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.
Guest author, Tristan Edis, takes a look at the changing pattern of generation by fuel type in 2018
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
A short post, prior to further analysis next week, to notify readers that Reserve Trader has been dispatched today.
Some snapshots from NEMwatch recording a day where NEM-wide demand breached 33,000MW and prices spiked above $1000/MWh in VIC and SA
The first day of scorching summer temperatures for the year has been matched with elevated electricity prices in New South Wales, Victoria and South Australia for most of the day. …
The surge in NEM spot prices since 2015, and related impacts on contract and retail prices, have been extensively discussed and analysed in many forums, from ACCC inquiries to Twitter….
Following AEMO’s warnings issued yesterday about possible extreme heat next week in Adelaide, Melbourne and Sydney, I take more of a look at what might transpire and compare it to historical correlations between cities.
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.
