Thank you all for the comments. I'll try to answer as many questions as I can.
This particular turbine is a 1.5 mW unit installed in Texas. I took the pic's just today. We are preparring to replace a blade. Lightning can be a bitch. This is one of our shorter ones with a hub height of 65 meters. Using the platorm for some stuff I can't really discuss. You know how it goes. Wind was at a steady 8 m/s but we saw some gusts up to 10.
Plenty of maintenence to perform on these things. Not so much for certifications but to keep them running. Our key metric is availability. Keep em running to make the money. The crews at the farm do all that. I just visit the sites when we need to prototype something new.
Wind farms in the US are among the best in the world. Usually at least 100 turbines and as many as 250.
Here's a few more pic's from the platform.
