Vattenfall and Stadtwerke München (SWM) are constructing the Offshore Wind Farm DanTysk from 2012 on. Today, the two partners have secured a High Voltage Substation to be supplied by the consortium of Strukton Systems B.V. and Hollandia B.V.

The turnkey project involves the supply and installation of a 155/33 kV Offshore Substation to connect the 288 MW DanTysk Offshore Wind Farm, located in the German Exclusive Economic Zone in the North Sea, with the Sylwin HVDC cluster grid connection.

'This contract shows the high offshore ambition of Vattenfall and Stadtwerke München', says Claus Wattendrup, Commercial Project Director of DanTysk. 'Strukton and Hollandia have extensive experience in substation design and construction as well as offshore installation works and could prove to be most competitive in european-wide tender process. After having secured turbines and the substation now, we continue in negotiating inter-array-cabling and turbine foundations. The first turbines are planned to go into operation in 2013, the whole wind farm will be completed in winter 2013 /2014.'

DanTysk Offshore Wind GmbH is a joint venture between Vattenfall Europe Windkraft GmbH (51%) and Stadtwerke München GmbH (49%). Vattenfall will be responsible for the construction and operation of the wind farm. The installation of the substation is planned for 2012, commissioning is scheduled for 2013/2014. The North Sea wind farm will be situated roughly 70 kilometres to the west of the German island of Sylt. It will consist of 80 turbines (3.6 MW, 120m rotor) and with a total capacity of 288 megawatts (MW) produce renewable energy equivalent to the electricity consumption of 500,000 households, based on a German average electricity consumption of 2,500 kWh per home. The total investment is estimated to more than one billion Euros.
