Evolved technology for best results

To reach increased energy production and deliver an industry-leading capacity factor, we have refined key features of our geared onshore wind turbines – the SWT-2.3-120 stands as the pinnacle of this refinement. The SWT-2.3-120 is a proven onshore product, tailored to medium to low wind sites, which offers you a safe investment with excellent returns for years to come.

Longer blades and internal refinements for increased capacity factor

When choosing the SWT-2.3-120, you choose the high performer among the geared onshore wind turbines. Based on its tried and tested predecessors, the SWT-2.3-120 incorporates a variety of innovative technologies that have been scaled and streamlined to deliver an industry-leading capacity factor. Starting with the blades: the 120-meter rotor with 59-meter aeroelastically tailored blades allows for enhanced energy capture. With a swept area of 11,300 m2 this turbine is designed to help you get the most out of your medium to low wind site. Compared to the B53 blade, the B59’s efficiency allows it to extract more kinetic energy out of the wind along the entire length of the blade. For increased performance, the SWT-2.3-120 blade uses Vortex generators on the entire length and has optimized cross-sections design.

 

Moreover, you can find several highlights in the internal system. For maximum reliability, the efficient cooling system is supported by open-air flow through the robust steel canopy. The tried and tested gearbox comes with a second planetary stage and one helical, for increased capacity in comparison to gearboxes that have only one planetary

stage.

Special features for added benefits

And there are even more ways to get the most out of your turbine. Despite its size and high performance, the SWT-2.3-120 is the quietest of the onshore geared wind turbines: at setting -2 dB (105 dB), it emits less noise and has higher yield than the SWT-2.3-108 in standard setting (107 dB) at wind speeds of up to 8.5 m/s. Grid services like Inertia Response or Weak Grid option enhance grid stability and enable compliance while environmental agility features, like different weather packages or Bat Function, let this turbine adapt to most outdoor conditions.
