Peter Dutton’s declare that nuclear power would result in cheaper energy payments has been rejected by power specialists, with one saying there was “no credible reason” to suppose including “the most expensive form of bulk electricity” would lower costs.
They mentioned a variety of proof, together with a latest CSIRO evaluation, advised nuclear energy can be costlier than different choices, and that photo voltaic and wind system below building – supported by firming expertise – was the most cost effective choice.
The opposition chief on Wednesday revealed the positioning of seven proposed nuclear energy crops that he mentioned can be constructed and owned by the commonwealth below the Coalition.
Dutton didn’t present proof of how a lot the crops would price, clarify how the Coalition would carry legislated federal and state bans on nuclear energy, or say why the Coalition believed the primary two crops may very well be on-line by 2035 or 2037 – a a lot quicker timeframe than specialists say can be doable.
He mentioned nuclear power would result in “cheaper, cleaner and consistent electricity” than Australians had below the Albanese authorities, and its dedication for 82% of technology to come back from renewable sources by 2030.
Dr Dylan McConnell, an power methods researcher on the College of New South Wales, mentioned there was “no credible reason to think that adding the most expensive bulk form of electricity would make electricity prices go down”.
With a majority of the nation’s coal-fired energy crops attributable to shut over the subsequent decade, Dutton mentioned that the Coalition would use much less renewable power and as an alternative assist new gas-fired energy, a fossil gas, to make sure the electrical energy grid remained dependable till nuclear crops had been on-line.
However McConnell mentioned fuel energy was additionally a considerably costlier type of electrical energy within the nationwide grid than photo voltaic and wind, and utilizing extra of it than wanted would push up costs. “Gas is not cheap. It’s a huge cost,” he mentioned.
The Grattan Institute’s power and local weather change program director, Tony Wooden, mentioned the Coalition had not backed up its declare that nuclear technology can be a less expensive choice. “There’s nothing in what we’ve seen so far that would substantiate the claims that it’s going to be a certain price at a certain time,” he mentioned.
Wooden rejected the Coalition’s declare that electrical energy was costly right this moment attributable to Labor’s renewable power insurance policies. “It’s not true,” he mentioned.
He mentioned electrical energy costs leapt 20% final yr attributable to Russia’s assault on Ukraine pushing up fossil gas costs, a scarcity of obtainable fuel, previous coal crops having unscheduled outages and excessive climate resulting in some coalmines being flooded. He mentioned that they had since began to come back again down.
Wooden mentioned the Coalition’s local weather coverage would most likely result in it having to pay coal-fired energy crops to remain open longer than deliberate, a step already being taken by the New South Wales and Victorian governments, and that counting on fuel energy can be “more likely to lead to more expensive electricity”.

McConnell mentioned claims by the Coalition that nuclear energy had led to decrease costs in different jurisdictions – together with Canada and France – had been deceptive, and irrelevant to the prices that will be confronted in Australia. He mentioned each had established nuclear industries many years in the past, however the price of wholesale electrical energy from nuclear technology in Ontario was nonetheless larger than the wholesale price in some Australian states from new, firmed renewable power.
McConnell mentioned it was “extremely dubious” that nuclear crops may very well be inbuilt Australia earlier than 2040, because the Coalition claimed. “Nuclear is just not able to address the things we need to do in the electricity sector in the timeframes they need to be addressed,” he mentioned.
Wooden mentioned this significantly utilized to the Coalition’s plan to probably use small modular nuclear reactors, a expertise that isn’t but confirmed commercially viable, in South Australia and Western Australia by 2035. “The timeframe there seems remarkable,” he mentioned.
The Coalition needs to construct the crops on the positioning of current or previous coal-fired crops at Tarong and Callide in Queensland, Mount Piper and Liddell in New South Wales, Collie in Western Australia, Loy Yang in Victoria, and close to Port Augusta in South Australia.
The advocacy group Options for Local weather Australia mentioned the Coalition’s nuclear proposal was a “fantasy”. The group’s director, Dr Barry Traill, mentioned its evaluation discovered the Coalition’s method would result in at the least 2.3bn tonnes of heat-trapping carbon dioxide being pumped into the ambiance because the nation used extra fossil fuels and fewer renewable power within the many years forward.
“We can’t afford to wait,” he mentioned. “Action this decade is critical.”
