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...
As promised in the Intermittent Generation Forum late in 2020, the AEMO has released an important Handbook for operators of Semi-Scheduled (wind and solar) assets.
Guest author Allan O'Neil puts together an in-depth explainer about system strength and looks at the current approach to system strength management in South Australia, its impacts and the imminent installation of synchronous condensers...
Following up to AEMO's recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this...
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...
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...
Paul McArdle recently drew my attention to a short Twitter thread started by David Osmond on the arcane topic of NEM system frequency behaviour: At Paul’s invitation I’ve dived further into this issue...
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...
Guest author Stephen Wilson chaired an 'ESIG Down Under' conference webinar on 'Designing the Energy Markets of the Future'. Whilst introducing the session, Stephen presented a diagram that helped to clarify the combination of...
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...
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...
Marcelle digs into the data to find out what the real issues are in the AER's proposed rule change for semi-scheduled generators.
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...
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...
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
Tom Geiser, Senior Market Manager at Neoen, discusses the merits of proportional, relative control on the issue of small solar curtailment.
Recent invitations (from COAG Energy Council and AEMO) prompt some further analysis of the data set assembled for the GSD2019 in order to understand more about one of the challenges in balancing Supply and...
