GE - Model 1.85-82.5 - Wind Turbine
From General Electric - Wind Turbine
The GE 1.85-82.5 is the turbine of choice for IEC class II winds, and provides over 7% more AEP than the 1.6-82.5 at 8.5 m/s. The 1.85-82.5 turbine is available in tower heights of both 80 and 65 meters. These tower sizes both provide flexible options for Class II wind sites,as well as higher energy capture in a variety of challenging environments.
