Collections of events that we see happening in the NEM, categorised in terms of the seasons in which they occur.
The run of prices at $0/MWh and below is continuing in Queensland region this week as we pass into spring (many dispatch intervals today down as low as the Market Price Floor at -$1,000/MWh). This begs a few questions…
Without resiling from last week’s criticism of how the headlines from AEMO’s 2019 Electricity Statement of Opportunities (ESOO) were communicated, it’d be churlish for me to fault the depth of disclosure and data sitting behind those results. Literally tens if…
I’d rather not add to the number of conspiracy theories in circulation, but I wonder if there’s a conspiracy to make understanding our electricity system in general, and its reliability in particular, as difficult as humanly possible. There’s no doubt…
AEMO releases its Electricity Statement of Opportunities today, with an initial flurry of press coverage. Another reminder of heightened risk that the NEM is increasingly facing…
Bit of an uncanny coincidence, having posted some concerns about the coming summer 2019-20 only 2 days ago, to find that the AEMO has called for expressions of interest for the Reliability and Emergency Reserve Trader (RERT) Panel across all…
Given the high level of interest in the Generator Report Card, both the Australian Institute of Energy and the Australian Energy Council have organised separate events (in Sydney in August) providing the opportunity to talk through some of the things we’ve learnt through the process of putting the Generator Report Card together. You’re most welcome to attend!
Coincidentally this week it seems to me that we’re facing storm warnings on two different fronts – one literal (and much easier to prepare for), whilst the other one is metaphorical and operates at several different levels (and is much, much more difficult to manage).
Some thoughts about some important questions we should be asking, to follow on from AGL’s announcement last Friday in relation to Torrens A (linked to Barkers Inlet and Loy Yang A2) and also about Liddell.
Two large thermal generating units in Victoria with combined capacity of over 800 MW have recently experienced major electrical faults each requiring many months to repair. Previous WattClarity posts have covered initial assessments of the outages of AGL’s 530 MW Loy…
A few thoughts about the dispatch price being at, or below, $0/MWh for a dispatch interval on Sunday afternoon – implications for the future…
A quick look after the unit trip (including reported explosion) at Mortlake Unit 2
A broader look at what the extended outage at Loy Yang A unit 2 seems to be having on the spot and financial markets into the future, via AEMO MT PASA data, and via the ASX Energy’s futures price data.
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.
