We've noted what seems to be an increasing tendency of all of us to reach for some form of "magic wand" as a cure-all for the vexed challenges confronting us in this energy transition.
Replacement of yet another blown LED at home on the weekend prompted me to dive into some historical voltage readings (made accessible through our Solar Analytics subscription). I present some results here, and hope...
Temperature forecasts are for hot weather in Queensland early this week - which means AEMO is forecasting high demand in the QLD region. With this, they are alerting on a forecast LOR2 Low Reserve...
Following from (what we have seen as) an increase in diversity of concerns (and claims) about different aspects of generator performance, we're leveraging our extensive data set and capabilities to have a deeper look,...
Based on a tip from a savvy WattClarity reader, we have a quick look at what turned out to be the lowest-ever (normal) instance of Scheduled Demand on a dispatch target basis in the...
Fifteen months after first speaking at Clean Energy Summit about the train wreck that's ongoing in terms of our mismanaged energy transition (and coincident with another industry gathering in the form of the AFR...
A detailed look at two specific trading periods in the day (Tuesday 24th July 2018) that saw negative dispatch prices occur at the start of trading periods - hence provided a case study for...
The multi-region islanding event on Saturday 25th August was a very rare event - perhaps the only one's that occurred in the history of the NEM. It has generated plenty of questions - and...

Both the QNI and the Heywood interconnectors tripped around the same time on Saturday 25th August 2018 (not apparent at this time which one was first, and why), leading to both QLD and SA...
A brief follow on from yesterday's post, with the advantage of being able to review yesterday's bids (and rebids) today.
The past week, with wind farm output blowing gangbusters in South Australia (coupled with low demand and System Strength requirements) we seen the "Wind Correlation Penalty" start to bite, with some reactions also beginning...
