In NSW, the risk of breaching interim reliability standards has risen since August because of the delay to the Kurri Kurri project, but AEMO said reliability remained within interim standards in both the next two summers after Liddell closes. After Origin’s Eraring plant closes in August, reliability breaches the lower interim threshold but does not breach the higher reliability standard until 2027-28 thanks to the 700MW Waratah battery.
Dr McConnell also questioned the finding about the lack of impact of the Snowy 2.0 delay, saying that basing the reason on the transmission timing meant that that finding was due to the modelling approach rather than anything else.
