For 4 hours now South Australian electricity prices have been zero or negative. How do we expect to run a grid reliably when such a lunatic concept is promulgated by AEMO In addition, U.S. troops and their families serving around the world to Continue to site levitra sale ensure the problem of male impotence can be taken care of. For Psychogenic or Hormonal Sexual Dysfunction, medical science purchase generic viagra doesn’t have much to offer. We repudiate unwavering quality of this data and mix-ups it could contain. But through proper treatments, this sexual problem too can be cured. the grid authority.
Price is the heavy line – demand is thin pale line.

Lunatic concept indeed Warwick, although I don’t know that it’s fair to blame AEMO for it. Sure that organisation would be professionally incompetent if it didn’t fully understand that the MRET legislation is increasingly putting the security of the electricity grid at risk, not to mention its crippling impact on electricity costs (I believe AEMO is fully aware). I’m sure there are many competent young AMEO engineers (with young families and mortgages) who fully understand this too but are forced to bite their tongues while their managers adopt a sycophantic “yes sir yes sir three bags full” approach to the politicians.
But, as Sir Humphrey might say, all will be revealed in the fullness of time. I fear the recent SA fiasco is simply a prelude to what must be endured by ordinary Aussie power users before the penny finally drops for our dunderhead, mainstream political leaders.

For over 20 years I have held the hope that a catastrophe such as this would finally stir the mass of the populace to the point where practical intelligence would finally intervene.
The SA curtain-raiser in July seemed to reduce this hope significantly as there was almost no outrage. The heavy hitters such as BHP politely told Weatherill that the situation was unacceptable – which made not one whit of difference. This engendered despondency.
Now we have a full-blown catastrophe. The graphed output of power from the various SA windfarms (wattsupwiththat.com/2016/10/01/south-australias-blackout-apparently-triggered-by-the-violent-fluctuations-from-the-snowtown-wind-farms/) shows the wild fluctuations from the windmills as a result of high winds, with complete loss of Snowtown windmill output BEFORE the Heywood inerconnector tripped out. Incontrovertible, one may think …
Yet we have the MSM peddling furiously to avoid these facts becoming public. These people are truly dangerous in their Noble Cause Corruption vanity. It has become Through the Looking Glass with Alice.
Have you noticed that these AEMO tables; Average Daily Prices (thats RRP or Regional Reference Price) Current Month
Index to monthly tables showing average prices for each day.
Show that on 4th October SA had an Average Daily Price of minus $387.82 and a Peak RRP of minus $446.81, I kid you not, look for yourself.

An obvious question arises for any inquiry; why would any gas generators keep working?
I was glancing over an article about California’s grid and wondering, how such abject failure could possibly be overlooked. The state has frequently had rolling blackouts. While they tout their renewable energy, energy companies are forced to build power plants across the border in neighboring states to meet the parasitic demands of California’s delusions.
SA’s problems too are a clear warning of the insane folly of those pushing for renewable energy. The math is plain and simple…renewables earn almost nothing while producing but require fossil fuel plants remain functioning to shadow the load. They earn less than nothing while not producing while causing energy prices to drastically increase. It is literally a buy high, sell low situation. And their use absolutely requires sacrifices be made…while they give no benefits, not even a meaningful carbon savings (if there can be such a thing).

The Weatherill version of events looks dented to me.
On p2 the reports says –
Immediately before the event, approximately 880 MW of SA wind generation, 330 MW of SA gas generation, and 610 MW of electricity imports via two interconnections with Victoria were collectively supplying 1,895 MW of electricity demand1 to SA’s 850,000 customer connections.here was no reduction in thermal generation. Each reduction coincided with a drop in voltage observed at the wind farms’ connection points.
My comments:
Adding up all the generation you get – 1,820MW – yet they say demand was 1,895MW. Clearly they were skating on very thin ice – at a time they had chapter & verse warnings of bad weather – should have had more gas fired booted or booting. You need some “spinning reserve” to keep a grid safe. Sloppy management – IMHO
Here are 6 points where I think the AEMO report needs improving.
Points where the AEMO report is misleading or could be improved.
[1] Many placenames on the map of SA grid are illegible – sloppy work for a big well paid organization – map is on pdf page 31/31.
On page 5/31 EXECUTIVE SUMMARY – In Pre-Event – they say –
[Immediately before the event, approximately 880 MW of SA wind generation, 330 MW of SA gas generation, and 610 MW of electricity imports via two interconnections with Victoria were collectively supplying 1,895 MW of electricity demand..]
[2] Adding up all the generation you get – 1,820MW – yet they say demand was 1,895MW. So by their own numbers clearly they were skating on thin ice – at a time they had warnings of bad weather – should have had more gas fired booted or booting. You need some “spinning reserve” to keep a grid safe – they had none.
Same page pdf 5/31 under Event.
[The weather resulted in multiple transmission system faults. In the short time between 16:16 and 16:18, system faults included the loss of three major 275 kV transmission lines north of Adelaide.]
[3] “north of Adelaide” is a vague and unsatisfactory term in a technical report. It could mean Edinburgh or Port Augusta – not good enough AEMO. The term is used more than once.
[4] You have to read down to pdf page 16/31 to find out in the last 2 lines in
3.2 Network damage resulting from the storm
[Data currently available to AEMO indicates that the damage to the Davenport – Brinkworth 275 kV ……. occurred following the SA Black System.]
So the majority of downed towers were damaged AFTER the SA Black System.
And if I read things right all downed towers were in the far north near Melrose – Port Augusta.
[5] Locations of the downed towers should have been explicitly marked on a clear map.
[6] This all means that the core region of the SA grid – Murraylink, Heywood Interconnector and the grid south of Clare through Adelaide to the South East – south of most wind farms – suffered no downed towers – and should not have gone black if sufficient gas fired generation had been available.
I see the South Australian Price and Demand charts no longer show here:
www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data-dashboard#price-demand
showing charts with hours & hours of negative prices is too paranormal maybe? Even for SA.

The map is a PDF format, which is supposedly vector-scalable, ie. detail is not lost on zoom. So the detail we need in a map is simply not there at any reasonable resolution to begin with. This isn’t “sloppy” work, it is DELIBERATE, so that we out here in Mug Q Publicland cannot decipher facts sufficiently well to ken when we are being lied to.
And the irresolution of AEMO about WHY the windmill farms suddenly “disconnected” (such delicate bureaucratic language) is also a two-boot shuffle to the left. This is to avoid accurate, if early, assessment of potential criminal liability, as evidenced by AGL’s dissembling comment to the effect that maybe the windmills’ safety systems were set too protectively – no more detail than that silly armwave.
It is really hard not to despise some Australian authorities. Their abuse of power is overwhelming.
