Shadow Flicker

An assessment of the potential shadow flicker effects has been carried out as part of the application. ‘Shadow Flicker’ is the term used to describe the effect that occurs when the shadow of a wind turbine blade passing a small opening (window), briefly reduces the intensity of the light within the room, causing a flickering to be perceived. It only occurs under certain weather conditions, and for a limited number of hours at certain times of the year, when the turbine is in a specific orientation to the sun.

 

Any properties identified as being at risk of shadow flicker beyond the recognised limits will be protected through the turbines being programmed to be switched off at the appropriate time if sunlight is present.
