348MW Baltic Sea project wins preliminary approval

Alstom 6MW turbines listed in project plan

Arcadis Ost 1 offshore wind farm has been granted preliminary approval by regulators. A 348MW project featuring Alstom 6MW turbines is envisaged, with construction due to begin in mid-2016.

Approval has been granted by the German state of Mecklenburg-Vorpommern’s energy ministry, allowing the installation of 58 turbines and an offshore transformer station as well as up to three additional ‘test’ turbines.

Arcadis Ost 1 is to be built within a 30km² site in the Baltic Sea, north-east of the island of Rügen, in water depths of 41-46m. The wind farm will be connected to the onshore grid via an AC cable that will feed into 50Hertz’s Lüdershagen transformer station.

Alstom Haliade 150 6MW turbines are listed in the project design submitted to authorities, although this does not bind the project developer to installing the turbine model.

Until 2006, Arcadis Ost 1 was known as the Ventotec Ost 1 project. Project developer Arcadis Deutschland sold an initial 50% stake in the project in 2008 to WV Energie, a conglomerate of German municipal energy utilities. Since then, it has sold the remaining 50%, which is now shared by Nordex (just under 39%) and the enterprise arm of the Austrian city of Innsbruck (11.1%).

The engineering company Arcadis remains involved as project coordinator and engineer, while the project's development company is now known as KNK Wind.
