Transmission Development & Operations
Here we will collate articles (as we publish them, and remember to collate them in here) that relate to various aspects of the role of transmission in the energy transition .
Areas of interest include:
1) Design and construction
2) Operations
3) Outage planning and operations
4) Failure modes and rates
5) How to model transmission.

Pre-PEC gremlins strike … AEMO notes ‘Suspect Lack Of Reserve Level 3 (LOR3) in the SA Region on 01/10/2026’
It was spurious, but worth noting that the AEMO published MN145396 at 13:10 (NEM time) on Tuesday - noting forecast LOR3 (load shedding) in South Australia on Thursday morning (1st October 2026).
PEC Stage 2 enters the ST timeframe
That 1st of October date for go-live is now inside the ‘ST’ (short term) time horizon. As such, we are seeing the new NSW to SA interconnector included in ST-PASA results.
Our current hypothesis, for the strange-looking modelled results in Monday’s MT PASA data, relating to PEC Stage 2
Earlier this week, we looked at the first round of AEMO modelled MT PASA results for the Project EnergyConnect, and had some questions. After some digging, we think we understand...
A first look at PEC Stage 2 in AEMO’s MT PASA weekly data set
I was curious to see how the PEC Stage 2 (i.e. NSW1-SA1) is being represented in the new data sets now appearing in the MT PASA process. Hence this initial view, which prompts questions.
AEMO published final version of go-live plan for Project EnergyConnect
On 7th August 2026, the AEMO published this (final version of) the go-live plan for Market Integration of Project EnergyConnect
Looking back at the South-West NSW RIT-T through a system strength lens
This article from Nadali Mahmoudi and Liam Atkinson from EPEC Group looks at whether the Dinawan–Darlington Point 330kV upgrade, dismissed in 2022, would have delivered greater system strength benefits than what was recognised at the time.

The greatest difference, pre and post July 2025, is in the flows from Victoria to Tasmania.
The *basics* of how Project Energy Connect will appear in NEM Data
We're under 5 months away from the appearance of the new NSW1-SA1 interconnector in AEMO's Market Systems (representing 'PEC Stage 2'). Here's 3 basic principles...
~28 years of history for the VIC-SA interconnector, in one chart
We thought it was useful to power up the ‘Trends Engine’ in ez2view and produce the following time-series trends of monthly statistics of Target Flows, and Limits, over the VIC to SA interconnector over the past 28 years.
Exploring the potential impacts of HumeLink and Snowy 2.0 on the Southern NSW electricity network
This article by Ryan Powell and Nadali Mahmoudi examines how major southern NSW transmission upgrades — particularly HumeLink — are expected to reshape network congestion, and what that means for the operation of Snowy 2.0 once it comes online.
