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.
In Part 4 of this Case Study (with respect to spot price volatility in South Australia on Monday 23rd September 2024) we take a detailed look at the ‘S_PPT+SNPT+BLVR_220’ Constraint Equation, which was particularly meaningful in terms of dispatch outcomes…
On Monday evening 13th January we noted a short-notice ‘Actual LOR2’ in NSW. In this article we take a look at the VIC1-NSW1 interconnector, and particularly the impact of the ‘N::N_MNYS_2’ constraint equation, in limiting the ability of imports from the south to ameliorate.
For several reasons we take a look at a transmission outage in southern NSW that contributed to some volatility seen in QLD and NSW in the second half of May … and might also do in the second half of June 2023.

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