Today (Wed 15th May 2024) Bruce Mountain writes an opinion piece in the Australian about the recent run of Administered Pricing in NSW, and what it means for the looming closure of Eraring and the energy transition.
ESIG Report ‘New Resource Adequacy Criteria for the Energy Transition’
Last week I was notified of the release of a new ESIG report ‘New Resource Adequacy Criteria for the Energy Transition’, which will be of interest to some WattClarity readers.
Policy implications now and for the transition
The third and final part of this series of articles from Greg Williams about opportunity costs in electricity markets - this time narrowing in on policy implications.
What’s happening around Wagga?
Guest author, Allan O'Neil, takes a detailed look at how VIC1-NSW1 transfer capability has been limited frequently due to constraints related to the 051 line in southern NSW, and what it means in terms of inter-regional settlements residue accumulations, market efficiency overall, and the energy...

Increasing curtailment of Wind and Solar across the NEM
With Q2 drawing to a close, we're gearing up to produce GenInsights Quarterly Update for this quarter. Timely to look back at Q1 at what was reported about curtailment of wind and solar in that earlier Quarterly Update.
An imminent improvement to the bidding and dispatch process for Semi-Scheduled units
AEMO is re-enabling the ‘MaxAvail’ figure in bids for Semi-Scheduled units. It will act as a limit on capacity available, feeding into the NEMDE dispatch process for the unit. We look at how Semi-Scheduled plant have currently been treating MaxAvail in the bid and share...
Too Early to Say?
Guest author, Allan O'Neil, publishes some analysis for WattClarity on price and generation mix changes apparent in the NEM coincident with (but not wholly caused by) the closure of the last remaining units at Liddell Power Station.
Case Study of 17:05 on 27th October 2022 (+861MW AggROT for Semi-Scheduled units) … Part 1 of (an uncertain number)
In Part 1 of this Case Study, we start to look at the large collective under-performance across all Semi-Scheduled units (i.e. Wind and Large Solar) at 17:05 on 27th October 2022. More to come in subsequent parts...
Observation 13/22 from GenInsights21 – is the Semi-Scheduled category sustainable or scalable?
Here on this site, and also in real discussions in the offline world, we have been pondering this question for a number of years. For instance, it was pondered in Theme 13 (‘What’s the future for Participation Categories in the NEM?’) within the 180-page analytical...
The NEMs frequency behaviour – how is it going?
Following recent online discussions, Bruce Miller has produced this in-depth analysis of frequency behavior in th NEM.
