Experimental Validation of a Ducted Wind Turbine Design Strategy
This potential increase in power generation has continued to drive DWT research, however no commercial design has been 15 able to realize these augmentation factors and no commercially viable DWT has been successful.

Fundamentals of Wind Turbines | Wind Systems Magazine
At the rated output wind speed, the turbine produces its peak power (its rated power). At the cut-out wind speed, the turbine must be stopped to prevent damage. A typical power profile for wind speed is shown in Figure 2. In addition to an operating range, an installed turbine has a capacity factor that reflects its actual power generation.
