The AEMO has published its preliminary report into the suspension of the NSW spot market on 23 March 2026 — an event triggered by a SCADA-related issue that interrupted normal dispatch and pricing processes.
On Monday 1st December 2025 (after it was flagged in some media articles) the AEMO released its 154-page '2025 Transition Plan for System Security'.
Back in July 2025 we saw the AEMO had released this ‘Technical Review of the NEM Frequency Control Landscape’ … but are only noting this here now.
As the technologies underpinning the power system change, so too must the approach to supporting system restart.
Eight days after the event occurred, on Friday 13th September 2024 the AEMO published this ‘Preliminary Report: NEM Market Suspension on (Thursday) 5 September 2024’.
