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!)
Two large thermal generating units in Victoria with combined capacity of over 800 MW have recently experienced major electrical faults each requiring many months to repair. Previous WattClarity posts have…
A broader look at what the extended outage at Loy Yang A unit 2 seems to be having on the spot and financial markets into the future, via AEMO MT PASA data, and via the ASX Energy’s futures price data.
Some excerpts from the Generator Report Card to sample some of the analysis we performed to assess various aspects of the ‘dependability’ of coal-fired power stations in the NEM. In this post we highlight availability (or, more precisely, the level of unavailability) as an aggregated monthly volumetric measure trended over 17 years.
Following the notice from AGL Energy on Friday last week about the extended outage occurring at Loy Yang A unit 2, here’s some initial thoughts via WattClarity (with more to come as time permits)
The framework we used to analyse the extent to which coal-fired power is “dependable” in the Generator Report Card, and the extent to which it’s been changing.
Two quick notes about what happened in Victoria on Friday 25th January 2019 following conversations with a number of people.
