Following on from my earlier post about my own experiences as a small power generator (with solar PV at home), I’ve taken a broader look at solar PV production NEM-wide, including over the corresponding “stormy weather” period of October highlighted in the prior article.
There’s already been a large uptake of distributed energy generation data, and there promises to be much more to come in this energy transition. With this comes some significant challenges – along with opportunities (with respect to the electricity production itself, and also in terms of the data that’s produced). So in the interest of doing things better, here’s a detailed look at our own rooftop solar experiences at home.
Flagging the ongoing challenge of not extrapolating from recent performance to infer that “things” will always be that way.
The two emergency generators provide first power to the South Australian grid.
My sense is that we, the voting public, are Villains #2 in running the energy transition train off the tracks.
First up in our listing of Villains in relation to the unfolding energy crisis are, of course, our political leaders – State and Federal, past, present and prospective.
A multi-layered energy crisis is upon us. I’ve identified 10 “root causes” (or “villains”) that have each played key roles in the way in which our energy transition has run off the rails.
Quick look at how Gullen Range solar has gone, since it started on 14th September.
Reading an article in the Courier Mail on Saturday I was struck by the use of two particularly odd examples to support a case for retention of government ownership of electricity generation.
Here’s a chronological record of key aspects of government involvement in the generation sector within Queensland.
Some quick thoughts about the comparison being made by others between two ageing coal-fired power stations (Liddell power station in NSW and the Muja A&B stations in the SWIS of WA)
Our first look at trended LGC production (aggregated by state/territory) and LGC spot prices (monthly average), now possible in NEMreview v7, generates a number of questions…
It was inevitable that Semi-Scheduled plant would start to experience times when they are dispatched down. It’s a big prompt to take next steps up the learning curve.
One of the challenges in analysis is to even be conscious of the need to ascertain “what might have otherwise been”.
An article that sums up some decidedly un-quick calculations we’ve performed – looking over an 8 week period to 13th September to estimate how much wind power has been curtailed by the AEMO.
A quick look at the scale of the challenge, if Mt Piper were to be forced to close following a court challenge to coal supplies upstream
The wholesale cost of electricity has risen (too fast, too high) in recent years. However let’s not let ourselves be conned into believing that this has arisen, now, because of the creation of the NEM back in 1998.
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…
From one extreme (perhaps lowest ever in June 2017, on like-for-like) to the other (new record production) in the space of just one month for aggregate wind in South Australia
Some thoughts about challenges with intermittent solar PV, triggered by this week’s Solar Eclipse in North America
