Labor says it won't support the Turnbull government's imminent energy policy announcement unless it includes a clean energy target.

The government is putting the final touches on its energy policy, which the prime minister says will address energy affordability and reliability, and meet Australia's emissions target.

It's understood the policy could be discussed at Tuesday's coalition party room meeting in Canberra.

But opposition energy spokesman Mark Butler says Labor, while willing to keep an open mind about a clean energy target as recommended by Chief Scientist Alan Finkel, isn't giving the government a blank bipartisan cheque for any policy.

"What we're very worried about ... is the increasing likelihood that Malcolm Turnbull is walking away from the clean energy target under pressure from Tony Abbott," he told ABC TV on Sunday.

"If that's what he does, then he won't get the support of the Labor Party."

Capitulating to the conservative elements within the coalition who opposed the clean energy target would have real consequences for the economy, including an investment freeze, job losses in the renewables sector, falling electricity reliability and rising power prices, he said.

The government has agreed to 49 of the 50 recommendations from Dr Finkel's review of the electricity market.

However, over the past week it's indicated it might leave the final recommendation, which includes the clean energy target, a requirement for power plants to give three years' notice of closure, and a plan for all governments to agree to a trajectory for reducing emissions rather than just an end level.

Senior minister Julie Bishop said all details of the government's new plan would be made public once cabinet and the party room had signed off.

"Labor and the Greens are undermining energy security and their policies will inevitably lead to higher prices and less reliability for energy," she told reporters in Sydney.

Greens leader Richard Di Natale said he was concerned Labor would feel pressured to accept "whatever shoddy plan the government decides to put to them" after facing bruising campaigns against carbon prices over the past decade.

"It's no question that Labor would rather be fighting an election on other issues but here we are with the government basically saying to them we're walking away from anything that looks like a rational plan," he told Sky News.
