Whilst not reaching the heights of curtailment of Semi-Scheduled Large Solar, on Sunday 1st September 2024 curtailment of Wind yield across the NEM reached as high as 54%.
Stratospheric warming over Antarctica may have helped bring about the extended period of strong winds in the southern NEM regions.
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 and rise of rooftop PV.
For a couple of reasons, I’ve updated/extended the trend of monthly aggregate statistics for wind farms across the NEM … now out till the end of August 2023.
In this article we explore the impacts on wind power generation as the storms passed through, in the leadup to the transmission line trip at 16:39 (NEM time, reflected in the market by the 16:45 interval) on 12 November 2022.
An updated longer-range trend of monthly aggregate wind statistics (MAX, AVE and MIN per month) to 31st May 2022 … incorporating the new all-time record.
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:…
Following from the release of GenInsights21, in this article we look at some of what that analytical publication can help us understand, in terms of how the changing market is impacting on the role that renewables will increasingly play in the NEM in the years to come.
As Q2 2021 unfolded, it seemed that there were many instances where prices spiked during evening demand peaks – and that wind output was low at the time. So I took a closer statistical look…
The all-time record for ‘peak wind’ continues to climb, with a Sunday evening contribution pushing it higher again.
A quick look at monthly stats shows that, whilst it’s been blowing a gale in SE Australia in recent days, it’s not yet set a new ‘peak instantaneous wind farm output’ record.
Last night, in addition to the dramas unfolding in the QLD region, we set a new record for coincident NEM-wide wind production – eclipsing the prior record from exactly 6 weeks ago.
Which wind farms performed best in 2020? Marcelle extracts data from the GSD2020 to compare spot (and LGC) revenue, and FCAS cost performance, across wind farms in the NEM.
Looking back at Tuesday 13th April 2021 – a day in which the ex-tropical cyclone Seroja in Western Australia caused some wobbles in rooftop solar PV output in South Australia.
David Osmond’s question on Twitter prompted me to have a look at large wind production overnight.
An unfortunately timed significant slump in output across all Wind and Large Solar plant in NSW was another of the factors contributing to the price volatility seen in NSW last week.
In a sneak preview of part of next Thursday’s Clean Energy Council webinar, Marcelle compares the spot revenue performance of wind farms across the NEM.
Some SMS alerts notified me of some volatile dispatch intervals this evening in mainland regions. So I took a quick look…
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.
This is the 12th Case Study in this series (looking at each of 98 extreme incidents). This one is simpler than the 11th Case Study!
