A very quick post prompted by the predispatch outlook for the rest of today and tomorrow:
With Adelaide at 42 degrees and Melbourne over 35 today, and similar-to-hotter forecasts for tomorrow, Thursday could be an interesting day in the southern NEM regions.
At the time of writing we’ve seen one 5 minute spike to just under the $14,000/MWh Market Price Cap in South Australia (driven by a short reduction in the Vic to SA export limit on the Murraylink DC interconnector), with more shown in predispatch, although that’s been changing considerably through the afternoon.
AEMO is forecasting combined SA + Vic demands peaking at over 11,700 MW tomorrow afternoon, nearly 1,200 MW higher than seen so far this summer, and the highest for three years. That is a key driver for the extended price spike shown on the predispatch forecasts for Thursday – although there is plenty of time for demands, generator bids, and other things to change between now and then.
