A first (and perhaps only - as this took longer than initially planned) walk through some of the interesting points of what happened yesterday (Sat 16th Nov 2019) when South Australia islanded from the...
There are a number of reasons why we're completing the analysis we are sharing via WattClarity - here are two big ones.
Third case study in a growing series - on this occasion looking at the (extreme - and possibly excessive?) lengths taken by Tailem Bend Solar Farm to avoid being dispatched at times of negative...
Readers at WattClarity might recall that we have asked the question above a couple of times in recent weeks – and a big thanks to those who responded already! We’re blessed with opportunities at...
Lowest point seen today since the start of the NEM (excluding the SA System Black) for the South Australian region.
Our second Case Study in a recent series, aimed to help us explore ways to continue the pushing the development of ez2view forward, but also shared with readers here on WattClarity. This time about...
A quick look at what would have been a new "lowest ever" point for SA Scheduled Demand today at 12;30 ... if the AEMO forecast had held to be valid.
Better late than never (perhaps?) today I post a few thoughts about the AEMC's proposed draft rule change for the incorporation of NegaWatts into centralized dispatch.
An email alert from NEMwatch (noting Scheduled Demand under 500MW in South Australia today) distracts us, and prompts us to dig a little deeper at the longer-term trend.
Thursday 10th October 2019 presented another day of many negative price events in the QLD region. In this Case Study (prepared for dual purposes) we look at how one particular solar farm operated through...
Some operations at Stanwell Power Station unit 1 in the past couple weeks caught our attention, and are presented as a useful illustration of some concepts related to flexibility of power generators (in this...
Last minute complications mean that I cannot speak at today's "Queensland Smart Energy Summit" (with Jonathon Dyson being an even better substitute). Here are some of the observations I would have liked to discuss...
The run of prices at $0/MWh and below is continuing in Queensland region this week as we pass into spring (many dispatch intervals today down as low as the Market Price Floor at -$1,000/MWh)....
Our various dashboard views of the NEM (NEMwatch, ez2view and deSide) have been showing what's seemed like increasing numbers of zero and negative prices in the NEM recently - particularly in QLD. Coupled with...
AEMO releases its Electricity Statement of Opportunities today, with an initial flurry of press coverage. Another reminder of heightened risk that the NEM is increasingly facing...
Two pages taken from our Generator Report Card following several different requests from people who attended different events recently where the Report Card was discussed.
A few additional thoughts about proposed changes to the MT PASA process, informed by our conclusions in Theme 14 within Part 2 of our Generator Report Card.
We've been invited by the Australian Institute of Energy (AIE) to speak this evening in Sydney about some of the lessons learnt in the process of completing our Generator Report Card. Here's some context...
Some brief data gathering and analysis, primarily because I could not resist the exploration, of what might have happened with the load shedding in the electricity grid across England, Wales and Scotland on Friday...
Last week's notable under-frequency load shedding in Great Britain following what appears to be the loss of two generation units in quick succession prompts me to publish some of the analysis of aggregate levels...
