German-Danish wind turbine maker Nordex is developing two new models-an 800 kW machine targeted for the export market and a 2.5 MW for use offshore. With both machines, Nordex aims to reduce specific generation costs to about DEM 1000/kW, compared with its DEM 1500/kW average today. In an apparent reference to competitor Enercon's turbines without gear boxes, such a reduction in generation costs is only possible with turbines using gear boxes, says Hans Fechner of German Balcke-Dürr, which owns 75% of Nordex.
With the new 800 kW unit, Nordex aims to reduce the dimensions and the nacelle weight, saving material and thus the installed cost. The machine is predicted to improve the German wind industry's chances on the export market. The 2.5 MW N80 machine will have a new gear box developed by Flender, a new generator from Loher and new process controls from Babcock Prozessautomation.
