Alerted to a price spike at 09:45 this morning in the QLD region, we discovered some reduction in load (spot-exposed Demand Response probably) and also a large collective trip in Solar Farm output (reasons unclear).
Guest author, Allan O’Neil, invests some time to explore a number of different aspects of Easter Saturday (11th April 2020), each noteworthy in their own right (including low demand, high percentage share renewables, negative prices and dynamic bidding)
In order to help us (internally) map out all the different threads to explore in terms of what happened on Friday 31st January 2020 on a remarkable day in the NEM, I’ve identified a few of the key threads here over the weekend. More articles to follow as time permits….
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1st February 2020 (something that alarmed me, and resulted in AEMO directing a participant to make capacity – just withdrawn – available again).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.
Guest author, Allan O’Neil does a masterful job with limited time in reviewing some of the goings-on in the NEM (particularly VIC and SA) on Thursday 30th January 2020
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.
Two quick notes about what happened in Victoria on Friday 25th January 2019 following conversations with a number of people.
Back at work this week and (with curiosity getting the better of me) I have another look at what happened last Thursday and Friday in the South Australian and Victorian regions of the NEM.
A first look at some of the action seen in the southern parts of the NEM on Thursday 24th January 2019 as a result of the latest crazy heatwave that has afflicted central Australia – particularly affecting electricity supply and demand in South Australia and Victoria
A short post, prior to further analysis next week, to notify readers that Reserve Trader has been dispatched today.
Some thoughts by our guest author, about possible reasons why Engie did not bid full output of Pelican Point power station into AEMO on Wednesday 8th February (i.e. the time at which load shedding eventuated).
A look at the supply/demand fundamentals in South Australia and explaining why load shedding was initiated.
Deja-vu all over again in South Australia this evening, with load shedding invoked due to climbing (hot-weather fuelled) demand, and insufficient local generation supplies.
