Late yesterday afternoon the AEMO took the unusual step of releasing a media statement to note that the LOR3 notice for NSW had been downgraded to an LOR2:
“AEMO can confirm that forecast electricity reserves have improved in New South Wales this Wednesday.
As a result, the previously forecast Lack of Reserve Level 3 (LOR3) has been downgraded to a less critical Lack of Reserve Level 2 (LOR2). This improvement is largely due to the cancellation of transmission outages in the region.
AEMO remains focused on maintaining electricity reliability in both New South Wales and Queensland this week, as high temperatures are expected to drive strong energy demand amid significant generation unavailability in NSW.
If electricity supply forecasts deteriorate, AEMO will take all necessary measures, including the activation of off-market reserves, to ensure supply reliability.”
The press release came after several news articles were published earlier in the day – we noted that many of these headlines contained the word ‘blackout’. We’ve collated the list below of all such article that we spotted:
- Tim Foley, of the Sydney Morning Herald wrote Blackout risk: State on alert due to hot weather, coal plant outages
- Peter Hannam, of The Guardian wrote Blackout risk warning as scorching temperatures forecast for parts of NSW
- Tom Saunders and Brianna Perkins, of the ABC wrote Energy market operator warns of potential blackouts across the state, with NSW and Sydney expected to swelter
- Angela Macdonald-Smith, of the AFR wrote Blackout risk lingers in NSW as coal outages hit

Whilst we see that the forecast LOR3 has been downgraded for tomorrow afternoon, forecast LOR2 conditions remain present for long periods over the course of the next 3 days. Meanwhile, as of this morning, we see a new forecast LOR3 condition is now appearing for Thursday afternoon.
Hi Dan – Thursday is looking really tight, with a ~16h LOR2. Curiously, about 5h of that LOR2 is sitting at exactly 0 MW reserve under the latest STPASA. Do you or the WC team have an explanation for what’s providing that balancing – it looks almost to be a market loadshedding mechanism that acts before forced loadshedding?
