Coincident with the AEMC’s Final Determination yesterday (Thu 15th July) on FFR, there was also the Draft Determination published on Energy Storage Systems. Here are some (very) early thoughts…
AEMC Rule Change
A quick note following AEMC publication of final determination on Fast Frequency Response (FFR).
Last week, the AEMO submitted a rule change request to the AEMC for a redevelopment of the ST PASA process (and data sets published – to facilitate what would be a great increase in market transparency).
On Thursday last week the AEMC published a Draft Determination in response to an application by AEC to combat one form of ‘Villain #8’ in relation to Registration of generators under the mandatory 30MW registration threshold.
Following Saturday’s review of changed expectations for Callide Power Station and Yallourn Power Station, I took a look at aggregate expectation by fuel type. Here’s a belated article with the results.
In this article we discuss the 1st of 3 Potential Tripwires that wholesale market participants and others will encounter from October 2021 … with Tripwire #1 coming from the implementation of Five Minute Settlement.
A short article, flagging three potential tripwires we’d like to ensure NEM participants and other stakeholders are aware of in the lead-up to two significant market changes from October 2021.
A quick synopsis of some market reforms at the AEMC relating to system frequency.
Just under 3 weeks ago (on 22nd April 2021) the AEMC published a draft determination that would establish ‘Fast Frequency Response’ as an additional (i.e. 9th and 10th) FCAS service in the NEM. We take a brief look.
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).
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.
