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…

A quick article highlighting how the trend in aggregate number of unit starts, across the whole of the NEM, highlights the scale of one of the core underlying changes (and challenges) facing us in the NEM’s energy transition.
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 whether there are better options
A note of caution, that Demand Response is not a magic wand – it *can* achieve a lot, but if can’t be assumed to automatically appear to bridge any gap between supply and demand in a market model, for instance.
One more example of not focusing on the real problems seems to be a tendency for some to obsess about one narrow type of Demand Response (i.e. dispatch of NegaWatts) whilst seeming to lose focus of what the overall objective is (a more active and responsive demand side).
Yesterday I noted what appeared to be trips of two solar farms – Gannawarra and Karadoc – within a single dispatch interval and coincident with a period of volatile prices. Also yesterday, Dylan McConnell flagged a drop in output at the brown coal plant around the same time, with some questions. With the benefit of access to yesterday’s bids, today I have a look at the 5 power stations (pending a broader review next week by guest author, Allan O’Neil).
Some quick notes about the volatility seen in the NEM on Friday 1st March 2019 – a hot day in Victoria and South Australia, the first day of Autumn.
In the process of assembling a long-range data set on how much every single generator has contributed to the price of Energy in each Region of the NEM (which we’re doing for our Generator Report Card 2018) we’ve pulled some preliminary analysis together here of how many dispatch intervals since 1st January 2018 see the Price Setter files highlight instances of setting the price ranging:
from “Very Simple” (at Category 1)
… to “Very Complex” (at Category 5)
An AEMO Market Notice about “Generator Recall” for Friday’s forecast hot weather in South Australia and Victoria prompts a quick look at what’s changed in the forecast that would prompt this action.
Taking a brief (well, actually longer than intended) look into the various factors that delivered a price spike above $10,000/MWh on Thursday 31st January in NSW – and thinking through the implications for one particular Demand Response client, and for the broader market.
The Queensland region of the NEM saw a new all-time record for peak electricity demand today (Wed 13th February 2019) by several different measures. A bit later in the evening we take a brief look at a few different factors.
As part of the process of compilation of our Generator Report Card 2018, we’re delving into quite some detail into various aspects of generator bidding and re-bidding. Today I thought it might be useful to share some *very early and preliminary* observations that we’re starting to see when trending and categorising rebids.
Currently (as at Monday morning 11th February) AEMO forecasts indicate that Queensland electricity demand on Wednesday afternoon will come very close to an all-time record.
AGL released its investor presentation yesterday – several people flagged the availability stats within the presentation (they knew we were looking at aspects of reliability for our Generator Report Card 2018). Hence I take a brief detour and have a quick look.
Two quick notes about what happened in Victoria on Friday 25th January 2019 following conversations with a number of people.
A quick look at the effect that the monsoonal rains in northern Queensland are having on several power generation options in northern Queensland.
Back at work this week and (with curiosity getting the better of me) I have another look at what happened last Thursday and Friday in the South Australian and Victorian regions of the NEM.
A first look at some of the action seen in the southern parts of the NEM on Thursday 24th January 2019 as a result of the latest crazy heatwave that has afflicted central Australia – particularly affecting electricity supply and demand in South Australia and Victoria
With high temperatures forecast to return to the NEM next week, we take a quick look at the AEMO’s demand forecast.
Some brief analysis, on the sidelines of our data gathering for the Generator Report Card 2018, looking at the changing incidence of Aggregate Absolute Off-Target for DUIDs across the NEM.
