Drop in NEM mainland frequency on Friday 18th October 2024 following trip of Loy Yang A2

It’s been an ‘interesting’ couple of days in the NEM.

Adding to the mix is this frequency disruption just prior to 13:31 (NEM time) on Friday 18th October 2024:

The minimum we can see in our records was down at 49.841Hz at 13:28:45.109 … so just outside the NOFB.

This notes the trip of Loy Yang A unit 2 in the 5 minute period to 13:31.
