Queensland Energy Minister Mark Bailey has denied covering up a report that outlines the benefits of building a coal-fired power station in north Queensland.

The report was commissioned by the Energy Department and finalised in February but not released publicly.

It suggested a new coal-fired power station could provide a large-scale source of storable, reliable and diversified energy.

The report also identified a range of risk factors, including high carbon emissions, the exposure to export-parity coal prices and the possibility the asset could become stranded.

The LNP supports building a new power station in the north, but Labor has been opposed to the idea.

Mr Bailey said the report was flawed, but that he was only made aware of it yesterday.

"First I knew of this report was yesterday and I can see why it didn't even make it to me because it didn't take into account basic things that are happening in the energy market," he said.

"It was commissioned from within the department, I wasn't briefed on the report ... it's not a significant piece of work, and of course a new coal-fired power station would take seven years to build."

Mr Bailey said he was happy to release the report, but it lacked basic considerations and was not taken seriously.

"It didn't take into account what's going on within the political system, it didn't take into account for instance the plunging cost of battery storage which is changing the energy market," he said.

"It shows that it's only under some very unlikely and extreme scenarios that a new qualified power station could any way be profitable and that under most scenarios it would lose a huge amount of public money."

Questioned on the matter today, Premier Annastacia Palaszczuk said a new power station would take seven years to build and do nothing to reduce the cost of power.

"There are hundreds of reports that get commissioned all the time, yes I am aware of the report," she said.

"The report is very clear, a new coal-fired power station would keep electricity bills high for the next 40 years."

'Secret plan' accusations levelled at both party leaders

Queensland's leaders have already accused each other of having "secret plans" — one to clip a campaign's wings, the other to sell assets.

Opposition Leader Tim Nicholls said the Government may have "nobbled" the start of his election campaign.

Mr Nicholls said travel budget restraints and a lack of available charter planes had kept him in the south-east for the first three days of his campaign.

"It's extraordinarily difficult for us to be getting planes at the moment because of the shortness of the time within which the election has been called," he said.

"There are just not planes available.

"Whether that's part of the Government's plan or not, whether that was part of their secret plan to nobble us, that'll be up to them to answer," Mr Nicholls chuckled.

'Tin-foil hat stuff'

Meanwhile, Premier Annastacia Palaszczuk has made the unsubstantiated claim that her opponent is secretly planning to revisit the LNP's policy to sell assets.

"He would have sold our assets, and I tell you what, they still have a secret plan to sell the assets," Ms Palaszczuk said.

"You cannot trust a man who went to the last election wanting to sell our public assets."

Ms Palaszczuk was asked multiple times if she had any evidence to back it up.

"I would not put anything past him … you can't trust him," she said.

Mr Nicholls scoffed at the assertion.

"It's so secret that even I don't know about it, there is no plan to sell or lease assets, I have been crystal clear on that for a long time," he said.

"This is 'tin-foil hat' stuff from Annastacia Palaszczuk … if she has one skerrick of evidence, if she has one piece of proof, she would be putting it out there.

"This is just like Anna Bligh back in 2012," he said, referring to allegations Ms Bligh levelled against Campbell Newman.

"Fear, smear and no idea."

Public service report

Ms Palaszczuk deflected questions from the media about why a report from consultants KPMG into Queensland's growing public service hadn't been released.

"As I said very clearly, our growth rate is 3.2 per cent and we know that very clearly, people want frontline services in their communities," she said.

"That's why I committed to 400 extra police officers across this state, 53 right here in Townsville."

"When you want to talk about frontline services, go and ask Tim Nicholls which doctors he's going to cut from the hospitals — go and ask him which nurses he wants to cut from the hospitals and which teachers and which teacher aides?"

She said the report was "in the cabinet process".

"Once it goes to cabinet, it will be publicly released," she said.

Mr Nicholls said it was "completely unfair".

"Queenslanders have paid for this report, what is it hiding?

"What should it be telling us about what has happened in the last two and a half years while Annastacia Palaszczuk and Labor have been in charge?

"If we're elected we'll released it straight away."
