Typical capacity factors of current wind farms are between 25% and 45%. Nuance is expected curtailment [1], if there are batteries at commissioning or potentially in the future for firming and curtailment reduction [2], how this compliments solar and other generation types in the US West at delivery points, etc.

Offshore being about 10% higher than on land.

Of note is that it is in unconstrained conditions, defined by the weather; when it is needed or when a flexible production can reduce its output, or when flexible consumption can absorb it. As renewables' share increase, this is becoming a problem in some parts of the world: electricity prices can even go negative at times.
