File creation times for P5MIN drop, prior to the end of the Market Suspension
Now that we’re past Market Suspension, we take a look back and see file creation latency improve prior to the end of Market Suspension.
File creation times at AEMO for DISPATCHIS and P5MIN increase 50%, coincident [CAVEAT] with Administered Pricing and Market Suspension
In parallel to the ‘Energy Crisis 2022’ (and perhaps related to it, in some ways) we see a step change decline in the performance of the timeliness of file creation for P5MIN at the AEMO in recent days…
Updated (and extended) latency statistics for P5MIN file creation at the AEMO
Following the article on Tuesday 15th February about ‘blow-out in file creation latency’, in this article we update stats for the past week … but also look as far back as late 2018 to see a broader pattern.
NEMDE under strain? Escalation in File Creation times for P5MIN

A short article (in the midst of GenInsights21 completion) more broadly sharing 2 good news stories from AEMO in the context of the NEMDE dispatch process.
Ongoing file creation delays in P5 predispatch data at AEMO
Another set of ‘file creation’ data for the P5 Predispatch prepared by one of our team yesterday (Monday 15th November) suggests the file creation latency issues we highlighted in August are ongoing.
Initial look at the latency of all rebids
Following from some analytical work performed in testing for Five Minute Settlement, here’s a view of latency of rebids (all DUIDs, all commodities) in recent months that prompts a number of questions…
Do you know what’s causing some increased latency on P5MIN data files on MarketNet in recent weeks (Potential Tripwire #4)?
