As promised, there's a plot twist on this question about CIS funding curtailment.

The first 6GW of generation contracts of CIS did get funded for curtailment.

So @simonahac is dead wrong about this blanket claim.

But CIS is changing... maybe? 1/ Image
David Osmond has pointed this out, and I also know that Ben Beattie @EnergyWrapAU also discovered this.

The pro-forma contract for the upcoming round (closed, but not awarded, which is Round 4) removes the provision.

We're all in agreement there. 2/

The critical clause that's changed is 3.9.

The "Notional Quantity" which is the volume on which they get paid the agreed unit price included Force Majeure Events in the Round 1 tender, but that's been removed in the contract for Round 4. 3/ Image
Image
This change is only clear if you trace your way through all the equations and get confidence in them. As Ben and @DavidOsmond8 have done. But the contracts still explicitly include curtailment in the Force Majeure definition so it's confusing at a glance. 4/ Image
Just to give you an idea, if you pass the contract to ChatGPT4 it gives you exactly the wrong answer. It still thinks that the revenue would be underwritten. 5/ Image
If you ask it to step through the mathematical logic, it finds the right terms and definitions, but still comes up with the wrong answer.

This should be some kind of case study in the power and pitfalls of AI. 6/ Image
I had to really walk it through... point out the negative sign in front of the relevant term in the equation, for it to finally arrive at the right answer.

I don't think it's an exaggeration to say that the contract could be made clearer. 7/ Image
Image
So, the confusion is reflected in the Q&A responses that were published from the February application stages.

Someone asked the question on curtailment. In plain English.

And the answer from @DCCEEW was... "get legal advice".

What the....!??🤯🤯🤯🤯
8/ Image
That's the first reason why I'm even more pissed off with the SHaC excuse being used by @simonahac.

His mates will tell him something with confidence and clarity about the future rounds that the department won't even say to a proponent in the official Q&A!

What snakes! 🐍 9/
So Simon goes and embarrasses himself in front of the LinkedIn energy crowd... Crowing with confidence, discarding all evidence... on behalf of his cowardly buddies who wouldn't dare mumble the same claim in their official capacities.
Disgraceful. 10/
But there's another round of Q&A. The proponents have checked with lawyers. Who decoded the maths.

They asked to have the curtailment payment added back in again.

This settles, beyond any dispute, that the CIS did pay curtailment in the last round. 11/Image
But it's the answer here that is massively consequential.

Proponents may submit a "commercial departure" to change the deal.

And AEMO promises they'll frown upon this. They'll mark it down on their clipboard.
Rightio. 12/ Image
But here's the thing... That's completely non-binding. AEMO doesn't make the final decision. The Minister does. That's Chris Bowen.

They can say they don't want to change the documents, but at the end of the day, Bowen signs the cheques. 13/ Image
Image
So I think David Osmond's claim here is still wrong.

The CIS may well provide protection against curtailment. We will probably just never know about it. 14/

What I can't get my head around is the supreme arrogance and idiocy of the public service in this. If they don't want to fund curtailment, make it concrete. Make it clear. Rule out that modification.

Why mince words, with this "get legal advice" bullshit? 15/
Do they think that some proponents will have incompetent lawyers, and not notice? Insane.

Again... because he's still hiding, Simon's mate is a snake and a coward. How dare he give SHaC an official "cleared" statement to bandy it on LinkedIn, but obfuscate in officialdom. 16/ Image
These are the lucky 6GW CIS winners in Round 1.

Their curtailment is underwritten by taxpayers.

Barwon, Elaine, Mokoan... solar farms expecting 30-50% curtailment... underwritten!

Imagine how pissed you'd be if you were waiting for the next round, and missed out!
17/ Image
Image
Or I think, much more likely, they'll all submit variations. Or hike their bid in floor price to cover that risk. I just can't see how the CIS achieves the aim of supporting the investment without one of those happening. 18/
What explains this?
Only the desire to make it undiscoverable. Obscure the truth, so everyone can believe what they want to, including SHaC.
This is a positive disaster for transparency, and makes the CIS a petri-dish for corruption. 19/
The Minister has made @AEMO_Energy the administrator of the CIS, so that no Freedom Of Information claim can be made. And they never have to answer to Senate Estimates. The pro-forma can be modified. AEMO's assessment of merit will remain secret. And then... 20/
Chris Bowen will make the final decision.

That gives every wind and solar proponent both a strong argument, and powerful incentive, to persuade Chris Bowen himself to underwrite their project, like those before. 21/
And since AEMO's assesment of merit is just advice, and never discoverable, there's no reasonable way that Chris Bowen can be held to account for acting against it, and granting friends a favour, worth many millions, or billions of taxpayer dollars. 22/
This is absurd. I just can't see how that level of transparency is acceptable in a liberal democracy. I actually hope @simonahac agrees with me here.

I hope people of any/all stripes agree the CIS must change. 23/23

"No, you're wrong, because my friend in high public office assured me in private that I'm right."

This is the "SHaC excuse" for ignoring uncomfortable facts.

Last week @simonahac tried it on @EnergyWrapAU, who patiently and exquisitely dismantled Simon from public sources.
1/
The context is here... AEMO releases some modelling showing that vast proportions of the projected wind and solar being built will be 'constrained'.

I.e. wasted.

Unless utterly implausible amounts of transmission get built. 2/
afr.com/policy/energy-…
This is the critical figure from the @AEMO_Energy report underlying.

Unless we build out transmission on an impossible timetable, the curtailment will be massive.

Solar 🌞
SA > 50%
VIC > 35%
QLD > 20%

Wind 🌬️ more mixed, but on mainland more above 50% than below 5%.

On Friday I appeared on @SkyNewsAust, and commented Orica accepting a $430million subsidy for a 50MW green hydrogen project.

I've just started running some numbers... I think it looks far, far worse than I thought. 1/

skynews.com.au/opinion/slap-i…
The cost difference on consumeable inputs looks like at least $3/kg.

That's with expensive Australian natural gas, and an optimistic take on wholesale electricity, zero costs for network etc. 2/ Image
Winding in a capital component... If Orica plans on using the electrolysers at decent capacity to 20 years (ie they don't just stop when the subsidy runs out) that might add as little 80 cents per kg. 7% discount rate, which is standard for ISP estimates. 3/ Image

Every week @DavidOsmond8 does this copperplate simulation, demonstrating a net-zero grid is quite achievable and affordable.

Slowly, as energy literacy improves, I think he'll succeed in proving the opposite.

Let's chat through some charts. 1/
First, I admire Dave's persistence, and commend his transparency. He acknowledges the limitation of the copperplate assumption, that any energy from any source can be pooled, and consumed in any place is the biggest.

His defence "ISP's got this" will unravel slowly. 2/
But first, "perfect foresight".

Just think this through.

This week was BAAAD for wind and solar. The massive batteries got drained every night for the last four nights. They've never come close to max charge all week.

But this night, when the bottom out, what does the model do? Charge them immediately?

Nope. Leave them drained for most of the night, because the model knows the wind is going to rise. 3/Image

So VNI West has had its timetable shifted back a couple of years.

Apparently mostly because it's clear that they can't steamroll the farmers that fast.
1/

…files.s3.ap-southeast-2.amazonaws.com/1017/5124/5871…Image
This will be encouraging to the farmers like @MarciaMc10 who have been busy mapping out the community sentiment in the areas where these transmission lines must go. 2/
VNI West was only ever modelled as being useful around 2031, but was brought forward, essentially at the discretion of the Federal Government and AEMO. 3/

Spicy take: Transgrid's finances are shot.
They're no longer viable as a regulated utility.
Their shareholders are rushing for the exits.
Taxpayers are bailing them out.
Transmission costs will explode. Again.
This should be a scandal.
Quick 🧵 to explain. 1/
The key thing is Transgrid's credit rating. They're meant to be a monopoly utility, with access to low-cost capital.

As the CEO has explained: "If we blow our credit rating up, we can’t continue to invest in anything".

@angelamacd reported this. 2/

afr.com/companies/ener…
But the latest bonds Transgrid sold were at the very lowest 'investment grade'.

And the government bought them, $550mil worth through Clean Energy Finance Corporation, over the top of a lot of private investors.

@Johnkehoe23 noticed this. 2/

A couple of weeks ago I found this stunning chart.
Note the log scale.

That green line "Base Case" shows NSW being crippled by blackouts costing us between 10 and 100 BILLION dollars annually from 2029/30.
1/ Image
Also interesting... It appears that no matter what we do, we're heading for an increase in "involuntary load shedding costs" (ie economic destruction due to black-outs). Rising to between $100mil and $1bil in 2028-29.
Not great. 2/ Image
Not quite inevitable... There's Option 2 that has a gap in the line, because it leads to no blackouts at all in those years.

Phew. What a relief. 😅
Sure as heck we're taking Option 2!
