ENERCON has just finished installing the new Wind Class IIA machine in northern Germany and launched operations according to schedule.
The prototype is perched on a precast concrete tower at a hub height of 135 metres, but is also available with towers ranging from 92 to 149 metres (hub height). Thanks to its performance-optimized blade design and a rotor diameter of 115 metres, the E-115 generates high yield even in the partial load range making the new series a profitable choice also for inland sites with slightly less wind.
This new turbine type is a great addition to ENERCON‘s megawatt class models where, up until now, the top selling product was the E-101/3 MW machine with a rotor diameter of 101 metres. «The demand for this category of wind turbine is high. And customers now have yet another state-of-the-art turbine to choose from featuring technical innovations such as the divided rotor blade concept for optimised logistics,» says ENERCON Sales Director Stefan Lütkemeyer.
At a typical inland site with average wind speeds of 6.5 m/s at 149 metres hub height, the E-115 can generate an annual output of roughly 9.3 million kilowatt hours - an increase of 14 percent compared to the E-101. The E-115 will be available in series as of mid-2014.
