Wind Energy Capacity Factor Calculator

Estimates a wind turbine's capacity factor — the ratio of actual output to maximum possible output — and annual energy yield. Use it when evaluating a site's wind resource or comparing turbine performance specifications.

Wind Farm Capacity Factor Calculator

Calculate the capacity factor of a wind turbine or wind farm, the fraction of its theoretical maximum output that was actually delivered over a period. It is the single most important metric for comparing real-world wind project performance.
