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...
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...
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...
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...
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...
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...
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...
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...
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.
Two examples where units (in these cases Semi-Scheduled) appeared to disregard dispatch targets.
One example of where forecasting wind output seemed to be more difficult than we would hope it could be. Something to be further explored in the Generator Report Card.
One example of a thermal unit failing to start. We will endeavour to explore how often this happens as part of the Generator Report Card 2018.
Highlighting one example of a unit trip. We expect we will find many in the process of compiling our Generator Report Card 2018 - the bigger question being whether the incidence is increasing (and,...
