Returning to the theme of analysis of Q2 prices (completed in 2017 and 2016 due to Q2 historically being an uneventful period) we see that prices have backed off from the “off the charts” level of 2017, but are still much higher in all regions than most other regions. In some cases results are second worst in 20 years.

Some further thoughts on what we’ve termed a “Solar Correlation Penalty” which point-view of some specific dispatch intervals seems to suggest is occurring
All too often people (including us sometimes, unfortunately) are quick to attribute some particular outcome to a single contributing factor. Almost always this is an over-simplification.
Highlighting the temptation to ascribe motivation to others – despite the fact that we understand that we can never know for sure.
The start of some analysis that helps to identify the variety of factors that combined to give a shaky balance between supply and demand in NSW last week.
A comment made by TransGrid at the Energy Networks 2018 conference today jolted me to update my (somewhat) outdated paradigm of declining demand.

Yesterday (Thu 24th May) AEMO issued a Low Reserve Condition notice (at LOR2 level) for South Australia next Thursday 31st May. We take a quick look….
This morning over on Twitter, I was pulled into a discussion that had started with respect to volume of wind energy curtailed in South Australia: The genesis of this…
A brief first look at AEMO’s new MT PASA data sets – as we push forward in the next upgrade of our ez2view software to help our clients understand the data, and the opportunities (and threats) that the data reveals.
Already we are seeing the highly correlated output of solar PV deliver interesting challenges for the NEM – both to the project proponents themselves, and also to the “everything else” that supplies what’s left of the underlying demand from electricity from any source.
Alerted by our NEMwatch dashboard, I delve into the data and see a scary degree of correlation between the (very low) output of wind farms in south-east South Australia, and (similarly low) output from newer wind farms in northern NSW.
An unexpected network outage in the south-east of South Australia restricts supplies from Victoria at a time of low wind supply in South Australia and results in the dispatch price spiking to $14,200/MWh from 11:30 and oscillating for the afternoon
Following from a steady stream of questions we receive in relation to a range of our products (but in particular with respect to “the RenewEconomy Widget”) we’ve invested some time to put this post together to explain some of what we understand about electricity demand.
An advertisement seen on TV in recent days from a (relatively) new entrant in the energy sector reinforces, to me, the need for the energy sector more broadly to do a much better job of respecting its prospective customers.

Queensland experienced a new record for Scheduled Demand for electricity today – but what’s particular staggering is how late in the day it happened!
A brief look at the numbers with the temporary coal supply issue affecting Loy Yang A and Loy Yang B overnight
Looks like being an interesting day on Wednesday next week (14th February 2018) with high temperatures currently forecast for parts of both QLD and NSW
On a day when high temperatures drove demand in Victoria above 9,000MW (and NEM-wide demand above 30,000MW) we saw some price volatility – with prices in VIC and SA up around $14,000/MWh
