The developer took the decision in 2008 to take control of its turbine supply and develop its own 3MW turbine and it has now revealed images of the turbine in place in Germany.

The machine features a newly developed 690V outer-rotor air-cooled generator, with a six-metre outer diameter. It comes with a fully integrated bearing assembly, incorporating two taper-roller bearings. (cont).

The turbine for IEC class III sites features a 116-metre rotor diameter and a direct drive permanent magnet direct drive generator.

The head mass is about 200 tonnes. It can be installed with a 92-metre hub height tubular steel tower or two different hybrid concrete-steel towers of 122-metre and 142-metre hub heights.

A sister model for IEC class II sites, with a rotor diameter of around 110 metres, is in development.

Prokon's decision to develop its own turbine stemmed from its wish to gain reliable, low-maintenance wind technology and greater independence from market fluctuations when planning new wind farms.

Albrecht Schöttle, head of Prokon's turbine development and production, cited his company's slogan 'All from one hand' signalling a strong drive to be as independent as possible.

Serial production will be ramped up from 2014, for projects in Germany, Poland and Finland.
