Cable fault causes Lillgrund shutdown

110MW development expected to remain offline for several days

Vattenfall's Lillgrund offshore wind farm has been offline this week, due to a cable fault. The company has launched an investigation into the causes of the failure. Cameras are being deployed, but the 110MW development is not expected to be back online this week.

Lillgrund is located in Öresund, the strait between Denmark and Sweden. It is Sweden's largest offshore wind farm and came online in December 2007. It comprises 48 Siemens SWT-2.3-93 turbines.

In a Vattenfall document detailing the installation work, the company said it had experienced problems with the cabling, especially the export cable.
