The nacelle of the Nordex 2.5 MW N80 prototype wind turbine, targeted for offshore use, is to be displayed at this month's Husum wind energy conference and exhibition. Development costs are estimated at over DEM 20 million, says Hans Fechner of German Balcke-Dürr, which owns 75% of Nordex. Of this, Nordex is providing between DEM 5 million and 10 million. The turbine will have a new gear box developed by Flender, a new generator from Loher and new process controls from Babcock Prozessautomation. All three companies, like Nordex, are subsidiaries of the giant Babcock Borsig group. The first prototype will be installed at the Grevenbroich Wind Energy Testfield in North Rhine Westphalia (NRW) in December or January and series production is to begin at the end of 2000, says Nordex's Jürgen Millhoff. Testing at Grevenbroich was a condition of the development support from the NRW government.
