Small (NEM Mainland) frequency wobble, on Thursday afternoon 7th November 2024

Perhaps contributing to the early start to price volatility in NSW this afternoon was the wobble in system frequency shown here:

2024-11-07-at-14-35-NEM-Mainland-Frequency

 

Here’s a snapshot from the BOM cloud map with a timestamp of 13:30 (NEM time) … so that snapshot’s taken ~50 minutes prior to the NEMDE run producing the price for the 14:25 dispatch interval (NEM time).

The cloud pattern will probably have moved somewhat over that period, but seems to suggest some sort of impact of cloud on rooftop PV:

1)  Contributing to ‘Market Demand’ forecast difficulties; and

2)  Potentially then into price?

3)  And impacting on System Frequency

  1. The by-now-familiar constraints on transmission from southern NSW towards the load centres north seem to be playing their part in this volatility as well.
