A quick look at demand, wind and solar forecasts, along with the constraint invocation schedule in SA for this coming Wednesday, where the AEMO currently have an extended forecast LOR2 condition projected.
Alice Matthews examines how approval times for renewables vary widely by state and technology — with NSW wind projects facing the longest delays.
If we had been in the previous financial year, the old CPT of $1,573,700 would have been tripped.
Spot price volatility occurs in SA on 2 July 2025, yet not to the level that risks exceeding the cumulative price threshold.
Wild storms over night have impacted parts of the Ausgrid, Endeavour and Essential Energy distribution networks in NSW.
After an extended burst of high prices last night, and a short burst this morning, the cumulative price in SA has moved closer to CPT territory.
Cold winter conditions in NSW have pushed market demand in the region above 13GW this evening. Meanwhile, high prices have stuck around in SA.
Under the new direction proposed, netting off would be applied to allocate IRSR. The proposal is open for feedback until 10 July 2025.

For those interested in ‘what happened, why and what should be done about it’ with respect to the 28th April 2025 blackout on the Iberian Peninsula, ENTSO-E is also investigating.
On Wednesday 18th June 2025 Red Eléctrica (REE) published on the “Blackout in Spanish Peninsula Electrical System on 28th of April 2025” .
Earlier today we wrote about the ‘News Release on the blackout on the Iberian Peninsula...’. Here's the report (which we could not find at the time).
Rainfall and cloud cover has split Australia this autumn, delivering a mixed bag of solar irradiance conditions for solar farms across the NEM.
A sequence of afternoon intervals stand out because the forecast appeared to be biased low – self-forecasts suddenly dropped roughly 30-40 percentage points and then increased a short time later.
Theoretically, if a self-forecasting system never offers forecasts for more than 60% of intervals it may perpetually skip the performance assessment and the system could continue for use unsuppressed.
In another style of biasing a self-forecast, "lunar megawatts" represent an expectation of solar farm generation at night when it really should be zero.
The forecast differences would contribute to improved lower RMSE and MAE scores, relative to AWEFS_ASEFS, in the weekly performance assessment.
