So, a once in a 50 year storm smashes Adelaide and the ports, and knocks down about 22 high voltage transmission lines. This causes the grid to go open circuit in several places as a safety feature, meaning almost the entire state is without power.

Amazingly, less than 24 hours later, 90 percent of the state has its power back on, but several places will be without power for days as the lines are restored.

Now, if you were a fossil-fuel zealot who has a set against renewable energy, it would be pretty darn hard to resist the temptation to turn this into an issue for your own gains...

Surely a decentralised generator network (including wind, solar, gas and others) would have prevented this event from getting out of hand? Or at least an improved set of over-current and frequency safeguards?

Perhaps the battery revolution just got it's big opportunity?

Yes, it's sad to see some politicians using this to push their own anti-renewable agendas when it's pretty clear that the energy source is irrelevant to the issue.

The generator network is scattered all over the state including two separate interconnectors to Victoria, so while I wouldn't call the network centralised per se, I would be asking questions about the transmission infrastructure particularly around redundancy and isolation abilities.

no power? well you carnt pump the gas then :-)

how ever the EVers can just top up from there solar panels and keep driving

There a pro's and cons for both.
Scattered wind turbines in a once in 50 year storm wouldn't fair much better.
There isn't enough batteries in Australia to buffer all of SA.
Guess they could wait 2-3 months without power for the upgrade.

I'd say it's just better to fix what they have and think of it as a wake up call and start planning before the next 50 year event.

Everyday I get updates on people/companies jumping on the microgrid bandwagon.
Every suburb has a school, shop, park and microgrid solar/battery power station...
It'd be like the internet, one hub goes out 4 others back it up.

Wind generation was around 1MW prior to the disconnect.

In any rate losing 20 add transmission towers will affect supply in a big way.

SA isn't a big state.
