High Voltage DC (HVDC) cables are an emerging energy transmission technology that provide a more efficient means of transmitting electricity over long distances than the more widely used AC cables.
Experts regard the roll out of HVDC cables as an essential component of many large scale renewable energy projects, as they will enable developers to transmit power efficiently from remote offshore wind farms and desert-based solar power plant to population centres.
The UK's National Grid has proposed that two HVDC cables be deployed to transfer power generated by Scottish wind farms to the South of England, while HVDC cables are likely to play a key role in the development of new renewable energy networks around the North Sea and Mediterranean.
