One observation about the 2023 ESOO is that EFOR (equivalent forced outage rate) for coal and large gas units is a large and growing challenge.

A quick note on WattClarity to tie in an update (earlier this month) from CS Energy on the rebuild of the cooling tower for Callide C3 and C4.
It does not happen often, so when receiving 4 different ‘coal unit off’ alerts within 24 hours, we thought we would take a look …
Answering a reader question (about the current outage at Millmerran unit 2) with some pictures in an article on WattClarity.
More updates recently about the Callide C power station. Looks like we’ll be waiting a while longer for the (delayed again) return to service…
A short article about a further delay in the expected return to service date for Callide C3 (which is offline after suffering cooling tower failure).
Prompted by a comment by a WattClarity reader, I’ve taken a quick look at Loy Yang A2 for the past week.
A quick look (for Tue 14th June) of which of the coal units are expected to return to service in the coming week.
The EUAA is holding its National Conference this week in Melbourne, and we’re looking forward to being there. Elevated prices (which we have seen a lot of recently) are sure to be part of the conversation…
An initial review of some (wholesale) supply-side factors contributing to the extreme price volatility (and Reserve Trader etc) that occurred in the first week of February 2022 in the QLD region of the NEM.
A quick look at the coal units that are currently offline today in the QLD region, in the lead-up to the tight supply-demand balance.
An updated look at return-to-service expectation for the damaged Callide C4 unit.
Prompted by last Friday’s publication of the AER’s ‘Wholesale Markets Quarterly’ for Q2 2021, here’s a tabulated summary of some of the contributing factors of spot price volatility (and hence high average prices) for the quarter – particularly for QLD and NSW.
On Friday evening (28th May) and again this evening (Sun 30th May) my phone buzzed plenty of times – due to price volatility, and also alerting on low IRPM (enabled with Callide units offline, and low wind harvest at peak demand time).
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.
Following a week where several days saw price volatility in NSW (with this being so extreme that Reserve Trader was triggered on Thursday 17th December) we’ve taken a look at the comparative performance of coal units across the NEM (and particularly in NSW) compared to prior years.
Third day in a row we see volatility in NSW (and QLD) … and this afternoon AEMO contracts, and then dispatches, Reserve Trader in NSW
Some SMS alerts notified me of some volatile dispatch intervals this evening in mainland regions. So I took a quick look…
Guest author, Allan O’Neil does a masterful job with limited time in reviewing some of the goings-on in the NEM (particularly VIC and SA) on Thursday 30th January 2020
A brief overview of a stressful afternoon/evening in the NEM, where a confluence of events (heatwave-driven high demand, low wind, coal unit trip, etc…) drive LOR2 low reserve condition notice in both VIC and SA, and gear AEMO up to call on Reserve Trader (yet again!)
