What does the capacity factor of wind mean? - Energy Numbers

The capacity factor is the average power generated, divided by the rated peak power. Let's take a five-megawatt wind turbine. If it produces power at an average of two megawatts, then its capacity factor is 40% (2÷5 = 0.40, i.e. 40%). To calculate the average power generated, just divide the total electricity generated, by the number of hours.
