Yesterday we saw relatively high winter evening peak in demand, coincident with low Instantaneous Reserve Plant Margin right across the NEM – but relatively subdued prices.
Not so much this evening (Tue 6th July 2021) ….
Here’s a snapshot from NEMwatch v10.2 (the version being developed for Five Minute Settlement) at the 17:30 highlighting several things:
I’ve annotated how:
1) ‘Scheduled Demand’ has climbed out of the ‘green zone’ in NSW and we can see it is climbing further at this time. So with it NEM-wide demand as well.
2) The IRPM right across the NEM has dropped under 12% … hence the red alert colour in NEMwatch above.
3) Price have obviously spiked in all 4 x Mainland regions (this was the first of a number); and
4) Supply from Wind (and, of course, Solar PV) has declined this evening, with it looking like it will continue to trop further for a while.
… and there are other observations that can be made.
With gas prices elevated currently, this will make for ‘interesting’ viewing this evening…
