Not much time to post anything detailed today, but thought the following two snapshots would be of interest…
See the following snapshot from NEM-Watch v8 that shows a price spike in QLD that occurred for the 15:00 and 15:05 dispatch intervals today.
The second snapshot is taken from our other market visualisation software (ez2viewAustralia, which is supplied to generators and retailers) that shows what appears to be a trip of about 900MW of generation capacity at the South-West node in Queensland at 14:53 market time today.
At the time of the suspected trip, we see imports into QLD increased, as shown in the following chart (taken from NEM-Watch). Further analysis shows that the reduction in output was also compensated by:
1) A drop in demand of about 100MW or so in QLD (presumably demand-side response); and
2) Increase in generation output at a number of the other nodes around the state.
