A quick note to alert our readers that the ESB has published an Options Paper today on the post 2025 Market Design (with submissions due Wed 9th June 2021).
AEMC Rule Change
This morning the AEMC has published its final rule focused on clarifying how Semi-Scheduled generators should follow dispatch targets – including in dispatch intervals where prices are negative, and some had been unexpectedly switching off.
A recent development over in the WEM (paying energy users to consume, when there’s too much solar and wind) highlights the lack of foresight in the NEM … where we’ve implemented a significant reform (yet to start) that will do nothing to address negative prices.
Today (Thu 19th Nov 2020) the AEMC published a draft ruling following the AER request for a rule change relating to Semi-Scheduled generators … which itself followed from two COAG Energy Council requests to them
A brief note to inform readers that the AEMC is fast-tracking consideration of the AER’s Proposed Rule Change on Semi-Scheduled assets … but also to reinforce our view that the challenge is MUCH broader than is being addressed here.
Following the consultation process conducted by the AER (stemming from their Issues Paper 3 months ago) the AER has today submitted a rule change request to the AEMC relating to Semi-Scheduled generation.
This morning (Mon 7th Sept 2020) the ESB released its Discussion Paper into the design of NEM 2.0 – with 7 different work streams suggested (and submissions due 19th October 2020).
Following on from Friday’s article (which considered the AER Issues Paper) this article delves into more detail of those extremes of ‘Aggregate Raw Off-Target’ across all Semi-Scheduled units that have been recorded over the past 10 years. There’s a clear clustering of cases in 2019 – what does it mean?
Prompted by the recent AER Issues Paper (submissions on that due today – Friday 24th July) but also aware that I’ve not yet published some broader thoughts in response to the ESB’s requests for input into their Discussion Paper on the Two Sided Market concept, I’ve posted some further thoughts. These have been informed by a longitudinal analysis of Aggregate ‘Raw Off-target’ values across all Semi-Scheduled plant.
Here’s an attempt to translate the concern underlying the AER Issues Paper into ‘plain English’ via the popular song.
It’s not a surprise to me to see that someone (the AER in this case) has released an Issues Paper canvassing options for changing the way Semi-Scheduled generators interact with the dispatch process. Not a surprise, as our prior analysis suggests the current approach is not sustainable or scalable.
My understanding is that the AEMC’s Final Rule relating to the push to implement a ‘Negawatt Dispatch Mechanism’ will be released in the morning. I wonder what the implications will actually turn out to be…
A brief note about the (also short) notice from the AER relating to two rule change proposals which it has been asked to propose by the COAG Energy Council
Two earlier articles today prompt this follow-on piece, specifically focusing on what’s being requested by ERM Power in two separate rule change requests relating to the MT PASA process.
The ongoing (second) outage at Loy Yang A unit 2 is a timely reminder of the need to progress the 2 rule change proposals submitted by ERM Power with respect to MT PASA data duration, and granularity.
Guest author, Tom Geiser, discusses the different approaches to loss factors amid recent market proposals.
Better late than never (perhaps?) today I post a few thoughts about the AEMC’s proposed draft rule change for the incorporation of NegaWatts into centralized dispatch.
A few additional thoughts about proposed changes to the MT PASA process, informed by our conclusions in Theme 14 within Part 2 of our Generator Report Card.
Some thoughts from Derek Chapman, from Adani Renewables, in conjunction with two rule change requests at the AEMC relating to Marginal Loss Factors.
Last week the AEMO released a draft of the Marginal Loss Factors (MLFs) that would apply to both generation and loads connected to the NEM. This page on the AEMO…
