Following Saturday’s review of changed expectations for Callide Power Station and Yallourn Power Station, I took a look at aggregate expectation by fuel type. Here’s a belated article with the results.
A media release by EnergyAustralia this afternoon (Tue 15th June) about Yallourn mine flooding prompts an updated look on Wattclarity…
A short note about some further delays in return to service for Callide B1 and C3 … though earlier return for B2
Using an in-development (but soon to be released) widget in ez2view we take a look at forecast availability for coal units in NSW, VIC and QLD for the critical, and normally volatile, Q1 period 2021.
Four weeks ago, we observed a significant discrepancy between AEMO’s forecast for (what would have been) a record low point for Scheduled Demand in South Australia and what actually eventuated. We’ve now had time to explore further…
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 rest of the NEM with the trip of the Heywood interconnector.
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 spot prices in South Australia. This analysis is specifically focused on Wednesday 6th November 2019.
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 Daydream Solar Farm on Tuesday 3rd September 2019.
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 this period – Ross River Solar Farm.
The multi-region islanding event on Saturday 25th August was a very rare event – perhaps the only one’s that occurred in the history of the NEM. It has generated plenty of questions – and driven our analysis further. We share some more observations here, and keenly await the draft AEMO report.
On Saturday 2nd September, AEMO responded to a BOM-issued “Severe Weather Event” warning by reducing flow capacity west on the Heywood link. Here’s how that looked…
Tight import limits on the Heywood interconnector and a lull in wind output saw price volatility return to South Australia earlier this week
