Initial Review of price volatility in NSW in early afternoon Friday 6th December 2024
For several reasons, we’ve reviewed some afternoon volatility in NSW on Friday 6th December 2024.
‘N-MNYS_5_WG_CLOSE’ constraint set
A collation of articles about the ‘N-MNYS_5_WG_CLOSE’ constraint set, which is an outage-related constraint set in place because there is an ‘outage of the Marulan – Yass (5) 330kV line [with Wagga-Yass 132kV parallel lines CLOSED]’
Amongst the (many) constraint equations that are members of this set is the the ‘N::N_CTMN_2’ constraint equation
Here’s a few things to watch, w.r.t. the forecast tight supply-demand balance in NSW (and QLD) for early next week
In this article on Wednesday evening 20th November 2024 we suggest a couple factors to keep an eye on, leading into the expected tight supply-demand balance (and possible load shedding) in NSW on Tuesday 26th November 2024.

A much shorter run of evening volatility in QLD and NSW on Friday 8th November 2024
There were not as many SMS pings on Friday 8th November 2024 as there were for price alerts the day before, with the only 4 dispatch intervals in QLD and NSW above $1,000/MWh.
Three dispatch intervals (sampled from a long run of volatility on Thursday 7th November 2024) to illustrate the complexity (and significance) of congestion
We’ve selected three dispatch intervals through the long run of volatility in the QLD and NSW regions on Thursday 7th November 2024 to help illustrate:
1) How the issue of ‘congestion’ or ‘constraints’ in the NEM is so complex;
2) But also why it’s so significant to price and dispatch outcomes.
