Operating under siege
We take a look at challenges for AEMO in operating the system under the security threats posed by the ongoing bushfires …
AEMO
The (ongoing!) opacity of distributed, small-scale solar PV output
42 months after I posted some initial thoughts about “the opacity of rooftop PV” it seems that – when viewed in certain ways, discussed here – the problem is actually getting worse, not better.
Exploring AEMO’s demand forecast “error” for Saturday 26th October 2019
Four weeks ago, we observed a significant discrepancy between AEMO’s forecast for (what would have been) a record low point for Scheduled Demand in South Australia and what actually eventuated. We’ve now had time to explore further…
Summer reliability back in the headlines
Guest author, Allan O’Neil, provides us an update today on what we can see about summer 2019-20 (in the physical market, and the financial market), now that it is only just around the corner.
ESOO Unboxing
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…
ConfUSEd by the ESOO? You’re not alone.
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 2019 Electricity Statement of Opportunities – more tinder for the “energy wars” fire…
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…
Summer 19-20 is heating up already, with Reserve Trader called
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…
A twenty year review of Marginal Loss Factors
Last week the AEMO released a draft of the Marginal Loss Factors (MLFs) that would apply to both generation and loads connected to the NEM. This page on the AEMO site links to more details. On that page, the AEMO…
AEMO released 2018 Integrated System Plan (ISP)
A back-dated article about the AEMO’s 2018 ISP
Decoding AEMO’s latest ESOO–will the lights stay on this summer?
Some initial analysis by our guest author, Allan O’Neil, about what AEMO’s Statement of Opportunities 2017 is saying in terms of this coming summer 2017-18
On Saturday 2nd September, AEMO reacted to Severe Weather Warning by imposing limits on interconnector
On Saturday 2nd September, AEMO responded to a BOM-issued “Severe Weather Event” warning by reducing flow capacity west on the Heywood link. Here’s how that looked…
Noteworthy analysis of the state-wide blackout across South Australia on 28th September 2016
A listing of key reports and analysis into the SA blackout of 28th September 2016.
Was South Australia lucky the lights stayed on last Friday?
Last Friday’s events took South Australia much closer to the brink of another Black System event than many seem to have realised
Five fixes for the NEM
Load shedding in South Australia on Wednesday 8 February and successive ‘close shaves’ in NSW and Queensland as the heatwave spread north have exposed serious weaknesses in the national electricity market (NEM).
One example of how price spikes in the physical market flow through to the financial market
Illustrating how the price spike on 14th January flowed through to hedge contract prices.
The opacity of distributed, small-scale solar PV output
A comparison of the output of the two different estimates now available for aggregate state-wide output from small-scale solar PV systems – the ARENA-funded APVI method, and a new method from AEMO
