The wind power facility M5000 has been developed by the Multibrid Entwicklungsgesellschaft mbH. The new concept for this facility comprises a robust single-stage epicyclic gear set, an air-cleaning and an overpressure system as well as a special permanent magnet generator.

The concept was primarily developed to meet the needs of offshore operation with a capacity of 5 megawatts. The first two prototypes of the M5000 were put into operation 2004 and 2006; in 2007 more units are to be completed. A variety of companies and institutes of the network WAB participated in the R&D projects.

The company WeserWind GmbH Offshore Construction Georgsmarienhütte has built a prototype of a tripod foundation for offshore-wind power facilities on shore. Offshore wind power facilities in water more than 25 metres deep need a solid foundation; the foundation built weights about 600 tons, is 30 metres tall and is located north to Bremerhaven. The main focus was to develop suitable production processes, in which a number of companies and institutes of the WAB network were involved in with R&D projects.

In the context of the project a facility for static and dynamic testing of rotor blades is being built at the moment. It is the first of its kind in Germany for rotor blades with up to 90 metres in length. The Frauenhofer IFAM Bremen, the Frauenhofer LBF Darmstadt, the Frauenhofer CWMT, and the competence group rotor blades, a workgroup of all manufacturers of rotor blades and wind power facility manufacturers, are involved. The centre will be finished by 2009.

The company Deutsche WindGuard GmbH developed a wind tunnel specifically suited for the needs of the wind sector. Wind top speeds of more than 250 kph are achieved, matching the actual top speeds of wind power facilities rotor blades. Acoustic optimization of the tunnel helps to examine and minimize the noise emission of wind power facilities. Sections of rotor blades and the air flow within and at miniature models of landscapes and buildings can be studied in the wind tunnel.

The company energy & meteo systems GmbH develops capacity assessment tools for operators of wind parks, energy net operators and energy suppliers. Meteorological data therefor are provided by the company meteocontrol. Inaccuracy of the tools predictions is at about six percent for the 24 hour forecasts.
