This 18th Case Study in the series investigates two separate dispatch intervals showing extreme collective under-performance across all Semi-Scheduled units on Monday 25th March 2019.
A quick look at this dispatch interval – as the 17th Case Study in the series looking at extreme results for Aggregate Raw Off-Target for all Semi-Scheduled DUIDs.
This is the 3rd of 4 Case Studies to follow on from the main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings). In this case, let’s look at the ‘worst’ case, in aggregate, where wind units under-performed compared to dispatch targets.
A large block of green (signifying wind) in our NEMwatch dashboard this morning prompts a look at what the all-time maximum production is these days…
Guest author, Allan O’Neil, drills into considerable depth to understand, and clearly explain, some of what happened during a volatile period in the VIC and SA regions on Friday 1st March 2019
Yesterday I noted what appeared to be trips of two solar farms – Gannawarra and Karadoc – within a single dispatch interval and coincident with a period of volatile prices. Also yesterday, Dylan McConnell flagged a drop in output at the brown coal plant around the same time, with some questions. With the benefit of access to yesterday’s bids, today I have a look at the 5 power stations (pending a broader review next week by guest author, Allan O’Neil).
Some quick notes about the volatility seen in the NEM on Friday 1st March 2019 – a hot day in Victoria and South Australia, the first day of Autumn.
