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.
