W’wave® Windwave Optimizes Wind to produce more competitive wind energy
INTRODUCTION to our TECHNOLOGY
Until today, wind conditions (wind speed, turbulence, wind shear) have been considered technical parameters that cannot be changed voluntarily in a wind farm. Wind developers need to measure it and they have to “live” with what they have.
What if we were able to improve artificially such wind conditions? We might see a considerable improvement considering wind power increases with the third power of the wind speed:
See Computational Fluid Dynamics (CFD) graphs below.
Colormaps indicate increase in wind speed through the turbine’s rotor thanks to the Concentrator effect.
<- Wind Speed profile Without WindWave
Wind turbines harvest kinetic energy from wind. Wind speed (and wind energy) typically grows with height (wind shear)
Wind Speed profile With WindWave ->
The WindWave enables a wind speed increase in the wind rotor area, shifting kinetic energy to the rotor area, where the wind turbine can harvest it.
Impact on the Wind Farm’s Wind Speed Frequency Weibull Curve or the Wind Turbine’s Power Curve.
W’wave improves the wind’s Weibull curve of the wind farm, so that the turbine can extract more energy from the site according to its power curve.
Or, seen from another perspective, W’wave improves the power curve of the turbine under the original wind’s Weibull curve of the wind farm.
Steel sheet piles are long structural sections with a vertical interlocking system that create a continuous wall. Steel sheet piles are constraint on having suitable soil characteristics. It provides a simple installation process, a minimal use of land, and a very short and traceable bill-of-materials with reusage and recycling possibilities.
The King Post design involves the construction of a wall by combining H-beams as columns and struts that sustain infill components. The columns and struts are anchored either directly in the ground through hammering or vibration or through a concrete foundation. The advantage of this design is its universality, not depending on specific soil conditions.
Wakes are responsible for severe wind speed reduction and turbulence increase that forces wind farm designers to space wind turbines considerably.
With our Concentrators the rows of a wind farm that are most affected by wakes can become very productive even at closer distances from the previous row, which enables to reduce the turbine-spacing constraints for wind farm designers.

How much can W’wave® Concentrators increase wind production?
- Production increase from W’wave® Concentrators can attain more than 35% of the original turbine production.
- Levelized cost of energy of the extra energy produced by our Concentrators can go lower than 20 $/MWh.
Investment payback period can go as low as 2 years.
It depends on many factors: The specific Concentrator design parameters (height, length and relative position to the wind turbine), the wind turbine characteristics (nominal power, rotor size, hub height) and the site characteristics (orography & layout).
