    Evolving technology for low wind onshore

    Low wind sites don’t have to mean lower return on investment. The SWT-3.15-142 secures your investment by combining new and proven technology for a groundbreaking onshore innovation.  


    The SWT-3.15-142 is a low noise turbine, based on the tried and tested technology of the existing Siemens Onshore Direct Drive portfolio. Using the same proven components and electrical systems assures reliability and performance. The blades of the SWT-3.15-142 feature hybrid carbon technology, designed in collaboration with LM Wind Power to produce an unparalleled blade design for targeting low wind sites.


    Other innovations include its direct cooling system for increased performance and reliability, and its noise control strategies, which allow noise-reduced operation depending on tower configuration and site-specific needs.


    Additionally, features such as the real-time Power Optimization add a new level of performance flexibility. Through this feature the SICS controller works together with the generator to readjust performance depending on the ambient environment, for continuous output. This means that even in the lowest of wind conditions you have an investment you can feel secure in.
