This from @renew_economy today is, I think, the most facile piece of 'analysis' of Australian energy I have ever read. https://reneweconomy.com.au/is-aemos-step-change-scenario-of-94-renewables-really-a-stretch-target-51027/

Almost comically published hot on the heels of renewables investment falling off a cliff, @renew_economy offers a little bubbling straight line of continuing growth.

Step Change scenario represents a world of "both consumer-led and technology-led transitions occur in the midst of *aggressive global decarbonisation* and strong infrastructure commitments".

It's the one-of-five scenarios that don't have 8.5 GW coal in 2041-42.

These scenarios 'will test the boundaries of system security and current operational experience'. It's going to need "multiple and well-co-ordinated efforts to progress DER,
VRE, firming capability, transmission development, system security, gas development and market
reform..."

And "they will need to start now, given the long lead times for major projects, the scale of reform required, and the imminent end-of-life retirement of significant volumes of coal-fired generation".

Yet out of this, @renew_economy starts intimating this is EASY?

Oh, there it is down the bottom - the reference to #nuclear.

Cause they screwed up, you see.

After years of saying "Nuclear will take 20 years and be really hard" AEMO is saying "this is going to take 20 years and be really hard and we will still have lots of coal at the end".

Oops. NOW how can they possibly justify their ideological stance? Because in a Step Change world of " technology-led
transitions occur in the midst of aggressive global decarbonisation", well, that's going to a world of swift and full embrace of all solutions, isn't it?

Parkinson says "step change” is not heroic from an installation perspective, as some people would make out – but it might be heroic from a transmission and integration perspective".

No kidding, Giles. And installation without transmission and integration of zero value.

The ISP is making it abundantly clear that even the Central scenario is a complex, multi-decadal challenge. Now is not the time to be telling Australia how simple it all is in the name of defending a pointless technology prejudice.
