SWT - 2.3 - 113 Turning moderate wind into maximum results www.siemens.com/energy Answers for energy.

At the leading edge of evolution The new Siemens SWT-2.3-113 wind turbine is the ultimate choice for low to moderate wind conditions. The revolutionary direct drive generator and the new, optimized Quantum Blade are paired to extract as much energy as possible from the wind. Efficient. Quiet. Robust and reliable. The Siemens SWT-2.3-113 is the new benchmark wind turbine for low to medium wind speeds. As a result of more than 30 years of research and development, it is designed to harvest more energy out of moderate wind conditions than anyone thought possible. Unique aerodynamics The...

You cannot change the wind. It may be strong, it may be light. This leaves it up to us to extract as much energy as we can from it. Anne Schannong Vinther, Quality Engineer 3

Innovation for efficiency Siemens direct drive technology and the new Quantum Blade represent groundbreaking wind turbine design and technology. The result of these two key innovations is a turbine with maximum efficiency and reliability, which helps to enable a solid return on investment. Maximized performance with 50% fewer parts The Siemens direct drive design incorporates a permanent magnet generator with fewer moving parts than ever before. The simple permanent magnet design offers increased efficiency directly by minimizing energy losses and indirectly by reducing maintenance needs....

Lower noise With a low 105 dB noise level, the SWT-2.3-113 is one of the quietest wind turbines on the market. As a result, this turbine type has an extremely high ratio of energy output per noise affected area, resulting in fewer disturbances to people and wildlife. Superior grid compliance The Siemens NetConverter® is designed for maximum flexibility in the turbine’s response to voltage and frequency variations, fault ride-through capability and output adjustment. The advanced wind farm control system provides state-of-the-art fleet management. 5
