Brief Case Study of Sunday 4th February 2024, with low IRPM following high Market Demand

Posted by Paul McArdle Saturday, April 27 2024 Topic: 2024-02-04 Sunday (High demand, low IRPM, etc), Summer 2023-24 in the NEM

As it happened we had noted ‘NEM-wide ‘Market Demand’ reached 32,938MW on Sunday 4th Feb 2024 (updated)’.

 

Now that we’re reviewing 2024 Q1 more systematically, we’re starting to see other things as well – which are being explored and explained in the GenInsights Quarterly Updates for 2024 Q1 report.  To assist in that process, we’ve posted here this 3-day trend covering Saturday 3rd February, Sunday 4th February and Monday 5th February 2024 (produced with NEMreview v7):

In the 18:40 and 18:45 dispatch intervals the Instantaneous Reserve Plant Margin (i.e. IRPM) dropped to a low point of 17.7%:

1)  Note that this was 25-30 minutes after the daily peak in Market Demand, as noted in the earlier article

2)  We can see in the chart above that supply from Large-Scale VRE continued to drop more quickly than the Market Demand.
