A short article with a snapshot from NEMwatch at 15:45 showing the QLD spot price up near the Market Price Cap, and NSW also above $1,000/MWh:
I particularly noticed the IRPM of the QLD-only ‘Economic Island’ formed by the lack of spare import capability (indeed, limits set so that QNI and DLINK must flow south) down at 3%
This is because of only 300MW of spare Available Generation, by the numbers AEMO published in this dispatch interval. I don’t have time to look at what capacity is unavailable, for it must be a fair amount!
One of three founders of Global-Roam back in 2000, Paul has been CEO of the company since that time.
As an author on WattClarity, Paul's focus has been to help make the electricity market more understandable.
Curiosity drove us to take this initial (and very quick) look at bidding behaviour, NEM-wide, across the past 14 days in relation to recent NEM-wide price volatility.
One of 12 articles on the months past in the NEM. For January we revisit events such as the fires at Moomba in 2004 (which curtailed gas supplies from central Australia); and the blackout on 16th January 2007 which drove the price to VOLL in Victoria.
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%.
