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.
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, if so, to what extent).
Data compilation of the Generator Report Card is underway, given we’ve stepped over into 2019. Here’s a summary insight about the nature of coverage of bound constraint equations across all units in the NEM.
A quick look at AEMO’s current forecasts for Friday (prompted by a few conversations externally)…
Two quick snapshots of a high priced day in Victoria and South Australia – with the price jumping above $12,000/MWh at 15:50
Some thoughts (triggered by the latest wave of focus on “cost” on social media this week) about why we need to rapidly shift our focus to what customers “value” and the market needs.
