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 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 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

• 1,500 MW and +-500 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
