A very short article this evening with a single snapshot from NEMwatch v10.2 taken at 19:00, but with the 18:00 dispatch interval the point of interest:
The dispatch price spiked above $14,000/MWh in both QLD and NSW for the 18:00 dispatch interval (i.e. the last dispatch interval in the 18:00 thirty minute trading period). I’m inferring that the subsequent 300MW drop in dispatch target for Scheduled Demand in the QLD region was the result of ~300MW of (spot-exposed) Demand Response in the QLD region … the type which we’ve been serving for what’s approaching 20 years.

A Market Event Report has been published on the NEMMCO website discussing the market outcomes of the high energy prices in the New South Wales and Queensland regions on Friday, 31 October 2008.
The multi-region islanding event on Saturday 25th August was a very rare event – perhaps the only one’s that occurred in the history of the NEM. It has generated plenty of questions – and driven our analysis further. We share some more observations here, and keenly await the draft AEMO report.
