We need someone like him in Australia

SA's Network looks schizophrenic, and drags down the entire system.

@roobar1984 @happydays00769 @AEMO_Energy the ISP2026 is a plan for net zero only, and it excluding nuclear.

The ISP is not a plan for the cheapest and most reliable NEM. AEMO make this clear.

[Jon Carroll (Aus) @electrical__]

Yup, Canada & USA are surging liquid fuels and thermal generation yet @AEMO_Energy is playing net-zero checkers while the rest of the world is building a civilization

[Nuclear for Australia @nuclearforaus]

Canada is expanding nuclear energy to meet their energy and climate goals.

Despite rising electricity demand, Australia is the only G20 member with a ban on nuclear power.

Read the GHD report referenced in the ISP on O&M costs for the existing generation fleet. Then compare it with the annual reports from AGL and Origin, they show broadly similar operating and sustaining capital costs.

That is the starting point: maintaining and refurbishing the existing system. In other words, the business-as-usual baseline.

The ISP itself is clear that it does not model a true business-as-usual scenario. The comparison is therefore not against simply maintaining the existing fleet, but against alternative transition pathways.

One day Minister Chris Bowen writes to the ACCC complaining about rising network costs. The next, he's backing his policies that require vastly more network investment.

@AEMO : why not model a baseline that builds generation close to load centres, use existing transmission and fuel infrastructure, minimising new "security infrastructure"? This way the people can see the true cost.

That's Power Engineering 101.

[AEMO @AEMO_Energy]

Today, AEMO has published the 2026 Integrated System Plan (ISP), the least-cost roadmap for the NEM, bringing together generation, storage & networks to support reliable electricity as consumption nearly doubles, while meeting government policy.

[Jon Carroll (Aus) @electrical__]

@roobar1984 @aemo Business as usual is in the order of 4x cheaper. And because of the hubris of the PM recently, It’s likely getting repealed sooner.

[Jon Carroll (Aus) @electrical__]

If they weren't constrained by "government policy", @AEMO_Energy would likely plan new and refurbished generation close to load centres and existing fuel infrastructure—which, of course, is largely how system is configured today 😁

@AEMO_Energy ISP 2026 renewable lull stress test.

The event is driven by low wind, yet solar appears relatively strong on almost every day, with only one noticeably low solar day.

What happens if there were two or three consecutive low-solar days during the same wind lull @AEMO_Energy?

[Jon Carroll (Aus) @electrical__]

If Labor is willing to let Tomago Smelter close, it becomes much easier to shut Eraring earlier - seems to fit what Labor wants.

Tomago is one of the NEM’s largest electricity loads. Without that demand, less generation is needed and congestion on key transmission corridors, including the Bannaby–Canberra and Sydney South corridors, is reduced.

Everything in the grid is connected.

Surprise Power Bill Rise? Hardly a Surprise.

Minister Bowen is either naive or being disingenuous if he claims not to understand why electricity prices are rising. Network costs are set to increase significantly, particularly if projects such as Snowy 2.0 and the extensive transmission infrastructure required for the Renewable Energy Zones (REZs) proceed as planned.

Australians are being told cheaper power is just around the corner, yet the cost of building and financing this infrastructure will ultimately be reflected in consumers' power bills.

@EnergyWrapAU Ohh! How is she the head of the AEMC? There are so many alarm bells in that 52-second clip alone.

[Dr Aseem Malhotra @DrAseemMalhotra]

Great to be interviewed by Australia’s most well known news anchor @karlstefanovic for his podcast. We covered THE root cause of health crisis and my recent testimony in US Senate. ZERO censorship here 👊🔥

[Jon Carroll (Aus) @electrical__]

@EnergyWrapAU Yup I always hear the averages argument, like “there’s usually plenty of solar generation on hot days.” But network/power engineering is about the opposite — modelling the rare one-day-in-a-year events that drive reliability requirements.

[Jon Carroll (Aus) @electrical__]

From memory, he meant the tunneling. But I guarantee, just like me, he has no idea about the complexities and unknowns with tunneling.

To understand the tunneling, you’d need to see the Geotech report and all the test drilling, that’s the thing with these big projects they get announced before the huge amount of geotechnical engineering is done.

[Jon Carroll (Aus) @electrical__]

@FootnotesGuy Paul Broad said the hard part was done, I guess I shouldn’t be too shocked that it’s not.

I still think they will try to find a way to have it ‘future ready’ - basically have a plausible off-ramp for people who have sunk their professional reputations on the project.

[Jon Carroll (Aus) @electrical__]

@FootnotesGuy @PaulineHansonOz Can it

[Jon Carroll (Aus) @electrical__]

@FootnotesGuy Yup, true. I remember reading about this in Simply Electrifying years ago. Its a must read.

looking to the past is a great way to see what's going wrong now, and what funding models worked in the past.

[Jon Carroll (Aus) @electrical__]

@FootnotesGuy @PaulineHansonOz Ha! Is it a full cancel or finish the tunnel and downsize the output? Look just saying I might have a plan😉

[Jon Carroll (Aus) @electrical__]

@grantbuttenshaw @FootnotesGuy Be cautious with V2G, will make resale of your EV harder.

E.G. Very hard to replace a car battery, very easy to replace a house battery. Your EV may be useless in 5 years with all the cycles.
