1) Green Disaster: South Australian Blackout Due To Loss Of Wind Power
The Australian, 5 October 2016
Graham Lloyd
A dramatic, sudden loss of wind power generation was the root cause of South Australia’s state wide blackout last week.
Preliminary Report – Black System Event In South Australia On 28 September 2016 — Australian Energy Market Operator
And the bulk of damage to high voltage transmission lines that was caused by high winds and paraded as evidence to defend renewables most likely took place after the power had been lost.
These are the major facts contained in the Australian Energy Market Operator’s (AEMO) preliminary report.
More work is needed to flesh out the forensic, time sequenced analysis that has already been conducted.
But there is enough in the interim report to make the rush to defence of renewables mounted by special interest groups and conflicted state governments since the lights went look foolish.
Certainly, the power would not have been lost were it not for the big storm.
And seven big towers were damaged in the lead up to the blackout.
But AEMO said data currently available indicates that the damage to the Davenport to Brinkworth 275 kV line on which 14 towers were damaged “occurred following the SA Black System”.
The big event was a 123 MW reduction in output from North Brown Hill Wind Farm, Bluff Wind Farm, Hallett Wind Farm and Hallett Hill Wind Farm at 16.18.09.
Seconds later there was an 86 MW reduction in output from Hornsdale wind farm and a 106 MW reduction in output from Snowtown Two wind farm.
No explanation was given for the reduction in wind farm output.
But the loss of wind farm production put too much pressure on the electricity interconnector with Victoria which cut off supply.
This in turn led to a shut down at the Torrens Island power station, Ladbroke Grove power station, all remaining wind farms and the Murraylink interconnector.
AEMO says a lot of work is needed to fully explore what happened.

2) Australian Energy Market Operator Orders 10 SA Wind Farms To Limit Generation After Statewide Electricity Blackout

TEN South Australian wind farms have been ordered to limit generation in the wake of the disastrous statewide power blackout because the national electricity market operator has declared they have not performed properly.
The state’s biggest wind farm, at Snowtown, is among those which the Australian Energy Market Operator has targeted in its “management and analysis” of last Wednesday’s unprecedented power outage as it gradually restores the power network.
The move will prompt further questions over whether renewable energy jeopardised electricity grid stability and triggered the cascading blackout, which started when fierce winds damaged 23 Mid North transmission towers and severed three high-voltage lines.
Premier Jay Weatherill, who on Tuesday revealed former police commissioner Gary Burns would lead an independent review into the catastrophic storms and power outage, said he expects a preliminary report from the national electricity market operator by late on Wednesday.
The 10 wind farms, all but one in the Mid North, were the subject of a national electricity market notice issued late on Monday night, in which AEMO says it is not satisfied that a failure, or trip, of multiple generators, following another disruption to the grid is “unlikely to re-occur”.
Asked to explain, an AEMO spokesman said it had been established that some South Australian generators “had not performed as AEMO would have expected” but did not say whether this was before or after the statewide blackout.
“While further analysis needs to be undertaken to identify the cause (of the statewide blackout) and any remedial steps, AEMO must continue to manage the power system to avoid any further risk,” the spokesman said, in a statement to The Advertiser.
He said the power grid’s security could be maintained, in the face of a credible perceived threat, by limiting generators’ output or the flow on transmission lines to “minimise the risk of a significant supply/demand imbalance”.
AEMO did not respond to The Advertiser’s questions about whether the wind farms in some way contributed to a cascading power grid shutdown, once the high-voltage pylons were toppled.
Announcing Mr Burns’ appointment, Mr Weatherill said he would examine the circumstances surrounding the storm and consider the state’s plans for prevention, preparedness, response and recovery.

Why wind power. The middle of Australia is a barren desert where the sun shines every day. Can anyone see the obvious here?
