Once the rated wind speed has been reached, the turbine blades will pitch (rotate to change the angle of the blades) to continue optimal power production, while not exceeding 16 rotations per minute (RPMs). If the wind speed exceeds 22 meters per second, it will reach what is referred to as the "cut-out" wind speed. This is the threshold

Then, how much power can be captured from the wind? This question has been answered in a paper published in 1919 by a German physicist Albert Betz who proved that the maximum fraction of the upstream kinetic energy K that can be "absorbed" by an ideal "actuator" – not necessarily a turbine, but any device capable of converting wind energy to another energy form– is (
