The first order under the agreement has already been placed by the developer. Senvion will supply a total of 21 turbines from its 3MW range across four of Prokon's projects totaling a combined 69MW.
The four projects will comprise one 3.2MW and five 3MW turbines, all with 122-metre rotors, eight 3.4MW turbines with 114-metre rotors and seven of Senvion's new 3.4MW turbine with 140-metre rotors.
Commissioning of the four projects is expected to begin this year, with the final project due online in 2018.
Energy cooperative Prokon currently operates 57 projects in Germany and Poland, with a combined 557MW capacity.
Prokon CEO Heiko Wuttke said: "The Prokon cooperative is active with its projects in regions with very different wind potentials, both in the north and in the interior of Germany. Therefore, it is important for us that our wind turbines meet all these different challenges."
In January 2014, Prokon filed for insolvency following the withdrawal of capital by a number of investors.
However, in July 2015, the creditors and shareholders decided to turn the company in to an energy cooperative, instead of accepting an all-cash bid from developer EnBW.
