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/
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/
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/
... 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/
New paper out yesterday from Paul Simshauser and Joel Gilmore.
Serious study.
It represents (another) death-knell for the hallowed AEMO Integrated System Plan, and any such weather-dependent plans.
Peaking gas isn't the easy backstop for bad weather we thought. 1/
Why another death-knell for the ISP? Well because for a full year, the Government has sat on their own review of the ISP that identified this as a serious problem.
The ISP has (again) assumed enabling infrastructure exists that might not be economically viable. 2/
Here's @AEMO_Energy officials, including CEO, telling a recent Senate committee how important gas firming will be.
Not long ago, they downplayed that fact too.
But they've known all year what this report confirms: it won't work.
Time to take a look at @DavidOsmond8's latest defence of the weather-diversity argument.
Dave's own model is a copperplate one, no transmission limits.
So it's important to see how he arrives at the conclusion that it'll all be ok, the ISP's got this. 1/
First, just 2-3GW of wind flowing from Qld to NSW... Well, let's assume that's enough for a moment.
Contrary to Dave's claim, the ISP does not cost this.
The ISP only includes QNI Option 2.
The Transmission Expansion Options report makes it clear that this provides less than 2GW capacity.
Still costs 2.5 billion mind you.
And this is for about 100km longer line than HumeLink, which is 2.2GW for 360km, and costs 4.6bn.
Still a loose estimate, it'll go up.

That’s my problem with your work Rosie. You refer to the ISP without thinking about it. Please think more about it before you reference it for projecting what is happening or will happen! 🙏
Eg any wind being developed now will be in the ISP, but NOT COSTED, because “committed”
And please don’t take that personally… I think more about more people failing to think about the ISP before they talk about it than anyone else I know.
You have plenty of company… including essentially every current and recent energy minister.
And yes, I think a lot of blame belongs at the feet of @AEMO_Energy and @dfwesterman for persistently making it difficult to discern what the ISP actually is and is not.
Unthinking references to the ISP are almost always false and misleading as a result.
The punchline is here: The BIS Oxford Economics analysis paper, commissioned by AEMO to inform the scenarios for the 2023 Inputs, Aussumptions, Scenarios Report.
The Progressive Change scenario, that the Coalition prefers has MORE Aussie industry, driven by mining. 2/
No, that's not a typo. The original narrative for Progressive Change did include economic challenges, but certainly not a collapse in Australian industry.
BIS Oxford thought industry would surge with demand for our fossil fuels. 3/
