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.Read More
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 on the SA grid.
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
AEMC proceeds to fast-track consideration of the AER’s semi-scheduled generator dispatch obligations rule change
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).
Striving to understand the underlying challenges with Semi-Scheduled generators (re AER Issues Paper)
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.
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 a surprise, as our prior analysis suggests the current approach is not sustainable or scalable.
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 Demand in the NEM 2.0 world.
Guest author, Allan O’Neil tries to piece together further detail of what is intended with the apparent tightening of the Reliability Standard (which has sat at 0.002% USE for many years).
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.
Perhaps missed amongst all the bushfire-related action in the NEM, the SA Minister for Energy last week initiated the Retailer Reliability Obligation. Guest author Allan O’Neil tries to come to grips with what this means, and what happens next?
Guest author, Tom Geiser, discusses the different approaches to loss factors amid recent market proposals.
Guest author (and power system control specialist), Kate Summers, looks at what’s changed since she published a paper on frequency control in the NEM back in January 2017.
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.
