A look at where the wind has and hasn’t been blowing over the last three nights
A look into the geographic spread and diversity of wind production over the past three evenings, where we’ve seen supply-demand tightness across the NEM.
wind diversity
Correlation between low wind Capacity Factor and low IRPM (NEM-wide) in recent evenings + Thursday evening looks likely to be low, as well.
Given what’s happened for Monday, Tuesday and Wednesday evening this week (and even tighter supply-demand balance forecast for Thursday evening) we take a look at the correlation between low IRPM and low Capacity Factor across all Wind Farms.
A precis of the ‘Exploring Wind Diversity’ analysis completed in Appendix 27 of GenInsights21
Almost 2.5 years since we released GenInsights21, today we’re publishing this article that contains a precis of the analysis included as Appendix 27 under the title ‘Exploring Wind Diversity’.
Another research paper into solar and wind droughts in Australia
A quick note at another research paper (focused on an area of interest to us) that’s crossed our field of vision.
Instantaneous NEM-wide production from wind on Fri 26th Aug 2022 was lowest in eleven months
Looking back at Friday 26th August 2022 we see that it was not only South Australia that was becalmed. All but one of the wind farms operating in the NEM showed quite low output levels – meaning lowest aggregate level in 11 months!
Updated monthly statistics for NEM-wide wind production
It’s 1st April 2022, and I have not checked these stats in NEMreview v7 for a while, so I thought I would have a quick look at how a number of the key stats are trending: Quick notes about statistics:…
Where’d the wind go, during the last week of April?
Over the week that has just passed we kept noticing production from wind farms across the NEM was fairly muted – so we’ve had a look at what it meant, in aggregate daily capacity factors. This is something we’re exploring much deeper in Generator Insights 2021…
New all-time record Wind Output across the NEM last night (5,430MW at 23:55 on Tuesday 13th April 2021)
David Osmond’s question on Twitter prompted me to have a look at large wind production overnight.
With increasing diversity, the low point of instantaneous aggregate Wind Generation across the NEM is nudging away from 0MW
Patricia Boyce’ challenging question coincided with the low point of cyclic wind output across the NEM this afternoon, and prompted some thinking…
Friday 21st August 2020 sees a new record set for peak and average production across Wind Farms across the NEM
Yesterday (on Fri 21st Aug 2020) we saw a new record set for BOTH daily peak instantaneous output across all wind farms in the NEM, and also daily average output across all wind farms in the NEM.
Trended daily aggregate wind output since January 2010
Prompted by what I’d seen in the (daily) periodic cycling of aggregate wind production recently, I took more of a look at what’s been apparent over time.
AEMO releases its first* ‘Renewable Integration Study’ on 30th April 2020
An article today providing links to the ‘Renewable Integration Study’ which the AEMO released today, and also to the headline media coverage I have seen on my quick scan this morning.
Insights: How do weather patterns impact wind REZ correlations?
RepuTex Energy builds on the Generator Report Card 2018 to provide insights into how different weather patterns impact wind production and the implications for system diversity and portfolio risk.
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”…
Confirmation of yesterday’s supposition that some wind farms are blinking in the face of negative prices
A brief follow on from yesterday’s post, with the advantage of being able to review yesterday’s bids (and rebids) today.
An updated look at daily curtailment of aggregate wind farm output across South Australia
This morning over on Twitter, I was pulled into a discussion that had started with respect to volume of wind energy curtailed in South Australia: The genesis of this twitter conversation was the AEMO’s “Quarterly Energy Dynamics – Q1…
A timely reminder of the need for *much* more diversity in wind harvest patterns
Alerted by our NEMwatch dashboard, I delve into the data and see a scary degree of correlation between the (very low) output of wind farms in south-east South Australia, and (similarly low) output from newer wind farms in northern NSW.
The Southern Annular Mode (SAM) contributes to recent wind drought
An explanation of how the Southern Annular Mode (SAM) contributed to the wind drought we observed recently on WattClarity.
Aggregate Wind Farm output across South Australia topped 1,400MW for the first time – on 9th April, with more to come
Total wind output (aggregated across all wind farms in South Australia) established a new record on Sunday 9th April.
Forecasting is a Mug’s Game
The three main flaws that put boundaries on the usefulness of all forecasting/modelling
