Via an update on LinkedIn from NSW Energy Minister, we’ve become aware of this update on the NSW Government website ‘Update on NSW Government response to power outage in Far West NSW’.
ElectraNet are reporting that at least twenty-three transmission towers and six 132kV stobie poles fell down or were damaged during last night’s wild weather.
Given recent events, we’re asking a rhetorical question about how many temporary transmission towers there are currently in Australia?
On Thursday evening 17th October 2024, a significant weather event in South Australia has damaged the high-voltage network in SA Far North (and power supply has been impacted).

On Friday 28th October, the AEMO released its preliminary report into the storm damage to Liapootah – Palmerston 220 kV lines (loss of more than 500MW of load, and trip of Basslink and multiple generators)
Third article on what happened on Friday 14th October 2022 – sharing a photograph of the damaged transmission (thanks to TasNetworks for the photo, and Zeus for the weather) and outlining a number of different timescales that could be considered with respect to this event.
On Friday 14th October we saw a significant system event in Tasmania – with storms downing power links, leading to large (530MW) loss of load and trip of Basslink. In this article we take a first look at the sequence of events…

Second article today, focusing on what happened late in the afternoon and into the evening in South Australia.
In part 5 of this expanding Case Study of the unexpected price spike on Tuesday 13th Oct, linked to a large & sudden drop in output across 10 solar farms, we take a detailed look at the constraint set ‘Q-BCNE_821’ invoked to deal with the transmission outage between H11 Nebo (in ‘North’ zone) and H10 Bouldercombe (in ‘Central-West’ zone)
In part 3 of this expanding Case Study of the unexpected price spike on Tuesday 13th Oct, linked to a large & sudden drop in output across 10 solar farms, we dig deeper to explore… including wondering whether it would have been expected in advance.
Three main factors contributed to the spot prices in Queensland dropping underwater today for a number of hours – with some factors suggesting this might be the pattern for the coming week…
