Being built by WPD offshore, the project is located within the 12-sea mile zone at the mouth of the Weser, about 40km northwest of Bremerhaven.
Under the contract, Senvion will deliver, install and commission 18 Senvion 6.2M126 turbines, each with 6.15MW capacity.
Scheduled to be completed in 2016, the Nordergründe offshore wind farm will generate electricity required for more than 70,000 households annually.
Senvion SE CEO Andreas Nauen said: "Thanks to the clear compensation provisions of the EEG (Renewable Energy Sources Act) our clients will be able to plan reliably, but the German offshore sector will soon need clear indicators for the years after 2019.
"The preparations for EEG 3.0 are the next step, and must start already this year."
Separately, Bilfinger Marine & Offshore Systems has also been awarded a contract by WPD for the installation of 19 steel foundations and transportation of 18 wind turbines to the installation site in support of the Nordergründe offshore wind project.
