Siemens Gamesa’s next generation high capacity factor SG 4.4-164 wind turbine is a highly flexible and versatile turbine that has been developed based on the needs of those customers developing projects in the U.S. wind power market. The turbine has the right design profile to maximize revenues by harnessing the wind conditions most common in the U.S. and features a design lifetime longer than the industry standard.
Development of the SG 4.4-164 turbine represents Siemens Gamesa’s commitment to create value for our customers through the continuous development of technologies that improve performance, competitiveness, and quality excellence. The model leverages both established and updated platform design to minimize costs and streamline constructability.
The SG 4.4-164 incorporates a combination of a three-stage gearbox (two planetary stages and one parallel), and a doubly fed asynchronous generator. The high-performance passive cooler outside the nacelle and the cabinet’s improved ventilation ensures efficient thermal conditioning and performance at higher temperature sites.
