How wind speed affects turbine power production

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 where a turbine will be stopped due to the high wind speed, in order to prevent possible damage. Now you know the three types of wind speeds that impact wind turbine operations and power production!
