Collections of events that we see happening in the NEM, categorised in terms of the seasons in which they occur.
Following the notice from AGL Energy on Friday last week about the extended outage occurring at Loy Yang A unit 2, here’s some initial thoughts via WattClarity (with more to come as time permits)
A large block of green (signifying wind) in our NEMwatch dashboard this morning prompts a look at what the all-time maximum production is these days…
Guest author, Allan O’Neil, drills into considerable depth to understand, and clearly explain, some of what happened during a volatile period in the VIC and SA regions on Friday 1st March 2019
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.
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.
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.
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. Queensland and Tasmania experienced small patches of high prices yet…
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.
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.
