A short article, hopefully (close to) last in the day with this snapshot from ez2view that’s related to a question from a client (GR Case 00006624):
Flagging that there’s appears to have been something that’s gone wrong in NEMDE with the import and/or export limit formulations for (at least) these two interconnectors (i.e. VIC1-NSW1 and the Basslink (i.e. T-V-MNSP1)) as a by-product of all the other things that went awry today.
Paul was one of the founders of Global-Roam in February 2000. He is currently the CEO of the company and the principal author of WattClarity. Writing for WattClarity has become a natural extension of his work in understanding the electricity market, enabling him to lead the team in developing better software for clients.
Before co-founding the company, Paul worked as a Mechanical Engineer for the Queensland Electricity Commission in the early 1990s. He also gained international experience in Japan, the United States, Canada, the UK, and Argentina as part of his ES Cornwall Memorial Scholarship.
Guest author, Allan O’Neil, takes a detailed look at how VIC1-NSW1 transfer capability has been limited frequently due to constraints related to the 051 line in southern NSW, and what it means in terms of inter-regional settlements residue accumulations, market efficiency overall, and the energy transition.
From 16th March 2023 the infamous ‘x5 constraint’ has been split into two. We quickly showed previously that the design of the Left Hand Side (LHS) does not vary. In today’s article, valued guest author Allan O’Neil takes a look at what is different.
In this article we look again at Tuesday 13th February 2024 (Victoria’s ‘Major Power System Event’) and sum up the impact of the event on net exports from Victoria over a 14-hour period, but particularly around ~13:08 when the towers were downed.

The Vic-NSW interconnector constraint equation “allowed” 6,574MW to flow Sth at yesterdays 14:25 DI.
