A series of articles related to what happened on Tuesday 13th February 2024 … but also the aftermath (in the months afterwards) related to several things, such as:
1) Investigations into what happened, why, and lessons learnt
2) Recovery following the event (in the hours, days, weeks and months) following the event – including:
(a) Returning supply to 100,000s of customers off supply
(b) The repair and return to service of the damaged transmission line
Reflecting on the transmission tower failures in Victoria in February, a group of researchers from the University of Melbourne have put together this summary of what the long-term wind data is showing, and what it means for the power system.

A reader has helped point out that temporary towers brought the Moorabool Sydenham No1 500 kV line back into service on Sun 25th Feb 2024 (with No2 line still out).
AEMO’s preliminary operating incident report for what happened on Tuesday 13th February 2024 is available now.
In light of another transmission tower collapse caused by convective wind gusts, we’ve invited wind loading expert Dr John Holmes to explain this phenomena.
Perhaps unrealised by many, but Tuesday afternoon’s events in Victoria resulted in a new record low in terms of number of coal units being online in the region, Geoff Eldridge explores.
In this article we’ll have a first pass at what happened in Victoria on Tuesday 13th February 2024 at a DI-by-DI level … which we call ‘Timeline #1’ level – noting will go more granular later (Timeline #2) and less granular later (Timeline #3).
An an elevated risk of the contingent disconnection of Distributed PV resurfaces for SA on 15 February 2024 with market notice 114743.
Market notice 114741 cancelled the notice of a high risk of curtailment of distributed PV in SA on 15 February 2024.
What happened yesterday (Tue 13th Feb 2024) in Victoria was a significant event in the history of the NEM – and the flow on effects will be felt for weeks and months (even years?). Here’s a starting list of questions we’d like to explore…
The sixth transmission tower failure within the NEM in almost four years, has prompted further questions about the physical network and its resilience to severe convective winds.
