Siemens has installed a fourth offshore platform in the North Sea, completing an important stage for grid connections of sea-based wind farms.
This is the platform for the SylWin1 DC link, which is the most powerful of the four offshore wind power grid connections contracted to Siemens by the German-Dutch transmission grid operator TenneT between 2010 and 2011.
Only a few days prior to this, Siemens installed the third platform at sea for the HelWin2 grid connection. In all, Siemens is implementing five North Sea grid connection projects for TenneT. The first four grid connections, whose platforms have now been installed at sea, are scheduled to take up commercial operation successively between the second half of 2014 and the first half of 2015. The fifth grid connection, which was contracted earlier this year, is slated to go on-line in 2019.
“We have now erected four high-tech platforms for TenneT in the North Sea. We succeeded in completing the first installation last year and erected the other three platforms in quick succession this year – an ambitious task as far as technology and logistics go. Once they have been commissioned, these grid connections will supply electricity from offshore wind power for around three million households,” stated Jan Mrosik, CEO of the Power Transmission and Smart Grid Divisions of Siemens AG.
