We got many big windfarms here in Denmark.
But they are all located far out from the coast, where noone gets influenced by these
Smaller "farms" if one can say that, say 5 to 10 turbines on a harbour, and some places only 3 maybe, are common though, and we have ridden behind these for many years, so my experiences:
You CAN actually ride just behind a line of wind turbines, say only 10 meters away straight along a pier, so kite maybe up only 20-25 meters away, up in the turbulence from the wings.
We do that at wavespots, where the waves are best at this precise location.
BUT, the wind is horrible, kite can suddenly turn "around" and drop, or you get a huge powerspike - really scary the first time you encounter this.
One can learn to handle it though, fly the kite low and fast, then you can cope with these conditions quite well, and enjoy the waves.
Not a chance, forget it...
When you come 500 meters away, the wind is still really shitty, but quite easy to ride.
1 km away, it is sometimes gusty, but okay managable to ride, or jump, very few "dump holes" (wind suddenly drop you) in the air now, but some.
2 km away, you hardly feel anything but "less smooth" wind, not even in 30 knots of wind.
3 km away, free of all (felt) wake turbulence.
When you go past to the outside, the turbulence is, like shown in the photo above, a bit V shaped so ranges wider than the turbines, but wind is very smooth very fast so in free wind
Above is when we talk about 3 to 10 turbines exactly upwind of you.
Of course with a little variation depending on wing size and type.
Have no idea about how a 59 turbine wind farm will destroy, assume it will be a lot worse and last further downwind, but now you know what you minimum can expect
