Yeah, the national market probably needs a review.
Anyway the power is being restored.
What's needed is another interconnector between SA and NSW.
They just have to decide who will pay for it and the method of payment.
There is abundant generation capacity on the East coast.
One problem SA has is that the gas fired station operators, no longer being State owned, can make more money selling their contracted gas supplies on the open market rather than producing electricity.
What happened today is that such a large amount of capacity, relative to the grid size was removed without warning.
The Victorian interconnector couldn't supply the demand so was shut down.
After a voltage collapse the system is slowly brought back up, matching supply with demand.
Similar has happened in the past even when SA was an electricity island, State owned, with many more staff.
Unlike some other States with bigger grids, a major outage in SA probably has more chance of causing a Voltage collapse.
To do the same in a state the size of NSW would require a much bigger catastrophe.
