It’s now seven months since the SCADA outage on Sunday 24th January 2021 – and we’re finally able to complete and publish this (quite long) article exploring some of the implications for units on the LHS of the ‘Q>>NIL_CLWU_RGLC’ constraint equation
‘Q>>NIL_CLWU_RGLC’ constraint equation
More time has elapsed since ‘Part 3’ on 24th March – today I’m posting a shorter piece (Part 4) that explains how RHS of the ‘Q>>NIL_CLWU_RGLC’ constraint equation drove down output and led to the price spike on Sunday 24th January 2021.
It’s taken a while to find the time – but today I’m posting this next analytical piece (Part 3) that seeks to understand what happened on Sunday 24th January 2021 with the NEM-wide SCADA Failure, which contributed to the price spike that occurred in QLD by virtue of what it did to the ‘Q>>NIL_CLWU_RGLC’ constraint equation.
Two months ago prices spiked in QLD on a Sunday afternoon when AEMO lost SCADA data feed. One month ago AEMO published a preliminary report. In the background we have been taking a look…
