Wind Turbines and GPDO - Public forum - Planning Advisory Service (PAS)

I wonder if you may, be able to help me. I am looking for what I suspect is a rare beast, which is specific examples of Wind Turbine installations permitted by the GPDO? Be they roof mounted or freestanding.

I am completing a dissertation for a planning MSc and any examples you may have come across would be very gratefully received.

Thanks

Stuart
