A first walk through the ‘Q^^TR_CLHA_-600’ constraint equation (at the 10:00 dispatch interval on Monday 3rd March 2025), before 'next day public' data is available.
A second step in the 'Energy Literacy' journey in helping readers to understand the complexities within each and every Dispatch Interval.
This article is a first step into exploring some of the complexities within three of the commonly used time-steps across the NEM.
All I have time to do now is note another change greater than 400MW in a 5-minute period – this time in in Victoria to the 11:10 dispatch interval (NEM time) on Sunday 2nd...
