[UK-CONTEST] Wind Farms and VHF

[MM0BQI]

Does anyone have any experience of operating within a mile of a large wind farm?  Our VHF NFD site has suddenly grown 30 150 foot high wind turbines and they are directly due south of the proposed operating site.  Will they have any adverse effect on 2m signals or generate QRM?
Previous location had them to the north which caused no problem but beaming directly at them for most of the contest could be a different story!
Thanks
Jim,  MM0BQI
