Wind plant performance—how much electricity a wind plant generates compared with its maximum possible generation—depends almost entirely on the availability of wind resources, which vary depending on both the time of year and the geographic region.
The performance of a power plant is often characterized as a percentage of the maximum possible generation in a given time period, a metric known as capacity factor. Nationally, between January 2016 and August 2022, wind plant capacity factors peaked in March and April and were at their lowest in July and August.
