The new 4.8MW wind turbine, GE's first onshore entry in the 4MW space, is equipped with 77-meter-long carbon blades, a 158 meter rotor and a range of tip heights up to 240 meters.

The combination of a larger rotor and tall towers enables the turbine to take advantage of higher wind speeds and produce more energy. The turbine meets a lower standard of noise emission levels, achieving a 104-dB level during normal operations. The newly-designed machine head reduces the needs for a larger crane while facilitating up-tower repairs and troubleshooting with its up-tower electrical system. The blades also feature one of the industry's smallest Bolt Circle Diameters, keeping manufacturing and logistical costs to a minimum.
