Markie Mills, it unfortunately for those poor South Australians is great news for AGL. AGL may now concern itself with security of supply and may get better margins out of this. BHP's Olympic Dam is out, Arrium funded by the Federal Government is out with molten steel cooling. Companies such as AGL, ORG, APA and STO will make an absolute motza out of this as the blackout looks likely to have been easily avoided had a disaster recovery plan or backup plan been in place which did not RELY on renewables filling the void.

If Port Augusta was still on line, if there was a better energy mix not reliant on the Victorian interconnector and renewables to fill any void like what happened this week, would the blackout have still happened?

Ideologues may deny the problems with energy security created by renewables when the evidence so far points not yet completely conclusively in the opposite direction.

It will matter zip. The Federal Government will ensure the States make energy security the top priority. AGL will reap the rewards of that IMHO.
