During yesterday evening’s I posted this snapshot from NEM-Watch v10 on Twitter, highlighting how Scheduled Demand in Victoria was up above 9,000MW – and was likely to remain up there whilst temperatures remained high:
As noted in that chart, the hourly average Apparent Temperature at Melbourne airport remained above 30 degrees until after 21:00 NEM time (22:00 Melbourne time), which suggests some pretty uncomfortable attempts to get to sleep early for those who had to do so (and did not have air-conditioning, or were affected by the distribution-level network outages).
Paul was one of the founders of Global-Roam in February 2000. He is currently the CEO of the company and the principal author of WattClarity. Writing for WattClarity has become a natural extension of his work in understanding the electricity market, enabling him to lead the team in developing better software for clients.
Before co-founding the company, Paul worked as a Mechanical Engineer for the Queensland Electricity Commission in the early 1990s. He also gained international experience in Japan, the United States, Canada, the UK, and Argentina as part of his ES Cornwall Memorial Scholarship.
Two days in a row, the AEMO has issued its first and second alerts (via Market Notice) about forecast Minimum System Load events for Victoria. This second alert for Friday 27th September 2024.
Hot on the heels of Monday evening’s volatility, the AEMO has forecast LOR3 Low Reserve Condition (i.e. load shedding) might be possible in QLD on Tuesday evening.
For only the 5th time in 11 years of NEM history (and the 3rd time for South Australia) four consecutive days of price spikes have forced the Cumulative Price to the Threshold, and AEMO has imposed price caps to prevent retailers from going bust.
Just as had been forecast, Tuesday 13th January 2009 saw hot, dry weather roll in across South Australia, and then into Victoria. The high temperatures caused demand to climb, but not to the level at which NEMMCO had forecast demand to climb over the summer period. As a result we saw the price in SA jump to a level near VOLL at 13:40, and remain there until about 18:00 (i.e. more than 4 hours).
