Incomparable robustness for best returns

To ensure a lifetime return on your investment, turbine technology has to meet your needs. For extreme wind conditions, the answer lies with the SWT-3.2-101 and SWT-3.4-101. By balancing innovation with proven technology, the SWT-3.2-101 and SWT-3.4-101 ensure that you receive these benefits.

The durable choice for high wind conditions

Simple, but innovative – a rare combination. But  Siemens direct drive onshore turbines were designed to incorporate this combination for your benefit. A straightforward wind turbine design reduces the number of rating and wear-prone components, for increased simplicity and improved efficiency – a must in harsh conditions. Higher towers significantly increase the energy output, while the 101-meter rotor – in comparison to the 108-meter rotor of the SWT-3.4-108 – makes more sites with height restrictions available for onshore investments.


The SWT-3.2-101 and SWT-3.4-101’s compact and light weight design has been engineered to meet even the most demanding transportation routes and is a major advantage for installation. With the increased availability and profitability of the direct drive technology, your investment is secure.

Taking one step further

The 3.4 MW turbines are uprates of the tried and tested 3.2 MW direct drive turbines and enable an increase in annual power output by up to 3%. This is possible because the increase of the electrical power via different small changes is able to achieve the higher rating. The rated rotor speed stays on the same level to keep the noise emissions low.
