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….Read More
Autumn 2018 in the NEM
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 twitter conversation was the AEMO’s “Quarterly Energy Dynamics – Q1…
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
A follow-on to my earlier article of a couple weeks ago, looking at another instance where a team effort was required to counter a drop in system frequency following the loss of generation at a large power station (this time the single unit Kogan Creek power station – the largest single unit in the NEM).
