Alstom upgraded its 3-MW onshore ECO 100 turbine to maximize available wind resources. Currently designed for medium (Class II-A) wind sites, the turbine now can handle medium and high winds (IEC Class II-A, and IS Class). The ECO 122 turbine, currently suitable for Class III sites, is being upgraded to handle medium and low winds (IEC Class III-A, and II B Class). The upgrade increases the net capacity factor to up to 48 percent for both turbines.
