A feature of the upcoming EMMS technical specification that distinguishes demand response units from scheduled loads could impact some users of NEM data, if left unmanaged.
A short article, flagging three potential tripwires we’d like to ensure NEM participants and other stakeholders are aware of in the lead-up to two significant market changes from October 2021.
Discussion in a number of different places (including an AFR article today) prompted me to pull some data together of how (spot and futures) prices have trended through 2021, and how they changed with the Callide C4 problems.
This evening I’ve taken a first pass look at how QLD generators bid on Tuesday 25th May 2021, in response to the tight supply/demand balance created by the Callide C4 outage and cascade of events.
A chart we threw together quickly at Beer O’Clock today (from the imminent release of the GSD2020) was worth sharing more broadly on WattClarity today…
Guest author Allan O’Neil provides this handy explainer on how generators’ contract positions affect their bidding decisions and can make negative spot prices pay off, at least in the short term. Very useful for those readers not actively involved in wholesale trading in helping to understand why some conspiracy theories might not match reality.
Walking through 5 (much simplified) “Dispatch Intervals” to illustrate some starting principles of marginal price based dispatch arrangements, such as used in the National Electricity Market
