I can't even comprehend that kind of power, that's amazing and we need more of them! I use about 7.2MW a year and that's really, really low so anything MW is great.

This German company called ENERCON is making large scale commercial wind turbines in the 330 KW to 5MW range.

The reason I mention this is because they have very few moving parts and they use a "annular generator", much like our little wind turbines for home use.

They also have one hell of a grid tie inverter!

They do one thing we don't do, they pitch the blades with a CPU to control speed and optimize power output.

I see no mention of a dump load so I assume they just pitch the blades in a way that they will stop in high winds or grid outages.
