There’s been a solid block of windy weather triggering weather warnings in recent days and, more specific to the NEM, meaning another increase to the ‘all time maximum instantaneous NEM-wide’ record set only a couple weeks ago.
Here’s a snapshot captured this morning looking back a-day-and-a-bit to highlight the new peak at 7,305MW set as InitialMW for the 20:50 dispatch interval Thursday evening 4th August … so metered at 20:45:
This new ‘highest ever’ point was almost 200MW higher than the level of 7,111MW set for the 21:50 dispatch interval on Saturday 16th July 2022.
There was also an interim bump to 7,253MW on 3rd August that I did not write about as well.
Bit of a coincidence that the new record level was set at the same time as the Albanese Government’s new climate legislation passed in the lower house … but also food for thought as well.
As I have noted before, the NEM is fast becoming a market (and a machine) that both extremes are going to matter increasingly :
1) so whilst we should celebrate these highest points,
2) we should still remember (as illustrated here and in other articles) that the minimum points each month are still stubbornly low and (as we showed in Appendix 27 within GenInsights21 should always be expected to be that way, no matter how much wind capacity we build and how widely it is spread).
The design of the NEM 2.0 we arrive at through the current process on the Capacity Market and through other initiatives needs to ensure there’s always enough dispatchable capacity to cater for these lulls, whether short term or rarer longer-term ‘wind droughts’.
