Enercon E-115 wind turbine prototype suitable for inland apps
By Anthony Capkun
December 17, 2013 – Enercon says it has just finished installing its new Wind Class IIA prototype wind turbine in northern Germany; perched on a precast concrete tower at a hub height of 135 m, it is also available with towers ranging from 92 m to 149 m (hub height).
Due to an optimized blade design and a rotor diameter of 115 m, Enercon says the E-115 generates high yield even in the partial load range, making the new series a “profitable choice” for inland sites with slightly less wind. At a typical inland site with average wind speeds of 6.5 m/s at 149 m hub height, the E-115 can generate an annual output of roughly 9.3 million kWh, explains the company, which is an increase of 14% compared to the E-101.
