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 from guest author, Connor James, about “what’s next” in response to energy user concerns about high and escalating prices.
Following Wednesday’s article by Paul McArdle on WattClarity, we’ve reviewed the (very cloudy) weather patterns for Friday 19th May 2017, and the accuracy of Solcast’s predictions of a day of low solar PV output
Some thoughts about challenges with intermittent solar PV, triggered by this week’s Solar Eclipse in North America
A few thoughts about how energy users (including each of us) are the main victims in the unfolding train wreck that’s become of this energy transition off the rails.
AEMO data for the National Electricity Market shows business consumption of electricity is more than twice that of residential consumption of electricity
A quick note about high wind speeds in South Australia this afternoon leading to AEMO constraining wind farm output down for System Strength reasons.
Low energy prices in South Australia combined with high prices for Raise Regulation
A timely reminder from Rod Sims (at the ACCC) this week that there are a number of factors driving electricity price higher – not just a single “smoking gun”
An energy crisis (like a train wreck) is upon us.
A collection of articles about this energy transition
Articles pertaining to summer 2017-18 in the NEM
Articles pertaining to spring 2017 (Sept, Oct, Nov) in the NEM
This is a category of articles that have been accumulating on WattClarity for some time, aimed at helping to tame Villain #4, which is what we see as a growing deficit in Energy Literacy/Numeracy required to effectively deal with the…
Our guest author, Allan O’Neil, posts an overview of the strengths and weaknesses of an increasingly popular metric – the LCOE (or Levellised Cost of Energy)
A quick outline of what have been (in my view) the three key reasons why wholesale electricity prices in Queensland have risen, compared to 5 years ago.
An explanation of how the Southern Annular Mode (SAM) contributed to the wind drought we observed recently on WattClarity.
A year on from my review of “remarkable” prices seen in Q2 2016, I return to the same analysis and update for Q2 2017. Outcomes are even more extreme…
