Patricia Boyce’ challenging question coincided with the low point of cyclic wind output across the NEM this afternoon, and prompted some thinking…
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.
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.
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.
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.
A brief follow on from yesterday’s post, with the advantage of being able to review yesterday’s bids (and rebids) today.
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…
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.
An explanation of how the Southern Annular Mode (SAM) contributed to the wind drought we observed recently on WattClarity.
Total wind output (aggregated across all wind farms in South Australia) established a new record on Sunday 9th April.
The three main flaws that put boundaries on the usefulness of all forecasting/modelling
Some thoughts about the possible uplift to Infigen Energy revenues, stemming from higher forward contract prices in the South Australian region of the NEM
Two slides (from BNEF and AEMO) that provide some context on the energy transition
A starting list of factors that I’d look further into, if I was sucked into the “rabbit hole” of assessing all of the contributing factors leading to the Remarkable Prices seen in Q2 2016 – and which could continue into the future.

Back on 8th October, I spoke at All Energy in Melbourne on this topic. Given the questions posed after the session, it seemed that it might be of value to some WattClarity readers if I narrated over the top of the presentation and included it here, for future reference.
A sped-up animation covering spanning a September 2015 weekend in the South Australian region of the NEM, illustrating both sides of the wind farm output coin.
Some further analysis of different aspects of wind farm output in South Australia
Some back-of-the-envelope calculations being a starting point to help me understand how much real contribution electric vehicles might make in feeding back into the grid when intermittent generation is absent.
