Bit of a wind drought drives AEMO RRP into the stratosphere in SA – the interconnectors must be humming. Check button for SA and you can toggle between 30min and 5min data graphic.
At $14,000 per MWh generator bikes would be viable earners.
NemWatch shows SA wind at 4MW. Wind across SA, Vic, NSW, WA(200MW) only 332MW.

For my updated chart of daily AEMO RRP across four states.
Updating my chart of daily AEMO RRP prices across SA, NSW, Qld, Vic – we see the great South Australian price explosion of June which affected all states. Then by mid July prices in NSW, Qld, Vic were crashed back to pre-June levels – SA prices took a week or two longer to fall. Looking at the 30 day smoothed trend. For large chart.
Queensland prices have risen post July and rival levels in South Australia – why would this be?
New South Wales prices have risen post July but recent softness leaves the 30 day average just above $50.
Victorian prices have fallen post July and now look similar to April 2015.
South Australian prices slumped into September but since October continue their starring role.
It is interesting that the lunacy of negative daily prices is appearing in NSW. Periods of low prices tend to be when winds are strong – check chart to MW. NemWatch gives a realtime picture of generation.
AEMO is fine tuning their story with another edition out.
– at least this edition has a better map. Any idea of the blackout being caused by wind blowing over transmission towers seems to be vanishing. Now the blackout seems due to wind generators cutting out after being subjected to a specified number of faults. Alan Moran says – South Australian blackout: it was, in fact, caused by the windfarms – he also raises issue that consumers who have suffered losses could claim compo.
Followup stories on the ABC –
SA Treasurer vainly beating his drum that wind power is never to blame.
Chris Uhlmann reviews the AEMO update
We now have 5min data which shows that wind on the 28th was lower than the peak on the 26th despite wind being stronger on 28th.
Here is a table over 3 hours – When you compare demand against – import + gas + wind it looks as though they lacked reserve. But there is also rooftop solar to factor in.
Just major voting groups percentages – data mostly from ACTEC and the ABC. The hordes of various “independents” in early ACT elections seems remarkable. Greens must be annoyed their big totals in 2008 have melted – the ACT should be GreenLeftie heaven. One seat in doubt as Labor maintains grip – Interesting that the ACT Libs did not offer a policy difference with the ACT Govt renewables energy target of sourcing 100% renewable energy by 2020.
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 the grid authority.
Price is the heavy line – demand is thin pale line.
Here is the SA page at the Grid Public Knowledge wwwsite by Peter Bobroff.

Government’s energy policy worsened South Australian state-wide blackout
Are scales falling from State Govt eyes too?
Rely on wind power – decommission your reliable coal fired generators – who could be surprised at a blackout. Nemwatch. As I write the AEMO Electricity Price and Demand www site shows none of their usual charts & data.
The weekend has seen a welter of speculation about the closure of Hazelwood neatly timed with a report by the Grattan Institute titled – Keeping the lights on. Victoria has the following coal fired generators – Hazelwood 1600MW –
Loy Yang A 2180MW – Loy Yang B 1000MW – Yallourn W 1450MW
Total 6230MW = possible max 149,520MWhrs per day
If Hazelwood shuts the total coal fired generating capacity reduces to 4630MW making for a possible max 111,120MWhrs per day if all units operated 24/7.
This chart of Vic daily generation by source (omits solar) shows the current dominance of coal – for large chart. I have marked with the pink X where a horizontal line would be drawn at 111,530MWhrs per day. So just below that would mark 111,120MWhrs per day. Without some way of replacing the reliable 1600MW capacity of Hazelwood – it seems amazing that the media run with this fairy-story.
Electricity prices at AEMO have spiked to over $250 per MWhr across Australia in the morning rush – Nemwatch shows wind through the “National Grid” (excl WA) is under 250MW. The Wind Energy site shows how this wind drought is now in its third day. None of this is news in the GreenLeft main-stream-meedja. Imagine the headlines if coal or gas fired generators were to fail like this? Write your MP’s and Senators – call for a moratorium on wind power – say you will vote to curtail the excesses of the MRET scheme and for sensible electricity prices.
