Remember a Wind turbine is rated at its absolute continuous Max Output. Power output goes up by WS³ so it does not need to be much below optimum to lower the output by 75%. If wind goes over by 10 to 20 % You get full power but no more. It varies by design but usually at 20% to 50 % of optimum wind speed they have to lower output to prevent damage Eventually feathering blades for full shut down in high winds.

So on a yearly KWH output basis on this many generators figure total output is probably25% to 50% of max output x time.

Every Gen manufacture offers different blades for different wind profiles. Usually 2 to 4 different ones. For low wind speed blades are wider and have a shallow attack angle, high speed are narrow with a high attack angle. Once you pick one you have to live with it. Global Warming is giving us much larger swings in weather and this is not good for wind, solar, or Hydro. We Need to do all 3 but also need to understand limits and what you really get.

WS³ is Based on a fix blade with no pitch adjustment. Pitch adjustment helps at low speed and high speed. But ultimately it comes back to the basic physics. Same is true of a sail boat. The power is constant but you can adjust sails to change efficiency. Air drag of a car also goes up by WS³.
