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...
Our guest author Stephen Sproul looks at how the Dalrymple Battery Energy Storage System (BESS), currently the only source of virtual inertia on the NEM, responded to the November 2019 SA islanding event.
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).
A back-dated article, looking back at the two ERM rule change requests which, when passed by the AEMC, had great effect in expanding transparency in the NEM in relation to generator availabilities from 20th...
Using the (hot off the press) Generator Statistical Digest 2019, we take a look across all 304 DUIDs to see how they performed through calendar 2019 in terms of large excesses in 'Raw Off-Target'...
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...
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.
Some thoughts from Derek Chapman, from Adani Renewables, in conjunction with two rule change requests at the AEMC relating to Marginal Loss Factors.
A collection of thoughts that have been bumping around in my head for some time about the latest push by various parties to facilitate a broader range of demand response in the NEM, and...
Guest presenter, Kate Summers, spoke at UoM Climate and Energy College on 15th August 2018, with the presentation recorded. Kate shares this today with WattClarity readers.
A quick look back at the AEMC's Final Determination on Five Minute Settlement.
A belated link to the Finkel Review.
The National Electricity Market (NEM) is designed to operate at 50 Hz. Frequency deviation occurs when generation and load are mismatched. It is important in a lightly meshed and long network such as the...
