Dutch-German grid operator TenneT has awarded a contract to the Italian cable manufacturer Prysmian for the 864MW SylWin1 project that will link offshore wind farms in the North Sea to mainland Germany.

Under the connection contract, valued at approximately EUR250m ($342.6), Prysmian will provide supply, installation and commissioning of submarine and land cable connections as part of a larger contract awarded to the consortium of Prysmian and Siemens Energy.

Siemens will deliver the Voltage Sourced Converter system, with a rating of 864MW.

The turnkey connection will link the DanTysk offshore wind park, located about 160km offshore, to the mainland with the purpose of transmitting power from renewable source into the German Grid.

The SylWin1 project will use extruded HVDC cable technology from Prysmian together with Siemens HVDC Plus converter technology at the offshore platform and onshore stations.

The cables and accessories will be manufactured from 2012 onwards at Prysmian’s European HV factories.

Installation activities will commence in 2012 and continue into 2013, and the commencement of commercial operation of the HVDC link is planned for 2014.
