Renewable energy developers are pressing Opposition Leader Peter Dutton to reveal how much more wind and solar would be allowed to join the electricity grid under his plan to embrace nuclear reactors, amid intensifying doubts about what technology mix the Coalition is targeting.
Energy has become a key battleground issue ahead of the May 3 election, with voters set to decide between the Albanese government’s plan for renewables to make up 82 per cent of the grid by 2030 and the Coalition’s push to abandon that target in favour of building seven nuclear generators across the mainland by 2050.

Dutton says his plan for taxpayers to fund and own nuclear facilities would be cheaper than Labor’s strategy. To support this claim, he cites modelling from Frontier Economics comparing the total cost of the government’s renewables-dominated proposal against the Coalition’s competing vision for a grid powered 37 per cent by nuclear generation and 54 per cent by renewables.
But when quizzed about the impact of slowing the renewable rollout to ensure it did not exceed 54 per cent of the 2050 power mix, opposition energy spokesman Ted O’Brien insisted there was “no policy we have which is capping any technology”.
“A cap suggests you put a firm level and no more,” he said. “That’s never been our policy – it’s not our policy on gas, it’s not our policy on renewables, it’s not our policy on nuclear.”
The Coalition points out that the Frontier report had assessed the lowest-cost option to decarbonise the Australian electricity system, and did not suggest a cap must be implemented.
“Labor may be foolish enough to take an ideological approach to excluding technologies,” a Coalition campaign spokesman said. “But that has never been the Coalition’s plan.”
However, representatives for some of Australia’s largest renewable energy companies said O’Brien’s indication that the Coalition did not intend to stick to the technology mix outlined in its own modelling raised serious questions about its case for nuclear.
The Clean Energy Council, an industry group, has demanded urgent clarification on how much additional wind, solar and batteries the Coalition intended to allow beyond 54 per cent.
“There are enormous questions as far as their plans and targets for renewable energy are concerned,” Clean Energy Council chief executive Kane Thornton said.

The Coalition had stated its nuclear plan would significantly reduce the need for “industrial-scale” renewable energy and transmission lines in regional areas, Thornton said.
“Is that no longer the case? Have they changed their policy? And if so, what level of renewable energy deployment will they be targeting?” he asked.
Whether the 54 per cent ceiling on renewables in the Frontier modelling would constitute a “hard and fast cap” is a question that has come up in recent meetings between clean energy developers and the Coalition, according to industry sources, who requested anonymity to discuss private briefings.
The share of electricity generated from sun, wind and water is expanding each year in Australia, already comprising about 40 per cent of the power grid.
“If Peter Dutton is elected, he will find out that the [renewables] market is more mature than he might have anticipated,” one source said. “Even if it wanted to, the industry’s momentum will be difficult to slow.”
As Australia’s ageing coal-fired power plants near the end of their lives, Labor has followed the Australian Energy Market Operator’s advice about the best and lowest-cost path to transition away from coal. Those measures include accelerating the build-out of renewables, backed up by transmission lines, and fast-starting gas-fired turbines and storage assets such as batteries and pumped hydroelectric dams to stash clean energy for when it’s not sunny or windy.
The Coalition, however, argues that baseload power from coal and eventually emissions-free nuclear plants must be a crucial part of a “balanced energy mix” that would also include renewables, batteries and gas.
Against the urging of the energy industry, the Coalition is promoting a “coal-to-nuclear” transition, which relies on keeping polluting coal-fired power plants in the grid for potentially another 25 years until nuclear facilities are up and running.
The nation’s biggest coal plant operators, including AGL, say their ageing generators cannot continue operating that long without raising the risk of higher prices for consumers and more sudden outages.
Dutton often says his nuclear plan would lead to a 44 per cent reduction in people’s energy bills compared with what they would be under Labor. However, the Coalition’s policy costings make clear there has been no analysis of electricity price impacts.
The Frontier Economics report calculated that the Coalition’s plan for the electricity grid would be 44 per cent cheaper to build and operate than Labor’s – not that power prices would be 44 per cent cheaper.
The CSIRO and the energy market operator have cautioned that nuclear is an expensive power source, and have determined that Australia’s first nuclear plant would cost at least $16 billion and take years longer to build than the Coalition suggests.
