The Arcadis Ost 1 project is located in the German section of the Baltic. The initial construction phase will seen 70 turbines installed in a water depth of around 40metres.
Construction on the project is expected to begin in 2014 and will use a new offshore turbine being developed by Nordex that is believed to be in the 5MW range.
The majority shareholder in the project is WV Energie, which is 50% owned by Wintershall. The remaining 50% is owned by around 200 utilities.
Speaking about the deal Nordex CEO Thomas Richerich said: "In Germany in particular, the targets defined in the government's climate policy can only be achieved by the greater construction of offshore wind farms.
"For this reason, a market segment comprising turbines with an installed capacity of over 5GW per annum will emerge over the next few years. Following preliminary test installations in the Baltic Sea, Arcadis Ost 1 will be our reference project in the offshore market."
