Key question Peter Dutton refuses to answer about his nuclear power plan

Peter Dutton refused to answer questionHe was probed about nuclear power policy

Peter Dutton has again refused to reveal key details on the Coalition's nuclear power policy, declaring he would consider announcing his alternative 2035 emissions reduction goal if the government released modelling on interim climate targets.

In a fiery interview on Sunday with Sky's Sunday Agenda host Andrew Clennell, the federal Opposition Leader became defensive after being pressed to reveal the locations and costings of his six proposed nuclear power plants.

Mr Dutton said he would reveal the opposition's energy plan within 'weeks' in March but again declined to spell out the full details of his vision for Australia's energy transition.

'What we've said, the sites that we're looking at are only those sites where there's an end-of-life coal-fired power stations,' he told Sky on Sunday.

'One of the main reasons is that people in those communities know that they're going when coal goes and we have the ability to sustain heavy industry, we have the ability to keep the lights on.'

A recent report from peak scientific body CSIRO suggested that building a large-scale nuclear power plant in Australia would cost at least $8.5bn and take at least 15 years to deliver.

The Coalition has refused to confirm reports of the locations of up to seven proposed power sites, which according to speculation, include sites in two Liberal-held seats and four or five Nationals-held seats.

Potential sites include the Latrobe Valley and Anglesea in Victoria, the Hunter Valley in NSW, Collie in WA, Port Augusta in South Australia, and potentially a plant in the southwest Queensland electorate of Maranoa, held by Nationals leader David Littleproud.

When pressed on the locations of the sites, Mr Dutton responded: 'We've said that we're looking at between six and seven sites, and we'll make an announcement at the time of our choosing, not of Labor's choosing.'

When asked if a power plant would be placed on each of the unspecified sites, Mr Dutton did not answer directly, saying only that he would consider output and environmental impact.

The Opposition Leader was then asked if the plants would be government subsidised, and responded by saying all power sources, other than coal, receives funding.

'We'll make an announcement in due course, but I just make the point that wind and solar don't work without government subsidy,' he said.

Mr Dutton also came under scrutiny this week after revealing he would oppose a legislated 2030 carbon emissions target at the next election.

Asked directly if he would consider a 2035 interim reduction target, which would be legally required under the 2015 Paris agreement, the Liberal leader said he would 'take advice' from the treasury before changing climate legislation, citing concerns about the nation's economic situation.

'I think we have a look at all of that information and if there were settings we need to change ... it doesn't mean exiting Paris or walking away from our clear commitment to be net zero by 2050,' he said.

Mr Dutton was asked for a second time if he would set a 2035 target, but again spoke at length about cost of living pressures facing the country.

Trade Minister Don Farrell said Mr Dutton's comments were 'outrageous' and argued watered down climate commitments would damage Australia's standing with its international allies.

'It's beyond the pale to be perfectly honest,' Mr Farrell said on Sunday.

'We went to the last election committing to a 2030 target and despite what Mr Dutton might say, we're on track to meet that target.'
