Labor has questioned new modelling showing a $120 a year saving on power bills under the Turnbull government's proposed national energy guarantee policy.
But Energy Minister Josh Frydenberg says the expert advice can be trusted and will give new momentum to striking a deal with the states and territories on prices, reliability and cutting emissions.
Average household bills under the guarantee are tipped to be $120 lower between 2020 and 2030 compared to a "business as usual" approach, where the renewable energy target runs out as planned and is not replaced.
The Frontier Economics modelling, commissioned by the Energy Security Board, is being distributed to premiers and chief ministers ahead of a COAG Energy Council meeting in Hobart on Friday.
It expects wholesale power prices will be 23 per cent lower than "business as usual" between 2020 and 2030, including 30 per cent less in 2030.

The modelling also confirms initial advice that the guarantee would ensure Australia's emissions target of 26 per cent below 2005 levels by 2030 would be met.
"I defy you to find me anyone who thinks energy prices were lower than two or three years ago, who thinks their gas prices are going down not up," Labor leader Bill Shorten told reporters in Brisbane on Wednesday.
"Mr Turnbull has to stop caving in to the right-wing knuckle draggers of the LNP and get on board the renewable energy bandwagon."
Mr Frydenberg said he hoped all governments and parties could work together.
"I'm confident we can get momentum on this policy because users of power ... have all made it clear the last decade - which has seen climate and energy policy become a political football - has not served their interests," he said.
However he added: "Unfortunately for the Labor party they see high emissions reductions targets and high renewable energy targets as ideological ends in themselves."
The national energy guarantee requires electricity retailers to make a certain amount of power available at all times to guarantee reliability, while also guaranteeing certain levels of emissions to help the government meet its Paris accord target.
The modelling also showed small businesses could save hundreds of dollars on their power bills while large energy users such as factories could benefit to the tune of $1.4 million and very large users $10 million a year.
