Design
GE’s 1.5-77 turbine has a 19% increase in swept area relative to the 1.5-70.5 resulting in greater Annual Energy Production (AEP). GE’s 1.5-77 Class I wind turbine has a 57.9% gross capacity factor at 10 m/s – a class leading performance.

GE’s new 1.5-77 (Class I) with Advanced Loads Control shares components with the 1.5-77 (Class II) and 1.6-82.5 creating one common 1.5 MW wind turbine series platform. This ensures consistent workhorse reliability, ease of maintenance planning and high commonality in spare parts.

Available in 65 and 80 meter heights, the towers are reinforced for use in seismic areas. The 1.5-77 turbine is designed for the most robust wind resource environments on the planet.

Focusing on performance, reliability, efficiency, and multi-generational product evolution, GE’s Class I 1.5-77 wind turbine continues to deliver wind product leadership. GE’s proprietary Advanced Loads Control system is designed to enable the 1.5–77 meter rotor wind turbine to meet design loads and related certification requirements for IEC Class I.
