They can theoretically produce 188MW of power, they don't even get close to that. Not only that, most of the time electricity is required, they are calm and or the graph goes up and down like a yo yo which doesn't help anyone.
That is the elephant in the room of wind power. You have to have base load power generators - coal, gas, geothermal, hydroelectric or our good friend newcular.
NZ actually do wind power fairly well, as a couple of major cities are adjacent to some very windy areas of low population density. I understand Denmark is in a similar position. NZ also do geothermal and hydroelectric base load production in a fairly big way.
But even in those two places, wind power requires subsidies and tariffs to be competitive. I can't see Australian wind power being competitive in the foreseeable future.
