Improved grid reliability by HVDC Light®, values

Increased grid reliability byFast and accurate voltage control

Can not be overloaded

Black start capability

Short time to market by simplified permitting procedure

DC lines will never be subject to an unforeseen increase of power flow due to the outage of system components. Therefore it is not necessary to reserve capacity margins on DC lines in order to fulfil the (n-1) principle. DC links can rather be operated at their rated power, unless there are limitations inside the adjacent AC networks.

What can HVDC Light® do for you ?We can offer proven system with unique features

Environmentally adaptedSuperior grid reliability properties

Cost competitive particularly when all factors are considered, example

Undergrounding used to be 5 – 15 times more costly, with HVDC Light® relation could typically be 1 – 3 times

Suitable to meet new demands such as grid reliability and connection of wind farms. Offshore power supply has shown the example.
