Definitions of Availability Terms for the Wind Industry

The term "availability," as used in the wind industry, is a measure of the potential for a wind turbine or wind farm to generate electrical power. If the turbine is "available" and grid-connected, and the wind and other conditions are within the turbine specification, then power will be generated. The availability figure is used
