This is the Repower MM92, rated power: 2000kW, rotor diameter: 92.5m, hub height: 100m. These turbines usually shut down at about 25 m/s or 55 mph, this is the maximum operational limit The time span in the video is about 2 hours while the wind speed went up from about 18 m/s to 30 m/s. When the wind was gusting up to 30 m/s the rotor blades were pitched out of the wind.

This is the Enercon E-126, the first wind turbine with 6 MW rated power, rotor diameter: 126m (413ft), hub height: 135m(450ft). Two of these giant wind power units have been built for testing at an onshore location, Rysumer Nacken, near Emden, in the northwest of Germany.
Here each WPU is expected to produce about 18 Mio kWh per year, enough for more than 4,500 homes.
