By June this year there were 485 Enercon wind turbines in operation representing 125 MW, according to the company. Currently, 2 MW of wind capacity is leaving the Aurich works each week so that in the second half of this year alone around 130 E-40 machines will go in the ground, says Enercon. As well as opening marketing offices in the USA and UK, "Further offices will open in other parts of the world, " states the company.
Tacke's prototype TW 300 kW turbine is to be installed at Kaiser-Wilhem-Koog in September with three other 300 kW turbines to follow before the end of the year. One of these will be installed on the island of Rügen, the other two in inland North Rhine Westfalia. Series production will begin during 1995. Tacke says the 300 kW will supply the need in Germany for wind turbines smaller than the state-of-the-art 500/600 kW machines. This need exists where grid capacity is limited, where permitted noise emissions pose a limit on size or where potential operators have a small budget. With a view to the export market, the external dimensions of the 300 kW have also been determined by the need for container transport. Developing countries with less well developed infrastructures prefer smaller turbines, too. "The 300 kW will supply a niche market," says Tacke's Rainer Fiedler. "It is unlikely to reach the same sales volume as our 600 kW machine."
