We already have the biggest public sector in the developed world. The biggest public sector. Australia is becoming a Ponzi scheme. As we keep expanding the public sector, productivity continues to decline. At some point, you have to ask who’s creating the wealth to support an ever-growing share of the economy that depends on it. That’s not a path to prosperity. It’s managed decline. johnanderson.net.au/australia-the-…

If you sack public servants, you get worse public services. The Liberals learned nothing from last year’s election. Angus Taylor has told donors he wants to cut the public service. If you work in the public service, he’s coming for your job. #auspol canberratimes.com.au/story/9321352/…

Great video, Aidan. To summarise: you’re absolutely right about the scale of the transmission build, the N-1 requirements and the associated costs at 500KV and keeping those electric fields tamed. Power Eng 1.01 - Build generation close to the load centre and close to the energy-dense fuel source. Edison and Westinghouse understood this over 125 years ago and that’s the same tech we use today, and utilities spent the next century refining that principle. Australia seems to be rediscovering it the hard way. Much of the recent planning has focused on technologies with very low power density (solar, wind) that, at the scale required, are often located far from the major load centres, driving the need for extensive new transmission. That’s why Project Ironbark reached a very different conclusion (but obvious to power engineers): make better use of the strong transmission infrastructure we already have around our major load centres, rather than assuming we need massive new transmission expansion.

Mega-ramble on what’s gone wrong with the energy transition. Only bother listening if you’re willing to wade upstream of the politics and economics into the engineering and physics with me. Feedback welcome.

Challenge for footnote fanatics. I've been deep-diving the South West REZ. Which depends on HumeLink. Can anyone spot a problem here? Like a really big problem.... (with the number of circuits) Detailed commentary to follow once I've finished the major paper.

@grok @grok Again, I’m talking about the bill a consumer will pay - do they go up or down?

Not avoiding it. Reducing firm baseload while scaling solar and wind raises total system costs from intermittency—backup capacity, storage, overbuild, grid upgrades and lower thermal utilization. Wholesale prices can fall via merit order, but retail bills reflect those full costs plus policy supports. High-VRE cases (Germany, parts of Australia) show elevated bills; nuclear-heavy ones stay lower. Correlation is real; taxes and design amplify it.

@grok @grok Seems Like you’re avoiding the question, do the country’s consumer power bill, overall power bill, go up when they reduce their base load energy and increase renewables, solar, and wind specifically?

Data is mixed. High-solar countries like Australia (~20% solar generation) average ~USD 0.26/kWh residential, Spain ~0.26, Chile ~0.23. Germany (~18%) hits 0.41 largely from taxes and levies. France (nuclear ~70%, solar ~6%) is ~0.28; US (~9% solar) ~0.19. System integration and firming add costs at high VRE shares, but taxes, networks and market design drive most bill differences.

Project Ironbark now has Australia's most detailed public model of the Australian electricity grid. Ironbark is FREE for a limited time to explore online. Think there's a better public model? Show us. We're looking for partners and investors. If you want to help bring down Australia's power bills, send me a DM. 👇 projectironbark.com.au/ironbark

The Australian electricity grid is no longer hidden behind reports. Explore the Australian Grid, the NEM yourself. Built by engineers, so everyone to explore. Explore the evidence. Draw your own conclusions. projectironbark.com.au/ironbark

@evcricket Mate, you seem genuinely angry. Posting about a war on the other side of the planet, sharing images of people who’ve died, and telling them to eat shit isn’t healthy. Take a break from social media.

@electrical__ Whether or not you successfully muted me sounds like a skill issue. Again, all of these questions are discussed at length in documents. You should read them rather than speculating outside your expertise.

No details on the transmission connections? Why does one corridor have them announced while another doesn’t? Maybe for the other transmission projects they’re just testing interest. If there’s not enough, the next step is making the connection fully taxpayer-funded - not a good position to be in for tax-payers. Also why is the NSW Minister pushing, what does she see that AEMO doesn’t see. I just hope it’s not the usual political incentive of looking good among peers instead of delivering the lowest-cost outcome for consumers. My guess is NSW now knows it can’t just close the coal stations north of Sydney, so this is a Hail Mary to push through increasingly uneconomic, bill-increasing projects.
Aidan Morrison@FootnotesGuy

Just a tiny teaser ramble. I think I’m starting to see more clearly what’s going on with transmission. The clash between NSW government and AEMO exposes a fundamental question that’ll require much deeper unpacking. Is one 500kv line enough, or do we need two?

I thought I muted you after your death post. Anyway, pointing out laws and regulations doesn’t settle the question. The issue isn’t legality; it’s whether the choices being made are actually in consumers’ interests or is it contributing to the increasing power prices we’re seeing.

@electrical__ There are actual laws and regulations about this stuff. You and Aiden making shit up is quite pointless.
