off-target
Extensive review of Units Off-Target, as part of Generator Report Card 2018
Some brief analysis, on the sidelines of our data gathering for the Generator Report Card 2018, looking at the changing incidence of Aggregate Absolute Off-Target for DUIDs across the NEM.
[UPDATED] Off-Target #4 – Disregard Targets – Lake Bonney in July 2018 (and possibly others)
Two examples where units (in these cases Semi-Scheduled) appeared to disregard dispatch targets.
Off-Target #3 = Forecasting Output Difficult – Macarthur WF on 11th August 2018
One example of where forecasting wind output seemed to be more difficult than we would hope it could be. Something to be further explored in the Generator Report Card.
Off-Target #2 = Unit failed to start – Braemar A3 on 29th August 2018
One example of a thermal unit failing to start. We will endeavour to explore how often this happens as part of the Generator Report Card 2018.
Off-Target #1 = Unit trip – Mt Piper Unit 2 on 24th October 2018
Highlighting one example of a unit trip. We expect we will find many in the process of compiling our Generator Report Card 2018 – the bigger question being whether the incidence is increasing (and, if so, to what extent).
