Given the “choke” problem no amount of good days save the grid from dying on a bad day. No feasible storage is in sight to get over the troughs between the peaks of wind and sun.
Much talk of our great resources of wind and sun. Great land resources as well, but how much is arable? The BOM records probably indicate limits to farming, were they consulted to check the continuity of wind and solar supply?

AEMO data demonstrate that wind and solar cannot work without storage and should never have been subsidised to increase the cost of power and destabilize the grid.
