The north Queensland deluge cuts solar production
A quick look at the effect that the monsoonal rains in northern Queensland are having on several power generation options in northern Queensland.
Looking backwards over the past 2 weeks in the NEM
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.
My first look at the highs, and lows, in Victoria and South Australia on Thursday 24th January 2019
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
AEMO dispatches Reserve Trader on Thursday 24th January as IRPM in VIC and SA plunges
A short post, prior to further analysis next week, to notify readers that Reserve Trader has been dispatched today.
NEM Scheduled Demand tops 33,000MW and prices spike in the south on Tuesday 22nd January
Some snapshots from NEMwatch recording a day where NEM-wide demand breached 33,000MW and prices spiked above $1000/MWh in VIC and SA
First scorching summer day for the year and the sky rocketing price of electricity.
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…
NEM spot prices remained stubbornly high in 2018 – what were the drivers?
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. The underlying reasons for the rise are well understood and…
A potentially extreme temperature forecast for Adelaide and Melbourne next week…
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.
Hot weather forecast to drive demand past 31,000MW next Tuesday 15th January
With high temperatures forecast to return to the NEM next week, we take a quick look at the AEMO’s demand forecast.
Extensive review of Units Off-Target, as part of Generator Report Card 2018
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.
[UPDATED] Off-Target #4 – Disregard Targets – Lake Bonney in July 2018 (and possibly others)
Two examples where units (in these cases Semi-Scheduled) appeared to disregard dispatch targets.
Off-Target #3 = Forecasting Output Difficult – Macarthur WF on 11th August 2018
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.
Off-Target #2 = Unit failed to start – Braemar A3 on 29th August 2018
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.
Off-Target #1 = Unit trip – Mt Piper Unit 2 on 24th October 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).
Number crunching begins, for Generator Report Card 2018 (such as with transmission constraints)
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.
NEM Summer Outlook 2018/19 – what is AEMO saying?
Following on from Paul’s article on Queensland, this post examines the summer outlook for the other mainland NEM regions, drawing from some key AEMO publications and datasources, namely: the Electricity Statement of Opportunities (ESOO) published in August this year AEMO’s Summer…
High temperatures (and high demand) forecast for QLD this Friday
A quick look at AEMO’s current forecasts for Friday (prompted by a few conversations externally)…
How To Reduce Electricity Costs – Part 4
In Michael’s fourth article of the series, he looks at the power of analysing electricity usage data to understand where and when users consume electricity so that they can identify cost saving opportunities.
Dispatch Price spikes above $12,000/MWh in VIC and SA today
Two quick snapshots of a high priced day in Victoria and South Australia – with the price jumping above $12,000/MWh at 15:50
Villain #5c – too much focus on COST, not enough focus on VALUE
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.
