A very short article this evening with a single snapshot from NEMwatch v10.2 taken at 19:00, but with the 18:00 dispatch interval the point of interest:
The dispatch price spiked above $14,000/MWh in both QLD and NSW for the 18:00 dispatch interval (i.e. the last dispatch interval in the 18:00 thirty minute trading period). I’m inferring that the subsequent 300MW drop in dispatch target for Scheduled Demand in the QLD region was the result of ~300MW of (spot-exposed) Demand Response in the QLD region … the type which we’ve been serving for what’s approaching 20 years.

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.

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.
Our guest author, Mike Williams, has prepared a review of January and February 2016 in the South Australia – and what it would have meant for energy users with spot exposure, using Demand Response
As many know, Liddell Unit 1 is slated to close today (the last of the 4 units), Friday 28th April. Unfortunately coincident with that, AEMO is forecasting LOR2 low reserve condition for the middle of the afternoon tomorrow, Saturday 29th April 2023.
Returning to the theme of analysis of Q2 prices (completed in 2017 and 2016 due to Q2 historically being an uneventful period) we see that prices have backed off from the “off the charts” level of 2017, but are still much higher in all regions than most other regions. In some cases results are second worst in 20 years.
