Capacity Factor

The capacity factor of a wind turbine is equal to its mean power output divided by its rated power. The mean power output is often calculated over one year or one month, but it could be calculated over any period.

The term gross capacity factor refers to the gross mean power output (before accounting for losses) divided by the rated power. The term net capacity factor refers to the net mean power output (after accounting for losses) divided by the rated power. Windographer reports net capacity factors on the Wind Turbine Output window.
