Opposition leader Peter Dutton has outlined his plan to bring the renewable energy transition in Australia to a halt, keep coal fired power stations open, build more gas and use taxpayer funds to build nuclear power plants in the 2030s and 2040s – if the Coalition wins the next election.
Here is an explanation of the plan as far as we know it.
What are the details?
There are not many, because the nuclear “policy” has been released in a one page press release. The Coalition says it wants to build seven nuclear power plants – all at the site of current or former coal fired power stations – in five states. It favours a mix of small modular reactors and large-scale nuclear. It wants the first reactor built by 2035.
Where exactly will they be built?
Two sites in NSW (Liddell in the Hunter and Mt Piper near Lithgow), two in Queensland (at the Tarong and Callide power plants), one in Victoria (Loy Yang in the Latrobe Valley), one in South Australia (Port Augusta), and one in Western Australia (Collie).
Are the site owners OK with that?
No, they say they haven’t been consulted and they say they have their own multi-billion dollar plans to build clean energy and industrial hubs. AGL CEO Damien Nicks says: “There is no viable schedule for the regulation or development of nuclear energy in Australia, and the cost, build time and public opinion are all prohibitive. ” However, the Coalition says if the site owners do not co-operate they will compulsory acquire the land needed.
Which technology will the Coalition use?
It’s not clear. Dutton wants to build small nuclear reactors at two sites, in South Australia and W.A. But SMRs do not exist yet, none have planning approval, and none even have licences to be built anywhere in the western world. Of the two large scale nuclear technologies cited, one (APR1400) has not been ordered anywhere in the world outside South Korea for 15 years. The other, the AP1000, sent its maker Westinghouse bankrupt in 2017 and was the technology used in the Vogtle reactor in the US whose massive delays and cost overruns might make it the last ever built in that country.
When is the timeline for the Coalition nuclear build?
The Coalition wants the first SMR up and running by 2035, and the first large-scale nuclear plant by 2037, with the rest in the 2040s.
Is that realistic?
No. SMRs – for all intents and purposes – haven’t been invented yet. There is no design in any western country that has even been licensed, let alone been given approvals or started construction. Globally, the industry is hopeful of getting the first up by the end of the decade. Even Canada, with a well established nuclear industry and an available site, says it is unlikely to have the second SMR up and running by 2035.
The timelines for large-scale nuclear are even longer. All four projects built or under construction in the last three decades in the US, France, Finland and the UK have suffered massive delays and cost over-runs. Australia has no regulatory platform, and no existing industry, apart from the small reactor at Lucas Heights in Sydney. Even pro-nuclear advocates like former chief scientist Alan Finkel say nuclear cannot realistically be delivered in Australia until the 2040s.
What are the costs?
The Coalition hasn’t said anything about costs, which is not surprising. SMRs have not been built and the only one that got close was cancelled by its would-be customers because it would have been hideously expensive. The Coalition’s timeline of 2035 means it wants to be an early adopter. The CSIRO puts the costs at more than $600/MWh, which might be palatable for a technology used only rarely for evening peaks, but such a price for “always on” power would be insane.
Would it lead to lower bills?
All Australian and international studies show that the Coalition’s choice of technologies – nuclear, gas and carbon capture – are by far the most expensive. See CSIRO, AEMO, Lazard, and BloombergNEF. Energy analysts say the growing reliance on gas power while renewables are stopped and coal kept on line would lead to soaring prices and an extra $1,000 on annual bills for the average household. The nuclear rollout will be entirely funded and subsidised by the taxpayer, which means that – as in France, Ontario and elsewhere – the costs of nuclear would be borne by the government and hidden from consumer bills.
What would happen to emissions?
Emissions will rise significantly if the Coalition puts its plan into action. One study suggests it would result in some 2.3 billion tonnes of additional carbon emissions over the Australian Energy Market Operator’s step change scenario.
What about Australia’s obligations to the Paris climate treaty?
The Coalition has made clear it will not seek to meet the current interim target of a 43 per cent cut in emissions. That means it is effectively ignoring the climate treaty, which requires no back-tracking on committed targets.
What about the net zero by 2050 target?
The Coalition says it still intends to meet that – but, by stopping wind and solar and building more gas, that target looks impossible under their plan.
The Coalition says the sites were chosen because they will not need new transmission. Is that true?
No. The site owners have their own plans. In Port Augusta, for instance, the grid capacity has already been mostly taken up by new wind, solar and batteries. “The myth that a nuclear reactor could just plug into the old Pt Augusta coal power station transmission lines is not true,” says South Australia energy minister Tom Koutsanstonis. “The transmission lines are already nearly full from new renewables. In truth, a nuclear reactor at Pt Augusta would need new transmission lines, the exact thing the LNP are complaining about.” And the large-scale nuclear reactors cited by Dutton will be twice the size of any existing unit in Australia, so it will need more grid infrastructure, and also more “back-up” in case those units fail.
The Coalition says the market operator has warned that the reliance on wind and solar will mean the lights will go out. Is that true?
No. The Australian Energy Market Operator says the biggest threat to energy reliability and security is the failure of ageing and increasingly unreliable coal fired generators.
The Coalition says wind and solar cannot power modern economies and businesses. Is that true?
No. The owners of Australia’s biggest smelters and refineries, including Rio Tinto and Ark Energy, are contracting multiple gigawatts of wind and solar to power their assets. South Australia says it has been flooded with inquiries from business with more than 2 GW of energy demand seeking to move to the state to access cheap wind and solar.
The Coalition says wind and solar cannot provide more than 10 per cent of the energy mix without causing problems. Is that true?
No. South Australia already enjoys a 75 per cent share of wind and solar, and the isolated W.A. grid has had 36 per cent wind and solar over the past year. The market operator says instantaneous levels of 100 per cent should be achieved in coming years.
The Coalition says the Labor government wants to build 28,000 km of new transmission lines by 2030. Is that true?
No. The market operator’s system plan envisages just over 5,000 km by 2030, one third of which have already been built, and some of the rest needed by growth in population and industry. The 28,000 km number comes from the “green export superpower” scenario and is for 2050. That assumes a switch from fossil fuel exports to green industries (steel, power, ammonia), and would likely be required whatever the technology.
Isn’t nuclear banned in Australia?
Yes, at federal and state levels. If the Coalition wants to repeal the laws it will need to get it through both houses of parliament, and who knows where the numbers will be after the next election, with the two-party preferred polls even stevens and any number of independents and minor parties also likely to emerge.
Do the states want nuclear?
No. The Labor governments in Queensland, NSW and Victoria have state laws against nuclear and intend to keep them. LNP Opposition leader David Crusafulli, favoured to take power in Queensland’s election in October, is also against nuclear. State governments in Western Australia, South Australia and even the Liberals in Tasmania are also opposed to nuclear, but legal experts say if the Commonwealth pulls rank, it is heading for the courts.
What if local communities object?
Nationals leader David Littleproud has spent the last few years defending the right of communities to oppose wind, solar, battery and transmission projects, and has demanded a pause and a “re-set.” But he says the Coalition will brook no opposition to its nuclear plans. If local communities don’t like it, tough luck. “We need strong leadership in this country, to have the courage of its convictions, to follow through and to make the tough calls in the national interest,” he told the ABC.
What will be the future of large-scale renewables under a Coalition government?
If the Coalition wins power, it won’t be good. Littleproud wants them stopped, and has vowed to rip up contracts written by the Commonwealth under the Capacity Investment Scheme, which could have 12 GW of capacity lined up over the next 12 months. States may plough on, but will face roadblocks and vetoes on projects. Investors say they need certainty.
So what is the real strategy here?
It’s pretty clear that the strategy is less about building nuclear and more about stopping renewables and protecting the fossil fuel industry, something that the Coalition has not been shy about for the last two decades. It will lead to higher costs, more emissions, squandered industry opportunities, and make the grid less reliable.
Will the strategy work?
Quite possibly. To people in the industry, pushing nuclear and walking away from Australia’s low cost wind and solar resources is nuts – from an engineering, economic and environmental point of view. But 95 per cent of people do not know, and are not interested in, the fine details of the complex energy system. They just want cheap power and the lights to stay on.
And to many of them the Coalition’s fear mongering may sound entirely plausible, particularly when the obvious misinformation is not contradicted by mainstream media – with a few notable exceptions such as The Guardian. See Trump, see Aboriginal voice referendum.
The fossil fuel industry is funding a massive campaign on social media to share simple and effective stories that make nuclear sound sensible and wind and solar as madness. They didn’t just think of this yesterday. If the renewable energy industry and Labor are not careful, they will lose this battle for hearts and minds.
Wow, that was exhausting. Do you need a lie down?
Yes.
