The prototype of the NEG Micon 2 MW turbine (1024 x 768 pixels, 132K JPEG) was commissioned in August 1999. It has a 72 m (236 ft.) rotor diameter. In this case (Hagesholm, Denmark) it is mounted on a 68 m tower. In the background you see the foundations for two sister machines.The turbine is intended for offshore applications.

From the outside it resembles the 1500 kW NEG Micon machine so much, that you'd have to see the turbine in its stopped state (with the blades pitched out of the wind) in order to notice the difference: The rotor blades are pitchable, since the machine has active stall power control , whereas its 1500 kW cousin has passive stall power control.

The prototype of the Bonus 2 MW turbine (88 K) was commissioned in the fall of 1998. It has a 72 m (236 ft.) rotor diameter. In this case (Wilhelmshaven, Germany) it is mounted on a 60 m tower. The turbine is intended for offshore applications, and has Combi Stall® power control (Bonus trademark for active stall power control ). The machine resembles the Bonus 1 MW and 1.3 MW machines considerably.

The prototype of the Nordex 2,5 MW turbine (132 K) was commissioned in the spring of 2000. The rotor diameter of the wind turbine is 80 m. The image shows the prototype at Grevenbroich, Germany, which has a 80 m tower. The turbine has pitch power control.
