Derating - Wikipedia

This article is about electronics. For the adjustment of engines for longer engine life see engine tuning.. In electronics, derating (or de-rating) is the operation of a device at less than its rated maximum capability in order to prolong its life. Typical examples include operation below the maximum power rating, current rating, or voltage rating.

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.
