To what extent is Wind reducing spot prices in South Australia?
Some starting thoughts, about the extent to which increased wind farm output has been responsible in the drop in spot prices in South Australia from the high levels seen in 2008.

Prices see-saw across the (mainland) NEM today
An interesting day in the NEM today, with prices gyrating across a wide spectrum, and across all four mainland regions – on the back of higher demand in Victoria and South Australia due to temperatures there, and supported by transmission issues and other factors.
Prices soar as the south-east sizzles – with summer arriving early
Some quick observations about the price spikes observed yesterday on the back of high temperature-driven demand in Victoria.
A very volatile day in VIC and SA (not particularly due to the Carbon Tax)
Some quick notes today, on day #2 of the Carbon Tax, prompted by some prices that jumped all around the place (not so much due to carbon, though).
A hot Saturday could have driven demand higher – but how much?
A quick look at the demand levels on Saturday 25th driven by hot weather in VIC and SA. What would have happened had this been on a weekday?
Hot in VIC and SA – but demand not climbing past the green zone
High temperatures in Victoria and South Australia – but demand is still well down on the all-time records for those regions.
Price spikes in SA and VIC on 21st April
Just after midday today (Wednesday 21st April) South Australia and Victoria experienced some high spot prices. Here’s a quick post to highlight what happened.
Playback of high prices in SA and VIC
Prices in South Australia and Victoria have been high this afternoon, jumping up over $2000 in both states at 3pm NEM-time today.
Ouch – VOLL in SA, close to midnight!

How helpful was NEMMCOs PASA process in predicting the demand spike on 29 January 2009 (part2)
Some further analysis of the MT PASA and ST PASA forecasts for other regions of the NEM (SA, TAS, NSW and QLD) for the day of 29th January 2009 – when a new record NEM-wide demand was established.
High temperatures force demand high, NEM-Wide (and prices follow)
A few brief notes about a hot day across the mainland, with demand levels high in each of the 4 mainland regions
South Australia hits the Cumulative Price Threshold
For only the 5th time in 11 years of NEM history (and the 3rd time for South Australia) four consecutive days of price spikes have forced the Cumulative Price to the Threshold, and AEMO has imposed price caps to prevent retailers from going bust.
Tight supply-demand balance in SA today!

Massive Demand, Huge Prices, Load Shedding and the Cumulative Price Threshold (and lessons learnt?)
Wednesday 28th January saw demand across the NEM jump to unprecedented levels, setting a new record of 34,843MW at 16:00 NEM time. On Thursday 29th January, we saw the demand increase still further, leading to prices that stayed high for much of the day (to the point where the Cumulative Price Threshold was reached in VIC and SA and price caps were imposed), and a relatively small amount of involuntary load shedding occurring in VIC and SA.
New record all-time NEM-wide demand (and for VIC and SA) today!
The day is not over yet, but we thought you would be interested in the attached snapshot highlighting the first of the occasions on the day when prices jumped to VOLL in SA and VIC as a result of searing temperatures stopping the tennis, and melting VIC and SA into new demand records for each region.
SA nears the Cumulative Price Threshold
On 19th January, high prices were sustained in SA for several hours, bringing the Cumulative Price within a whisker of the $150,000 threshold, at which prices would be capped.
Our review of the heat wave in South Australia
With demand soaring, and interconnectors constrained, generators in South Australia and Victoria took what opportunity they had to force the price high. So successful were the South Australian generators that the Cumulative Price Threshold was reached in South Australia and, under NEM Rules, an Administered Price Cap was applied for a period of time.
