(Afternoon and) Evening volatility in NSW and QLD on Monday 2th December 2024

I’m back in the saddle today after taking a break and landed interstate to a barrage of queued up text messages notifying me of high prices in NSW and QLD from 17:35 (NEM time) on Monday 2nd December 2024:

Note the 4 dispatch intervals above $1,000/MWh early this afternoon in NSW … but let’s use Time-Travel in ez2view to take a look at the 17:50 dispatch interval, which was the first dispatch interval where the price in NSW and QLD was up near the Market Price Cap:

In this case see see that:

1)  VIC1-NSW1 is constrained at the maximum export capability (i.e. flowing VIC into NSW, which is what you’d expect, but which we’ve seen before does not always happen)

2)  Various DUIDs in south and western NSW are subject to bound constraint(s), but the effect this time is ‘only’ shifting their CPD Price(s) down to levels of $1,000/MWh (i.e. down from bright red to pink)  … so presumably not many actually being constrained off.

3)  So may have been more just a case of stretched supplies.

Nothing further at this point.
