I interpret this to mean that if you have 1000MW of load to meet, you would have to have ~3x the output active (3000 MW). And based on wind industries own reliability numbers, you need 3x that for 24x7 operations because of forced outages and maintenance, or 9000MW Because of this, most jurisdictions are setting up wind farm contracts as "generate all you can, whenever you can, unless we dispatch you off".
