The world's most remote offshore wind farm cluster is connected to the German grid by a 400 MW HVDC Light® transmission system.
The German utility
TenneT Offshore GmbH , formerly known as transpower stromübertragungs gmbh and E.ON Netz GmbH, awarded a contract to ABB to supply the power transmission that deliver power from the world’s most remote offshore wind farm into the German grid.
The BARD Offshore 1 wind farm is developed by BARD Engineering GmbH. It will consist of 80 wind generators of 5 MW located about 130 km from the coast in the North Sea. The generators feeds power into a 36 kV AC cable system which is transformed to 154 kV for the HVDC Light®offshore station. The receiving station is located at Diele, 75 km from the coast, where the power is injected into the German 380 kV grid.

The cables were laid underwater and underground, thus minimizing environmental impact. |
The BARD Offshore wind farm is scheduled to be in operation in 2012.
