Back in July 2025 we saw the AEMO had released this ‘Technical Review of the NEM Frequency Control Landscape’ … but are only noting this here now.
About 4 weeks ago the 2025 ESOO was released. In this article we highlight 3 x 2 different ways this might be viewed - and note some other dimensions not considered.
Whilst attending day 1 of the CEC’s ‘Queensland Clean Energy Summit 2025’ yesterday we noticed the release of the Climate Risk Assessment, and the Adaptation Plan
A zoomed-out view of six metrics supports understanding of physical/technical semi-scheduled generator availability.
Combining together a bundle of different metrics related to the 'availability' of a wind farm, we take a look at what's happened at Bulgana Wind Farm over the past ~25 months.
In this article, we tie together various events since 1st January 2024 that featured either System Frequency outside the NOFB and large AggROT for Semi-Scheduled assets.
We count the number of days each month when there was at least one 4-second measurement outside the NOFB.
How common is it that mainland frequency deviates outside the NOFB (normal operating frequency band)?
Earlier today we trended the incidence of large Aggregate Raw Off-Target across all Semi-Scheduled units. In this updated tabulated list, we list each of the largest instances from January 2024 to June 2025.
It's ~18 months since we took a look at the trend of large instances of Aggregate Raw Off-Target across all Semi-Scheduled units. In this article we update the analysis with data to 30th June...
System frequency shows improved resilience to sudden coal generation events since 2020.
A count of coal generator events indicates large unit trips are less frequent.
Over the past week (and particularly Wednesday 11th June 2025 and Thursday 12th June 2025) gas-power generation ran strongly in Victoria. So we take a quick look at the historical context.
Winter 2025 has arrived, with a cold front driving high wind production - which prompts this initial look in wind production for 2025 Q2 to date.
Another short article with this trend from the ez2view ‘Trends Editor’ to summarise the overall trend of (monthly average) prices in the 8 x Contingency FCAS markets focused on the NSW region.
47% of dispatch intervals for semi-scheduled solar units are seeing a self-forecast used. When there are gaps, was the unit suppressed?
We summarise how wind units are using self-forecasting to-date. The analysis leads us to consider where upcoming market change may lead the industry.
The introduction of frequency performance payments in 2025 changes how costs of regulating frequency are quantified and allocated. This article inspects historical trends in regulation FCAS enablement levels and prices.
Following on from a similar review this time last year, Dan provides an updated look at the economics and performances within the NEM's big battery fleet, making use of our recently released GSD2024.
With respect to forecasts for peak South Australian ‘Market Demand’ in summer 2024-25 (and particularly with expectations of high demand on Wed 12th Feb 2025) we've provided this article as some context.
