i think there lies the problem.
we've heard from the sale people, we're heard from the pollies, we've heard from the end users
but we've not heard from any engineers.

Musk is not alone in the battery field, but he's pretty good at self promotion.

That's one facility in SA...
How long is that little battery farm going to last

The last load shedding event in SA needed 100MW load reduction for around an hour. You don't need batteries to run the whole state until a few more gas plants fail to proceed. One step at a time.Problem: 12141666 MWh

Yes, that's the thing, engineers are used to working quietly and without fanfare. However Musk is good at throwing bangers under people's bums and is known to get things done, if not always as fast as he says he will. Interesting times, indeed.

Today they seem to be able to educate them AND retain a personality
I see they're also looking at pumped hydro.
SA power: State Government to unveil electricity market intervention plan - ABC News (Australian Broadcasting Corporation)
The SA Government seems to have decided it has to go it alone and make the state energy self-sufficient, so it doesn't need to rely on anyone else and to prevent a repeat of the market failure, since there is no effective national energy policy from Canberra to guarantee the supply to the public.

Subscriberits been reported in the news:
BUILDING a State Government-owned, fast start gas-fired power station that can come on when the market does not provide enough energy to keep the lights on. It is expected to cost about $360 million. No site has yet been selected. It would be 250MW, enough to deliver close to 10 percent of SA’S peak demand.
SUPPORTING construction of Australia’s biggest battery as part of a $150 million spend on a new renewable technology fund.
ENCOURAGE the construction of a new privately-owned power station using a Government bulk buy power contract.
INCENTIVISE the extraction of more gas for use in SA power stations, through a taxpayer-backed exploration fund.
GIVING the SA energy minister powers to over-ride other regulators and force power stations to fire up in times of need.
CREATING an “energy security target”, which requires retailers to buy 36 percent of their power from baseload sources in SA.

Subscribernew report out.

we came so close to a complete blackoutAt 1503 hrs (AEST) on 3 March 2017, a series of faults at ElectraNet’s Torrens Island 275 kilovolt (kV)switchyard resulted in the loss of approximately 610 megawatts (MW) of generation in South Australia (SA)across five generating units.
Although AEMO did not instruct load shedding, and there was no operation of the under frequency loadshedding (UFLS) scheme in SA, there was a 400 MW drop in demand in SA as a result of this incident.
AEMO’s conclusions related to the incident are: This non-credible contingency was initiated by the explosive failure of a capacitor voltage transformer inthe Torrens Island 275 kV switchyard. The loss of generation at Pelican Point Power Station was unexpected, and was caused by anunexplained protection operation within ElectraNet’s switchyard at Pelican Point. This protection hasbeen removed from service, pending further investigation. The loss of the TIPS B2 generating unit was unexpected, and was caused by the failure of the boiler airheater drive. The cause of this failure is still under investigation by AGL.
There are close similarities between this event and the SA black system event on 28 September 2016 in that there was a large sudden reduction of generation in SA that resulted in the power flow across the Heywood Interconnector exceeding normal operating limits. Voltage levels at South East substation (SESS) were not as low as on 28 September 2016 – if they had been lower, the Loss of Synchronism (LoS) protection that disconnected the Heywood Interconnector in that event would have operated again, resulting in another black system event.All wind farms in SA successfully rode through a series of three transmission faults in short succession
on 3 March, indicating the changes made to their protection system since 28 September 2016 have
been successful. AEMO has not identified any sustained reduction in output from the wind farms as a
consequence of the faults on the transmission system.
