The rotating blades of a wind turbine, in combination with the sun, can cast a moving shadow on their surroundings, which is referred to as shadow flicker. Wind Minds prepares reports about the shadow flicker caused by wind turbines and how this affects local houses. To that end, we use WindPRO, GIS and data from the national met office.
There are various possibilities that are suitable for the moment and depth of the request. This bandwidth runs from:
- A general exploratory analysis based on rules of thumb that are based on distances and direction in relation to houses, and wind turbine size. This may serve to substantiate a feasibility study or plan EIA;
- A comprehensive shadow flicker study based on model calculations (WindPRO), which may also deal with aspects such as calendar and weather conditions cumulative effects and mitigating measures. This may serve to substantiate an EIA, a zoning plan or permit application.
Wind Minds has prepared shadow flicker studies for more than 200 projects. As we have such an in-depth knowledge of the procedures, we ensure that the shadow flicker reports are in line with the preconditions set out by the competent authorities.
