A brief overview of a stressful afternoon/evening in the NEM, where a confluence of events (heatwave-driven high demand, low wind, coal unit trip, etc…) drive LOR2 low reserve condition notice in both VIC and SA, and gear AEMO up to call on Reserve Trader (yet again!)
A quick look (ahead of time) at what looks set to be a very high level of electricity demand right across the NEM tomorrow evening, Friday 31st January 2020. Just in time for the Australian Open semi-finals.
Today I managed to get about half-way (only!) through some analysis I wanted to do to ‘scratch that itch’ about what happened in the NSW Region on Thursday 23rd January – with LOR2 conditions necessitating RERT (Reserve Trader) in the NSW Region.
This afternoon saw the Queensland Scheduled Demand peak at 9,657MW – under 400MW off the all-time record set in February 2019.
Following yesterday’s dust storms, today’s rain (and hail) also sweep through NSW to dampen production from solar farms – small and large.
A brief (initial?) look at the impact of yesterday’s dust storm on the output of NSW large-scale solar farms – particularly Nyngan Solar Farm
All I have time to do today, looking into more detail of what happened today …. but note that the challenge is still unfolding.
A quick summary of what’s just happened this afternoon (15:10) with the separation of VIC-to-NSW interconnector due to bushfires that have been plaguing the NEM this summer…
A quick article with the unfolding situation this afternoon in Victoria – tight supply/demand balance, price spike to the Market Price Cap, and RERT negotiations ….
A short note looking at forecast for Victoria today, Monday 30th December (coincidentally as Loy Yang A2 came offline on Friday evening).
With the return of Mortlake unit 2 this week, we take a quick look at current forecasts for the week and quarter ahead in Victoria.
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 have been expected, but it certainly wasn’t incident-free. A very…
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).
Taking a quick look at what’s forecast for the Victorian region tomorrow, with LOR2-level Low Reserve Condition forecast.
With Queensland temperatures (even at the Brisbane airport) exceeding 40 degrees Celcius today, the electricity demand was also high – though still below the all-time record.
The spot price in Queensland spiked above $1,400 for the first time of the summer on Monday afternoon
Guest author, Allan O’Neil, provides us an update today on what we can see about summer 2019-20 (in the physical market, and the financial market), now that it is only just around the corner.
With summer 2019-20 fast approaching, we’ll use the refresher on the two core components of risk (probability and consequence) to unpick what the real issue is with respect to concerns about overheating electricity supplies this summer, especially in the Victorian region.
