The approach taken to wind turbine development in the UK is to assess the potential impacts of proposals on a case by case basis. Such assessments will include, for example, possible impacts of noise and shadow flicker on dwellings in the vicinity of the proposed development, and will be informed by Government guidance.
An independent study commissioned by DECC and published in March 2011 showed that the Government’s current guidance on the ‘distance’ parameter used for the assessment of ‘shadow flicker’ is broadly consistent with that of different European countries.
In addition, DECC published an independent report in July 2011 which found that current Government guidance are appropriate for assessing the noise impacts from wind farms, and recommended that good practice advice should be produced to confirm, and where necessary, clarify the way the guidance should be implemented in practice. The Institute of Acoustics is taking forward work to develop such advice.
