3rd: They look like they have the same broad, round nacelles as the German ones in the first picture.

If you only spend 20 minutes of the rest of your life on economics, go spend them here.

The background ones in the 1st & 3rd photo: two each from the same farm of 5 Enercon E-70 units. One of them (the one on right in the 3rd photo) is just beside the tracks, once we stopped right there, and it was the first time I heard turbine noise separate from wind noise (from this gearless unit, only aerodynamic noise, a swoosh like a landing airplane but much more silent).

The foreground one in the 1st and the three in the 2nd photo: I think those are REpower MM82s from a farm of 12 turbines. The logo indeed belongs to developer Wien Energie.

There were Vestas and Gamesa units in the area, too, but I couldn't catch them on zoomed-in photos.
