For most electricity generators, availability is the same as capacity value, i.e., the percentage of time that a plant can be reliably called on to provide power in response to demand, i.e. how much of the time it is not shut down (e.g., for maintenance or repair).
Wind turbines, on the other hand, are typically “available” over 90% of the time but have a capacity value of zero, because they are available only to the wind (should it blow), not as actually needed by customers on the grid.
