With the benefit of more data available today, can piece together why there was the sudden drop into LOR2 territory on Saturday 1st February 2020 (something that alarmed me, and resulted in AEMO directing a participant to make capacity – just withdrawn – available again).
I’ve snuck into the office on Saturday to start the process of piecing together some of of the different aspects of what happened yesterday to follow on from Friday evening’s short article (this will take quite a while to do…
Today (Fri 31 January 2020) saw NEM-wide demand reach levels never seen before (excepting 29th January 2009). This was just the start of the white knuckle ride.
Published at 12:02, this is a view looking forward to the expected (very high) peak in electricity demand across the NEM this evening.
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.
Comments by the Brett Redman (CEO of AGL Energy) about the poor performance of Liddell Power Station, as reported in the media, prompted me to open up the Generator Statistical Digest 2019 to have a quick look.
Using the (hot off the press) Generator Statistical Digest 2019, we take a look across all 304 DUIDs to see how they performed through calendar 2019 in terms of large excesses in ‘Raw Off-Target’ in both directions. These results suggests implications for the future…
We’ve been appreciating the early orders flowing in from those who did not wait until the release of the GSD2019, and we’re pleased to announce that this new Statistical Digest is available today.
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.
A quick 2nd article today looking at how Reserve Trader was dispatched (and a couple other complexities)
Not looking crash hot for the NSW region this afternoon…
This afternoon saw the Queensland Scheduled Demand peak at 9,657MW – under 400MW off the all-time record set in February 2019.
It was first day back after a couple days away yesterday – and I am mostly focused on completing the Generator Statistical Digest 2019 (for a scheduled release next week, on Tuesday 28th January). Did take some time to quickly…
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
Two earlier articles today prompt this follow-on piece, specifically focusing on what’s being requested by ERM Power in two separate rule change requests relating to the MT PASA process.
The ongoing (second) outage at Loy Yang A unit 2 is a timely reminder of the need to progress the 2 rule change proposals submitted by ERM Power with respect to MT PASA data duration, and granularity.
Another weekend reviewing progress on the Generator Statistical Digest 2019 (nearing completion) and I thought it would be of interest to share some insights about Loy Yang A unit 1 that jump of the sample page provided to us in yesterday’s draft.
All I have time to do today, looking into more detail of what happened today …. but note that the challenge is still unfolding.
