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/
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.
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/
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/
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/
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/
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/
