 Hitachi Energy, 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 8,000 MW and 800 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 Hitachi Energy
• Underground power links
• Providing shore power supplies to islands and offshore oil and gas platforms
• Connecting asynchronous grids
• City center in-feed

Product scope

• 8,000 MW and 800 kV

Why Hitachi Energy?

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