On Tuesday 15th April 2025, the AEMO published its draft report on 'Congestion Information Resource Guidelines', seeking feedback by Monday 19th May 2025.
As the next steps in implementing the AEMC's ISF Reforms, the AEMO has published: (a) on 7th April a consultation; and (b) on 17th April a HLIA.
On Monday 7th April, the AEMO commenced a consultation on the Constraint Formulation Guidelines - which touches on three different changes that some of our readers will find of interest.
A little over 2 weeks ago (on Thu 3rd April 2025) the AEMC made a draft determination on the rule change proposal by Delta Electricity to allow AEMO to accept cash as credit support.
5th article in a series, about the AEMO's ICF0002 initiative (and prior to tomorrow's EWCF Meeting) - to identify some questions and concerns.
As promised in prior articles, here's an illustration of (some of the) different Ramp Trajectories considered in Dispatch within the NEM.
4th article in a series, about the AEMO's ICF0002 initiative - clarifying 2 approaches might (possibly) be explored to resolve.
3rd article in a series, about the AEMO's ICF0002 initiative - and a possible 'solution' being considered (but for which we have concerns).
2nd article in a series, about the AEMO's ICF0002 initiative (re problems with the ~20 second lag in receipt of Dispatch Target).
1st article in a series, about the AEMO's ICF0002 initiative (specifically the content in EWCF meeting on 19th March 2024).
We've facilitated a number of articles on WattClarity relating to the looming FPP changes (now 10 weeks away). Here's two images I've drawn up to (hopefully) illustrate my understanding of what these changes represent.
In his third article, Jack Fox uses the Non Financial Operation (NFO) data to take a look at some VRE units, and how they would have performed under FPP.
In his second article, Jack Fox uses the Non Financial Operation (NFO) data to take a look specifically at batteries, and how they would have performed under FPP.
In his first article, Jack Fox reports some initial observations from a review of the Non Financial Operations (NFO) data that's been published since Dec 2024.
Various authors have shared articles about frequency, frequency control and Regulation FCAS in recent times (including 6 from Linton). Here's three things that jumped out to me in these pieces of analysis.
The faster-moving nature of the FM, with the introduction of FPP, removes predictability in the indicator for frequency performance.
At the end of February 2025, the AER wrote to Semi-Scheduled generators, and other interested parties, warning of the AER’s concerns about self-forecasting practices.
Full financial operation commences 8 June 2025.
The implementation of the Primary frequency response incentive arrangements rule is driving change in how system frequency is controlled and paid-for. The changes stem from how the NEM will incentivise primary frequency response. 6...
