Exactly why I say people touting it as if its some magical meaning.
'The
availability factor of a
power plant is the amount of time that it is able to produce
electricity over a certain period, divided by the amount of the time in the period. Occasions where only partial capacity is available may or may not be deducted. Where they are deducted, the metric is titled
equivalent availability factor (EAF). The availability factor should not be confused with the
capacity factor. The capacity factor for a given period can never exceed the availability factor for the same period. The difference arises when the plant is run at less than full capacity, in which case the capacity factor is less than the availability factor.'

So it looks like they might be deducting it
