Wind turbines in sunshine

Project Evolution

How this project has evolved over time

At the initial stages of consideration, designers drafted a project outline that would maximise the wind energy potential of the site. Staying in line with the guidelines, the following initial assumptions were made: The initial distance to houses was taken at 500m (subsequently increased), restricting the turbine height to 169m. Shadow flicker curtailment was taken at the maximum allowable levels.

Placing local appropriateness as a fundamental consideration, further optimisation of this design was carried out based on commonly received feedback relating to the distance to houses, number of turbines, shadow flicker and noise levels. It was found that it was possible to increase the distances to houses, reduce turbine numbers further and improve general performance levels of the proposed wind farm by increasing the tip height by 11m.
