Following a 90-minute period of low IRPM yesterday evening (Mon 17th June 2024) we take a quick look at see forecast low levels of IRPM for Tue 18th June evening (very low!) and Wed 19th June and Thu 20th June.
A short note (in conjunction with some analysis for GenInsights Quarterly Updates for 2023 Q4) about the narrow band of IRPM seen through the day on Monday 20th November 2023.
A short note (in conjunction with some analysis for GenInsights Quarterly Updates for 2023 Q4) about the high level of IRPM seen on Sunday 1st October 2023.
The ‘Australian Energy Week’ conference this week in Melbourne, and the NEM this evening has given a real-time example of some energy transition challenges.
One of the metrics we introduced into GenInsights Quarterly Update for 2022 Q3 was a long-range review of IRPM (Instantaneous Reserve Plant Margin). In this article we share a little of what we found.
NEM-wide IRPM is dropping lower and lower on Thursday 2nd June 2022
A quick look at the supply-demand balance for the QLD on Tuesday evening 8th March 2022 … where it became very, very tight for a period of time (hence very low IRPM).
High temperatures passing through NSW provided the opportunity for the Colongra gas-fired power station to shake off the cobwebs and have a run for the day.
An interesting day in the NEM today, with prices gyrating across a wide spectrum, and across all four mainland regions – on the back of higher demand in Victoria and South Australia due to temperatures there, and supported by transmission issues and other factors.
A graphical summary of a day when temperatures soared in NSW, dragging demand higher and (with the assistance of a relative shortage of supplies) also dragging prices to VOLL
Some preliminary analysis of what happened on Thursday 11th June 2009 – when the NEM experienced its highest NEM-wide demand this winter.
We noted yesterday (Wednesday 10th June) that NEM-wide demand climbed past 32,000MW for the first time this winter.
The following evening saw demand climb to similar levels (a peak of 32,054MW at 18:20 – so 35MW higher than the previous night). However the situation on Thursday night was different in two key ways…
On Wednesday 10th June 2009, temperatures plunged across the NEM for the first time this winter, providing a long-awaited dump of snow to start the season, and driving electricity demand high.
One of 12 articles on the months past in the NEM – in which we examine the trends in price and demand across the NEM for the month of October.
A brief analysis of NEM-wide demand and IRPM during the summer months over the past 4 years.
An illuminating view of the NEM during the high NSW prices on 31st October 2008, illustrated with screenshots and a dynamic video from the new NEM-Watch v8.
Our Managing Director spoke at the “Australian Energy & Utility Summit 08” in
Sydney on Tuesday 22nd July 2008, touching on a number of issues including the depressed prices experienced in winter 2008.
Following from the interest generated in the article published in the AFR, we completed some analysis of the trend in IRPM over the history of the NEM up until June 2007.
The results of this analysis revealed that at no time before 2007 had the IRPM even dropped below 12% and that, except for the 2-day period (19th and 20th June) the IRPM had not dropped below 10%.
