The prototype was installed in northern Germany on a135-metre-high concrete tower, and will be available for tower heights of 92 to149 metres.

The E-115/3MW at a typical inland location with an averagewind speed of 6.5 metres per second at a tower height of 149 metres harvests9.3 million kilowatt hours of electricity a year, Enercon says. That is 14%more energy than Enercon’s E-101 turbine can produce at the same location.
