The new standard for moderate wind conditions Siemens Wind Turbine SWT-2.3-101 www.siemens.com/wind Answers for energy.

Siemens has the right turbines for all wind conditions High Turbulence SWT-2.3-93 Low SWT-2.3-82 SWT-2.3-101 Wind Speed High Your trusted partner Siemens has been a major driver of innovation in the wind power industry since the early 1980s when wind turbine technology was still in its infancy. Technology has changed with the times, but Siemens’ commitment to providing its customers with proven wind turbine solutions remains the same. The combination of robust and reliable turbines, highly efficient solutions for power transmission and distribution and a deep understanding of the entire energy...

Superior performance gives higher yields Optimum energy at moderate wind conditions Harvesting more energy The SWT-2.3-101 wind turbine is designed to increase the energy returns from sites with moderate wind conditions. Advanced blade technology also allows for quieter operation. The B49 blade with a rotor diameter of 101 meters and pitch regulation optimizes power output, and increases control over the energy output. High availability Currently, the Siemens fleet of 2.3-MW wind turbines sets the industry standard for availability. The SWT-2.3-101 will build on the reputation for reliability...

No compromise on reliability SWT-2.3-101: Newest member of the extremely ­ reliable product family Designed for life Siemens turbines are designed to last. The robust design of the SWT-2.3-101 allows for trouble-free output throughout the complete lifecycle of the turbine. The blades are made of fiberglass-reinforced epoxy in S ­ iemens’ proprietary IntegralBlade® manufacturing process. The blades are cast in one piece in a closed process, which eliminates the traditional weaknesses found at glue joints in other manufacturers’ blades. Like the turbine itself, the blades are designed to last....
