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.
wind farm output
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!
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.
A brief look at what’s been happening at Bald Hills Wind Farm – over the 18 months since January 2019, but most particularly in the past couple weeks where output has dropped down near zero.
This is the 3rd of 4 Case Studies to follow on from the main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings). In this case, let’s look at the ‘worst’ case, in aggregate, where wind units under-performed compared to dispatch targets.
Quick notes about a new peak in wind farm output across the NEM that occurred on Friday evening last week (1st May 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.
Considering the extraordinary weather, bushfires, and a couple of large Victorian generators still not back from long term repairs, last week was probably less eventful for the NEM than might…
In what seems (to me) to be an extraordinary measure, AEMO speaks directly to the operators of Wind and Solar assets in the NEM, asking them to update the AEMO on the high-temperature limitations of their plant. How did it come to this?…
A first look back at yesterday (Friday 20th December 2019) in the Victorian region – where we saw extreme temperatures, high demand across VIC and SA and (perhaps because of high temperatures) a large discrepancy open up between forecast Wind Availability and actual. This would have contributed to the surprise LOR2 announcement and commencement of RERT negotiations.
Took 2-3 times longer than planned (as there were a few different interesting observations that came out) but here is our initial – and perhaps only! – review of what happened in South Australia on Thursday 19th December 2019 (i.e. yesterday).
Returning to the challenge posed to readers in April 2019, to guess (or analytically determine!) which of the hundreds of units operating in the NEM showed such a severe limitation in output at high temperatures. It’s not what most people thought it was – far from it!
