Last article today, I hope, on a day (Tuesday 1st February 2022) that must have meant the peak number of articles on WattClarity in a single 24 hour period!
I’ll start with this snapshot from NEMwatch in the 21:50 dispatch interval and discuss a few things…
With respect to the numbered annotations, we’ll address each in turn below:
(A) A brief recap on Tuesday 1st February 2022
Some much more detailed recaps will follow in the coming days/weeks (as time permits), but for now let’s sum up:
1) Price outcomes
The price has subsided to $109.73/MWh for the 21:50 dispatch interval – but this is after a sustained period of market volatility that had driven the time-weighted average price for the day up above $1,700/MWh.
2) Cumulative Price
As a result of the sustained price action, the Cumulative Price for the QLD region is now up at $911,437 …. which is not quite as high as I noted it could be in this article (comments which Mark Ludlow references in the AFR here), but was about double where it was this morning.
3) Demand outcomes
On a 5-minute basis, and looking at ‘Market Demand’ we see the QLD region peaked at 9,470MW in the 16:40 dispatch interval – but this evening (with temperature and humidity remaining uncomfortably high) it’s only dropped back to 8,060MW at this late point in time.
4) Reserve Margin
5) End of AEMO interventions
Refer AEMO Electricity Market Notices 94372
Activation of reserve contract(s) has ended.
The reserve contract(s) were activated from 17:00 hrs 01/02/2022 to 21:30 hrs 01/02/2022
The AEMO Intervention Event ended from 21:30 hrs 01/02/2022
The AEMO also summed up the results for the day in this tweet at 20:18:
(B) Looking ahead to Wednesday 2nd February 2022
With the charts set to 30-minute periods, they shift to incorporate the AEMO’s P30 forecasts … notwithstanding that there’s a bit of uncertainty now about what P30 predispatch actually refers to (see Tripwire #1 and Tripwire #2) under the 5MS arrangements. With the advantage of these charts, we have noted the following:
6) Demand forecast
(a) Clearly how much the ‘Market Demand’ in QLD was lower than previous forecasts … due to a number of factors we’ll discuss later in another article; but also
(b) How the current demand forecast for tomorrow is holding fairly steady … with the peak expected to be 10,041MW in the five minute period ending 17:00 (NEM time)
7) Price forecast
We did not hit the Cumulative Price Threshold today … but there’s every chance we might do so tomorrow.
8) Available Generation forecast
As was the case today, the AEMO forecast shows a decline in Available Generation capacity through the afternoon … which will be another challenge to manage.
9) AEMO negotiations
The AEMO needed to dispatch RERT today, and is actively exploring the possibility of doing the same tomorrow, as noted in the Market Notice 94411 published at 20:13:01 this evening:
