Analysis released by the federal government has shown that the Coalition’s proposal to cap large-scale renewable energy and eventually build nuclear power plants would lead to “massive” electricity supply shortages risking blackouts.
The climate change and energy minister, Chris Bowen, released the findings of an energy department analysis that suggested electricity supply could be at least 18% less than what will be needed in 2035 under a scenario that reflects the few details of the Coalition plan that have been released.
Those details include the country building fewer solar and wind farms, the cancellation of the “rewiring the nation” policy to build transmission lines, extending the life of ageing coal plants and building nuclear plants at seven sites.
Under a scenario in which about 90% of remaining coal generation closes by 2035 – consistent with what the Australian Energy Market Operator (Aemo) projects – the gap between demand and supply could be 49%, according to the analysis.
Bowen said it showed Peter Dutton would “take to our finely tuned electricity system planning with a sledgehammer” and cause “massive supply shortages over the next decade”.

“The question that Mr Dutton has to answer is: where would the electricity come from if we stop building renewables now and nuclear takes so long?” Bowen said at a media conference. “He wanders around making outrageous accusations about blackouts under this government when in fact it’s his own scheme [that] is the biggest risk to reliability in Australia.”
The analysis, released via an opinion piece in The Australian, is timed to precede a speech by Dutton on Monday on whether nuclear power could work in Australia.
Dutton and the opposition treasury spokesman, Angus Taylor, rejected Bowen’s analysis in TV interviews on Friday, but declined to release details of their proposal. Speaking on Sky News Australia, Taylor said Bowen was “full of nonsense” and Labor’s policies would “always cost Australians more than our alternative policies”.
The Coalition has said if elected it would use public money to build nuclear plants at seven sites. It has suggested it would also cap investment in large-scale renewable energy and back more gas, a fossil fuel responsible for 21% of Australia’s climate pollution.
