A short record of some large curtailment of Large Solar resource on Saturday 24th August 2024.
Solar Correlation Penalty
Rooftop Solar is crushing* the returns for Large-Scale VRE
Following the release of GenInsights Quarterly Updates for 2023 Q3 we've chosen to share here one of the clear challenges for large-scale VRE that is emerging (particularly in 2023 Q3) due to the rise...
Spot price volatility on Sunday 11th July 2021 – straight out of Angela Macdonald-Smith’s article!
Straight out of the pages of the FinReview and into spot price outcomes in the NEM on Sunday 11th July 2021!
Using the GSD2019 to explore the VALUE of Dispatchability
An article published by AEMC on the 'value of dispatchability' provided the spur to return to our intention of freely sharing insights gleaned from the Generator Statistical Digest 2019. Today's article highlighting the value...
How Good is Solar Farming?
Guest author, Allan O'Neil, takes a look, via the GSD2019 (released today), at the four different headwinds facing solar farm developers and operators operating in the NEM.
Heightened Risk an increasing feature in the NEM these days…
A full page article in the FinReview today quotes a number of people (including our work in the Generator Report Card) speaking about heightened risk in the NEM. Coincident with this, we see another...
Assessing the diversity of intermittent (wind and solar output) as one piece of analysis in the Generator Report Card
In terms of diversity of intermittent supplies, we need to understand that we're not just comparing data series on a scale that runs from "highly correlated" to "random"...
Spot power at $0/MWh in all regions (Sign ‘o the Times*?)
A few thoughts about the dispatch price being at, or below, $0/MWh for a dispatch interval on Sunday afternoon - implications for the future...
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,...
Further thoughts on the emergence of the “Solar Correlation Penalty”
Some further thoughts on what we've termed a "Solar Correlation Penalty" which point-view of some specific dispatch intervals seems to suggest is occurring
The “Solar Correlation Penalty” has already arrived in the NEM
Already we are seeing the highly correlated output of solar PV deliver interesting challenges for the NEM - both to the project proponents themselves, and also to the "everything else" that supplies what's left...
