It was spurious, but worth noting that the AEMO published MN145396 at 13:10 (NEM time) on Tuesday - noting forecast LOR3 (load shedding) in South Australia on Thursday morning (1st October 2026).
We’re not the only ones who noticed Akaysha Energy’s announcement yesterday (Monday 28th September 2026) that ‘Waratah Super Battery reaches final commercial operations’.
It’s Monday 28th September 2026, which means we’ve just clocked over 10 years since the SA System Black event (on Wednesday 28th September 2016). Like a number of others have done, here’s our short WattClarity® note to commemorate this.
That 1st of October date for go-live is now inside the ‘ST’ (short term) time horizon. As such, we are seeing the new NSW to SA interconnector included in ST-PASA results.
Yesterday we were involved in a discussion with others about what happened at Tarong unit 2 on Monday 21st September 2026. So we take a short look.
The new ‘lowest ever’ point for 'Market Demand' was down at 9,072MW as Target ‘Market Demand’ for the 12:55 dispatch interval yesterday (Sunday 20th September 2026).
A pre-configured alert from ez2view notified us via the Mobile App that the Templers BESS had come to life again, on Friday 18th September 2026.
In this article we take the AEMO’s 4-second data and present this trace to start a broader sweep of system effects:, starting with System Frequency following trip of Loy Yang A1 near 4am on Monday 7th September 2026.
Because it’s been the topic of some internal discussions since it occurred at 14:40 (NEM time) on Monday 14th September 2026, here’s a quick record of some salient details
I was a still away when (last Friday 11th September) I could not help but notice this update on LinkedIn from Hydro Tasmania that starts with the startling sentence ‘It's been just over a week since a fire destroyed Tungatinah Power Station.’!
Yesterday (Tue 15th Sept 2026) we noticed Significant oscillations in ‘Market Demand’ in VIC, and also saw notable frequency fluctuations. We look at Dispatch Error.
We might return to this later (time permitting) but just wanted to capture these oscillations in ‘Market Demand’ in Victoria on Tuesday afternoon 15th September 2026 – via this NEMwatch snapshot at 13:45 (NEM time).
Earlier, we noted ‘Unit trip at Loy Yang A1 on Monday morning 7th September 2026 (part 1)’. Here we follow that on with two more snapshots from ez2view to look at the outage in a little more depth.
A reader has notified us of a unit trip at Loy Yang A1 unit last Monday 7th September 2026 – so we take a quick initial look at the trip in the 5-minutes within the 04:00 dispatch interval
After Wednesday's first SIPS test, the Waratah Super Battery successfully completed its second this afternoon, as it inches closer to commercial operations.
A short post to note that the Waratah Super Battery tested its full SIPS capacity of 700MW for around two hours yesterday morning — the first time it was able to do this since last October's transformer failure.
Fire has damaged Tungatinah Hydro Power Station in Tasmania, out indefinitely.
Last Thursday 27th August 2026, the AEMC published a consultation paper with respect to ‘Dispatch limits for inverter-based resources’.
We noted a ~500MW jump in 'Market Demand' in Victoria just after 11:00 on Friday 28th August 2026 that was not forecast in advance. We wonder about 'three hours free' effects...
The Stanwell Power Station coal units are some of the best performing coal units in the NEM … which is what made this full-load trip on Thursday 27th August 2026 just prior to 12:00 unusual.
