Product Information

Higher returns, lower costs

Onshore, high wind conditions require a turbine solution that can meet a variety of needs without increasing energy costs. Ideal for such circumstances, the SWT-3.2-108 and SWT-3.4-108 were designed to go beyond your needs and offer the highest returns. 

Three turbine in a row

Superior design for superior performance

When winds are strong, but site conditions less complicated, you need a turbine that will bridge these factors. Presenting Siemens’ SWT-3.2-108 and SWT-3.4-108 direct drive onshore turbines, a superior combination of large rotor and robust design.


The B53 quantum blade of the 108-meter rotor was the first full-scale application of Siemens’ innovative aeroelastic blade design, which allows for a larger rotor diameter and higher energy output without increasing structural loads. Even more, the rotor’s weight did not increase in comparison to the B49 blade. As a result, the SWT-3.2-108 and SWT-3.4-108 turbine provides lower cost of energy at moderate to high wind conditions.

Making good things even better

The 3.4 MW turbines are uprates of the tried and tested 3.2 MW direct drive turbines. Small torque increase within the capability of the gearless generator and an optimized magnet composition boost the rated power. And thanks to the larger rotor, the SWT-3.4-108 delivers even more energy than the SWT-3.4-101 and is therefore the ideal choice when there are no height restrictions – ensuring that your turbine is always working at the optimum level for your benefit.
