The production from the wind turbines depends upon the actual wind speed. As wind speed increases the turbines' output will increase accordingly. The increase can be seen on the power curve for the WTG.

The wind turbines start to generate power at a wind speed of only 4m/s, and level out at 3,6MW at a wind speed of 12-14m/s. When the wind speed exceeds 12-14m/s, the turbine will automatically and gradually pitch the blades out of the wind so as to prevent overload. If the wind velocity exceeds 25m/s, the turbines will disengage for safety reasons.

At a wind speed of 9 m/s, which is the expected average wind speed on the site, a total volume of 80,928 m3 of air is passing through the rotor every second. This equates to almost 100 tonnes of air per second!
