Two different storm warnings in South Australia – one literal, and one metaphorical
Coincidentally this week it seems to me that we’re facing storm warnings on two different fronts – one literal (and much easier to prepare for), whilst the other one is metaphorical and operates at several different levels (and is much, much more difficult to manage).
Navigating the grid – challenges for new solar farm operators

Number crunching begins, for Generator Report Card 2018 (such as with transmission constraints)
Data compilation of the Generator Report Card is underway, given we’ve stepped over into 2019. Here’s a summary insight about the nature of coverage of bound constraint equations across all units in the NEM.
Central Queensland to Southern Queensland flows constrained today
A quick look at the situation today, where generation in central and northern Queensland was constrained down in the middle of the day, driving prices higher.
Crunch Coming–oversupply in northern Queensland?
Some conversations with new generation developers about their prospective developments in northern Queensland has prompted some analysis to help them understand the size of the addressable market for them.
We’re preparing an extensive “Generator Report Card”, and would welcome discussion (with your pre-orders)
Following from (what we have seen as) an increase in diversity of concerns (and claims) about different aspects of generator performance, we’re leveraging our extensive data set and capabilities to have a deeper look, leading to the publication of a Generator Report Card with data to 31st December 2018. We’d welcome input from those who wish to pre-order their copies now at an initial low rate.
A case study in Active Management at a Semi-Scheduled plant – Tuesday 24th July 2018 at Lake Bonney 2 Wind Farm
A detailed look at two specific trading periods in the day (Tuesday 24th July 2018) that saw negative dispatch prices occur at the start of trading periods – hence provided a case study for how existing Semi-Scheduled plant respond (especially in combination with transmission constraints and the Semi-Dispatch Cap).
Reduced exports contributed to reduced prices
Reduced export capability over QNI south contributed to the low prices seen last week.
No, these were not spurious price spikes in Queensland today
Some quick observations about the patterns of volatility seen this week in Queensland
Even Colongra gets a run as high temperatures stretch local supplies in NSW
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.
Two evening price spikes send jitters …
The dispatch price in Queensland spiked to $1,500/MWh at 18:25 and again at 22:40 yesterday evening – triggering jitters in some who fear a return to the volatility of summer 2013.
Updated animation of 20th December 2012 – a volatile day in the Queensland Region
An updated animation of 20th December 2012 focused on the Queensland region – a volatile day for that region.
Animation of several hours over the evening of Saturday 12th January 2013 in Queensland
Here’s another animated case study of one more interesting time that occurred through summer 2013 in Queensland – on this occasion the evening of Saturday 12th January 2013.
Quick quiz – how many do you get right, about what happened in the Queensland Region over summer 2013?
Five thought-provoking questions about what really happened in Queensland over summer 2013 – and the supplementary question about what it all means for the future.
Revisiting 2nd January 2013 in Queensland – to illustrate the interaction of rebidding and constraints
Beginning prior to 7am and progressing through the morning of Wednesday 2nd January 2013, there was significant volatility in the Queensland region of the National Electricity Market – including four spikes at or above $1,000/MWh.
Here’s a walk-through of how it unfolded, with some pointers to some of the contributing factors.
Wild price gyrations in Victoria (and elsewhere) today following a station trip at Yallourn
An animation of 90 minutes this morning where the price gyrated wildly in response to a trip at Yallourn, and numerous subsequent reactions by market participants and the AEMO.
A stinker today in the south – but demand barely wakes from the holiday slumber (and yet prices explode!)

A stinker today in southern Queensland, leading to high demand and prices on the tipping point
A brief look, during the day, of the effect that the Queensland heat wave is having on electricity demand within the state – and further across the NEM. It was a day of marked contrast in demand patterns in the north and the south.
A very volatile day in VIC and SA (not particularly due to the Carbon Tax)
Some quick notes today, on day #2 of the Carbon Tax, prompted by some prices that jumped all around the place (not so much due to carbon, though).
