Tasmania’s grid frequency on Friday 12 April 2024

Posted by Linton Corbet Monday, April 15 2024 Topic: 2024-04-12 loss of load in Tasmania, Autumn 2024 in the NEM

A Trip of 550MW of industrial load in Tasmania on Friday 12th April 2024 represented a sudden loss of a very large fraction of total Tasmanian load.

The grid frequency chart spanning the event highlights three points in time:

  1. At 10:48:52 grid frequency was normal at 50.019 Hz.
  2. The next measurement, 4 seconds later, at 10:48:56 recorded a frequency of 51.233 Hz.
  3. A steady return to 50 Hz was completed by 10:57:12, approximately 8 minutes later.
