AEMO flags possible intervention tomorrow (Wed 15th Oct 2025) for System Strength in Victoria

A quick scan says it’s probably only happened twice before (24th October 2024 and 13th November 2024), so worth noting two three market notices today (Tuesday 14th October 2025) in relation to tomorrow (Wednesday 15th October 2025).

First there was MN129586 at 12:30 (NEM time):
