This question, asked by Christian, at the Capacity Investment Scheme (CIS) webinar in August is excellent.

He basically asks which has priority:
- reliability
- prices
- supporting industry

The answers are extremely revealing. 1/ Image
It's directed to Salim Mazouz, General Manager of the CIS at the Dept of Climate Change, Energy etc... Basically the boss of the scheme.

Initially, he says reliability is the priority.

But he goes on... 2/ Image
And then claims something extraordinary.

He thinks that success in addressing reliability would push down prices, as a by-product.

Say.... what??

This is a disastrous misconception for someone in charge of the scheme to have... 3/ Image
... because it shows that the man in charge has failed to grasp the inevitable trade-off between reliability and damping price fluctuations. More of one means less of the other.

I outlined this in detail in my mega-thread on Saturday. 4/

But the pure gold comes from Salim's boss, Kirsty Gowans. Head of Electricity Division and DCCEEW (Federal Energy Dept).

She chimes in (her words) to tell us what the Minister, @Bowenchris, has on his mind.

And what follows is... well it explains everything. 5/
🥁🥁🥁🥁🥁🥁
@Bowenchris Chris Bowen is worried about consumer prices.

That's the "overriding issue" that the government is trying to manage.

Why?

"securing the broad community support for the energy transformation" which requires

"very significant investment" to be delivered. 6/ Image
@Bowenchris Kirsty goes on... She spells it all out.

The investment wouldn't be "politically achievable or sustainable" if passed onto consumers. So taxpayers stump up instead.

Boom.

How's that for an admission that the proposed renewable energy transition isn't going to be cheap. 7/7 Image

Time for a 🧵on the Capacity Investment Scheme (CIS), and this rather massive expansion.

Big expainer coming.

Let's start with what appears to be a proud announcement that something 'equivalent to half the current NEM' requires government Subsidies 1/
This is a picture-perfect snapshot of the naivety that will be our undoing.

32GW total 'capacity'.
Only 23GW generating (the rest just storing)
And that 23GW on average generating at 30% capacity.

It doesn't/won't power anything like half our grid. 2/

But to get back to the CIS and it's ambition, we need to understand it's primary objective... Ensure enough 'dispatchable' (ie controllable, you can turn it on when needed) capacity to retire coal.

And initially, it's all about storage. 3/ Image

This expansion of the 'Capacity Investment Mechanism' is enormous news.

I'll write a thread on it... later.

First, a thread on the probably-even-more-enormous news that will break, TOMORROW, that no-one will report on. 1/

theaustralian.com.au/nation/politic…
The critical event is this Energy Ministers meeting on Friday. I didn't know the exact date until reading this in the Australian article. The last meeting was in July, and the official communique just said they'll meet again in November. 2/ Image
Down the bottom of that Communique, the Energy and Climate Change Ministerial Council (ECMC) foreshadow some 'guidance' on the emissions reduction objective. It was due last month, haven't seen anything.
But this 'guidance' is massive. 3/ Image

On Friday @AEMO_Energy sent this email to everyone subscribed for ISP updates.

They announce the date for the draft release in the first sentence.

And the next three paragraphs sound insanely bureaucratic and boring... 🥱

With context, they're explosive. Don't miss this. 1/
Thanks to them sending this email, I've checked out some more of the details of the National Electricity Rules (NER).

In doing so, I think I've discovered a pretty clear-cut case of AEMO breaching the rules, around an event I outlined in this thread. 2/
Deep in that thread I point to the case almost 2 years ago when AEMO did exactly what Friday's email foreshadows, for the 2022 ISP Draft.

They issue an update to the previous ISP, essentially making the next draft the 'current ISP'. 3/

A couple of weeks ago, Queensland Energy Minister @MickdeBrenni cited this @EY_Australia report, to show "independent modelling" that demonstrates a rewewables grid was cheaper when questioned by @EnergyWrapAU.

This is a ripper. Buckle in. 1/
Image
Image
Let's start with the core problem, which Ben has nailed, and Mick can't respond to.

The whole thing is based on@AEMO_energy's ISP's 'Step Change', where all consumer generation/storage (DER) is provided at no cost to the system, and there's no change in distribution costs. 2/
Image
Image
Other models (NetZeroAustralia) recognise that distribution costs would nearly double.

It's utterly ridiculous for the ISP to claim they're optimising the 'whole system' while ignoring this.

As more people realise this, the ISP is aging like milk. 3/

Just had a NSW farmer track me down and give me a call. She had heard of my work on GenCost, wanted to see if I could help.

Eg, consider submitting something to the Central-West Orana project. Submissions close Wednesday.

Wait, what? submissions? 1/

energyco.nsw.gov.au/cwo#environmen…
See I'm just a city slicker... All I know about this energy transition is from what shows up in long pdf documents produced by CSIRO and AEMO.

And I'd heard of this Central-West Orana project.

It's 'committed and anticipated' in the 2022 ISP. 2/ Image
To be more specific... it's anticipated.

What does that mean? Three out of five criteria, from the ISP Methodology. 3/ Image

It’s been pointed out to me that a couple of weeks ago @CSIRO released this incredible ‘sorry, not-sorry’ explainer on GenCost.

A 🧵 on how their wanton conflation of private investor costs with system costs is now clear for all to see. 1/

csiro.au/en/news/All/Ar…
First-up… not sorry.

They’re repeating their claim. “Cheapest form of newly built electricity generation.”

Reading this, who would you guess it’s cheapest for? I’d guess end users. No other caveats present. 2/ Image
Then we get the admission they’re feeling some heat this year. I’ll take that as a compliment to my threads and video.

But they couch it as people misunderstanding ‘industry standard modelling’. Image
