NSW ‘Market Demand’ peaks at 13764MW

Whilst I was looking back at the first spike (at 15:10), Dan Lee noted that spikes resumed  at 16:25 (with the 14 dispatch intervals in between all still elevated).

Another 13 dispatch intervals later (at the 17:35 dispatch interval NEM time) here’s another snapshot from NEMwatch to illustrate that the spikes continued from 16:25 onwards more solidly:


We also see a few other things, including that:

1)  NSW ‘Market Demandpeaked at 13,764MW (in the 16:35 dispatch interval)

(a)  … so clearly the highest for summer 2023-24.

(b)  and also ‘only’ 885MW below the all-time record (of 14,649MW – which occurred on 1st February 2011).

2)  We see the IRPM for both ‘Economic Islands’ formed by constraint operation (i.e. for QLD only and for NSW only) down in the ‘red zone’ indicating the tight supply-demand balance in both locations.

3)  There’s lightning in northern NSW so AEMO has noted ‘Reclassification of a Non-Credible Contingency Event: Armidale – Dumaresq 8C 330kV line and Armidale – Sapphire WF 8E 330kV line in NSW1 due to Lightning.’

4)  Not shown here, but the AEMO also re-activating the ‘Actual LOR1’ alert level for NSW at 16:00.


Another interesting/challenging summers day … (the last one of summer, officially!)
