The tallest onshore wind turbine yet installed, with a 164-meter (538 feet) hub height, has produced over 9 GWh in its first year of operation. This output from the Nordex N131/3300 unit at the Hausbay-Bickenbach site in Germany was achieved against the backdrop of an average wind speed of 6.1 m/s.
The turbine's overall height approaches 230 meters (755 feet), enabling it to harness higher wind yield layers of air where there is less turbulence and to increase annual power output. Generating performance data confirms that powerful turbines with at least a 3 MW capacity, large rotor sweep and high towers are suited for efficient operation in regions with low average wind speeds.
The N131/3300 also has an advantage in terms of sound emissions. The guaranteed sound power level for the turbine is a low 104.5 dB(A). Measurements on the N131/3300 installed in the Krampfer wind farm in Mecklenburg-West Pomerania at the end of 2015 showed a sound power level of 104.1 dB(A).
Plans call for installing two more such wind turbines at the Hausbay-Bickenbach system operated by Kreuzberger & Spengler Regenerative Energie.
