Following yesterday’s dust storms, today’s rain (and hail) also sweep through NSW to dampen production from solar farms – small and large.

A brief (initial?) look at the impact of yesterday’s dust storm on the output of NSW large-scale solar farms – particularly Nyngan Solar Farm
Two earlier articles today prompt this follow-on piece, specifically focusing on what’s being requested by ERM Power in two separate rule change requests relating to the MT PASA process.
The ongoing (second) outage at Loy Yang A unit 2 is a timely reminder of the need to progress the 2 rule change proposals submitted by ERM Power with respect to MT PASA data duration, and granularity.
Another weekend reviewing progress on the Generator Statistical Digest 2019 (nearing completion) and I thought it would be of interest to share some insights about Loy Yang A unit 1 that jump of the sample page provided to us in yesterday’s draft.
All I have time to do today, looking into more detail of what happened today …. but note that the challenge is still unfolding.
A quick summary of what’s just happened this afternoon (15:10) with the separation of VIC-to-NSW interconnector due to bushfires that have been plaguing the NEM this summer…
A quick article with the unfolding situation this afternoon in Victoria – tight supply/demand balance, price spike to the Market Price Cap, and RERT negotiations ….
A short note looking at forecast for Victoria today, Monday 30th December (coincidentally as Loy Yang A2 came offline on Friday evening).
With the return of Mortlake unit 2 this week, we take a quick look at current forecasts for the week and quarter ahead in Victoria.
Merry Christmas to Innogy, with first operations seen at the first phase of the Limondale Solar Farm
Noticed that Loy Yang A2 is back online today, so worth a short note.
In what seems (to me) to be an extraordinary measure, AEMO speaks directly to the operators of Wind and Solar assets in the NEM, asking them to update the AEMO on the high-temperature limitations of their plant. How did it come to this?…
A first look back at yesterday (Friday 20th December 2019) in the Victorian region – where we saw extreme temperatures, high demand across VIC and SA and (perhaps because of high temperatures) a large discrepancy open up between forecast Wind Availability and actual. This would have contributed to the surprise LOR2 announcement and commencement of RERT negotiations.
Took 2-3 times longer than planned (as there were a few different interesting observations that came out) but here is our initial – and perhaps only! – review of what happened in South Australia on Thursday 19th December 2019 (i.e. yesterday).
Taking a quick look at what’s forecast for the Victorian region tomorrow, with LOR2-level Low Reserve Condition forecast.
With Queensland temperatures (even at the Brisbane airport) exceeding 40 degrees Celcius today, the electricity demand was also high – though still below the all-time record.
42 months after I posted some initial thoughts about “the opacity of rooftop PV” it seems that – when viewed in certain ways, discussed here – the problem is actually getting worse, not better.
Four weeks ago, we observed a significant discrepancy between AEMO’s forecast for (what would have been) a record low point for Scheduled Demand in South Australia and what actually eventuated. We’ve now had time to explore further…
With summer 2019-20 fast approaching, we’ll use the refresher on the two core components of risk (probability and consequence) to unpick what the real issue is with respect to concerns about overheating electricity supplies this summer, especially in the Victorian region.
