The second part of an ongoing case study examining two successive days of low VRE generation in early July 2023. This part examines IRPM, earlier forecasts of available generation and maps the availability by site location.

A brief article as a first Case Study looking at Mon 3rd and Tue 4th July 2023, in conjunction with the compilation of GenInsights Quarterly Updates for 2023 Q3.
A quick look at elevated prices mid afternoon on Monday 3rd July 2023.
A first look at a forecast for tight supply-demand conditions for South Australia on Wednesday 10th May 2023.
It’s taken longer than expected – but today I’ve posted this article that goes some way to answering the question ‘to what extent was solar production disappointing through periods of Q2 2022?’
In this article we take a quick look at how today’s widespread cloud cover is affecting solar production across QLD.
A quick article Monday evening about volatility in QLD.
A quick look into today’s high prices in QLD, and some of the contributing factors.
Geoff Bongers, Nathan Bongers and Andy Boston have prepared this guest authored article following on from their recently published paper about the characterisation and mitigation of renewable droughts in the NEM.
A short note about the start of the evening price spikes on Tuesday 6th July 2021 (these are ongoing, at the time this was posted).
In between other jobs today, we’ve taken a look at why the price spiked yesterday (Tue 20th April) in QLD … at an earlier time than we had become accustomed to seeing it occur in recent months.
Short article today observing higher Scheduled Demand in VIC – which appears to be in large part due to state-wide suppression of solar PV production with heavy cloud and rainfall.
Some quick notes today, to document high-level data (to be explored later) relating to some significantly depressed solar harvest data today due to the widespread cloud/wind event.
Yesterday evening (Tue 9th June 2020) saw an example of ‘dunkelflaute’ across the NEM. It’s a phenomenon we will see increasingly as the transition progresses, so it’s something we should be seeking to understand, and address, with real world solutions and not rose coloured glasses.
Guest author, Allan O’Neil does a masterful job with limited time in reviewing some of the goings-on in the NEM (particularly VIC and SA) on Thursday 30th January 2020
A brief overview of a stressful afternoon/evening in the NEM, where a confluence of events (heatwave-driven high demand, low wind, coal unit trip, etc…) drive LOR2 low reserve condition notice in both VIC and SA, and gear AEMO up to call on Reserve Trader (yet again!)
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?…
Some brief analysis of today’s price volatility seen in the South Australian region of the NEM
