Lot's of RE curtailment in the NEM - just ticked over 6TWh for the last 12 months

Not every electron is sacred - but there's plenty of room for improvement!

Union of Concerned Scientists report out with some nice recommendations for how to avoid captive residential customers paying for the infrastructure needs of data centers owned by tech giants (which is currently happening):
Customers in 7 PJM states paid $4.4B for data center transmission in 2024: report
Transmission lines built for data centers fall into a "regulatory gap,” with utility customers on the hook for the costs, the Union of Concerned Scientists said.

$16 billion. That's how much the PJM market monitor estimates that electricity ratepayers will pay via increased utility bills to subsidize interconnection of data centers owned by Big Tech. A massive give-away to some of the most profitable companies in the world.

"At its peak, Musk had around 35 natural-gas turbines at the site, capable of producing 420 megawatts of power, enough to power the roughly 250,000 homes in the Memphis city limits"

35 (!) full-sized power plants for this one data center run by the world's worst poster.

You can have a situation with rising renewable absolute output and percentages of total (and falling emissions intensity!), but also stagnant or even rising greenhouse gas emissions: when *demand* itself is rising fast.

This is very clearly the case in Aus, and it should trigger alarm bells

.. are you looking at Q3 to Q3 numbers?

Black coal numbers are up Q3 to Q3 (for both 2023 to 2024, and 2024 to 2025) - including on open electricity

De Brouwer made the exact same argument two years ago after the Robodebt Royal Commission report was delivered. This is how I treated it in Mean Streak: "Grow up."
Screenshot of the book Mean Streak by Rick Morton. The text reads:

for the past decade and half, when conclusive certificates were
discontinued, is counterproductive to the Parliament’s intent.
‘When it comes to deliberative material, FoI does not ensure
transparency (because advice is not being written) and it
undermines integrity (because advice is not being written).’
So officials don’t put things in writing because they might get
released under Freedom of Information laws, therefore the FoI
laws aren’t working?
Grow up.
De Brouwer is not alone in his views. Former secretaries have
been doing the rounds making exactly these kinds of noises, as if
the outcome of poor professional behaviour is the result of some
law and not … poor professional behaviour.

Some regional variation - for example in NSW, growth in underlying demand was greater than growth in RE

#BREAKING 🚨 Deloitte to refund government, admits using AI in $440k report into mutual obligations issues.

Fake quotes from Federal Court case that ended Robodebt deleted from new report in Friday DEWR dump.

HEADLINE: Deloitte to refund government, admits AI errors in $440k report Deloitte Australia will issue a partial refund to the federal government after admitting that artificial intelligence had been used in the creation of a $440,000 report littered with errors including three nonexistent academic references and a made-up quote from a Federal Court judgement.

A new version of the report for the Department of Workplace Relations (DEWR) was quietly uploaded to the department’s website on Friday, ahead of a long weekend across much of Australia. It features more than a dozen deletions of nonexistent references and footnotes, a rewritten reference list, and corrections to multiple typographic errors.

(photo of Deloitte Australia HQ) Deloitte Australia has made almost $25 million worth of deals with the Department of Workplace Relations since 2021. Photographer Dion Georgopoulos The first version of the report, about the IT system used to automate penalties in the welfare system such as pauses on the dole, was published in July. Less than a month later, Deloitte was forced to investigate the report after University of Sydney academic Dr Christopher Rudge highlighted multiple errors in the document.

At the time, Rudge speculated that the errors may have been caused by what is known as “hallucinations” by generative AI. This is where the technology responds to user queries by inventing references and quotes. Deloitte declined to comment.

The incident is embarrassing for Deloitte as it earns a growing part of its $US70.5 billion ($107 billion) in annual global revenue by providing advice and training clients and executives about AI. The firm also boasts about its widespread use of the technology within its global operations, while emphasising the need to always have humans review any output of AI. SUBHEADING: Deleted references, footnotes

The revised report has deleted a dozen references to two nonexistent reports by Professor Lisa Burton Crawford, a law professor at the University of Sydney, that were included in the first version. Two references to a nonexistent report by Professor Björn Regnell, of Lund University in Sweden, were also deleted in the new report.

Also deleted was a made up reference to a court decision in a leading robo-debt case, Deanna Amato v Commonwealth.

The new report has also deleted a reference to “Justice Davis” (a misspelling of Justice Jennifer Davies) and the made-up quote from the nonexistent paragraphs 25 and 26 in the judgement: “The burden rests on the decision-maker to be satisfied on the evidence that the debt is owed. A person’s statutory entitlements cannot lawfully be reduced based on an assumption unsupported by evidence.”

* They are still burning some coal when they are doing this - be interesting to know how much exactly.

This is what whole power station was doing: "Peaking coal" .. ~1600MW increase in space of a couple of a couple of hours.

This is pretty amazing from Bayswater Unit 2 over the weekend - so-called "two shifting".

i.e. black coal turning off* in the middle of the day due an abundance of RE and low prices.

"AT Proto decentralization doesn't exist as a practical reality, and if it ever does it won't be for years"

This is a great post and it is a huge, huge shame to see @jay.bsky.team switching into Musk-Mode. Absolutely irresponsible and really gross.

Fair - (but would also point out that previous ESoO's also said that Eraring closure would be fine if x and y happened).

(also in the NSW case, electricity price concerns were also a factor, separately from reliability - an argument which may or may not feature in this case as well).

Yeah I reckon you're right .. but also this update from AEMO might scare the horses

(.. the new 'QLD Roadmap' is due next week, which might have something to say too)
