NSW Premier Barry O'Farrell believes Prime Minister Julia Gillard's proposals to ease power prices will be approved at Friday's Council of Australian Government (COAG).
Ms Gillard plans to pitch several measures to state premiers to save consumers up to $250 a year on their energy bills.
The states will be asked to boost competition in their electricity markets and consider introducing smart meters and cost-reflective pricing so consumers can better manage their energy usage.
Mr O'Farrell is optimistic the measures will be approved.
"The prime minister's package will get through if for no other reason that it doesn't deliver anything until after the next federal election campaign - and who knows who will be prime minister then," he told ABC Radio.
Mr O'Farrell said the prime minister's proposals would not cut power prices much but would help people avoid power costs.
He says the best way to cut power prices would be to wind back the carbon tax and other green schemes.
Queensland premier Campbell Newman said he wanted an agreement that put a real brake on electricity prices.
"I raised this as a national issue many months ago," he told reporters in Canberra.
"I am keen to see the commonwealth do what they need to do, which really centres around the national energy regulator."
Mr Newman said he had already taken action to slow the rise in electricity prices in Queensland.
His Victorian counterpart Ted Baillieu said his state was the model for reform in the energy sector.
Mr Baillieu said the national energy regulator needed the authority, power and resources to function properly.
"It will be a matter for the other states, but we would observe that the regulator needs to be separated from the ACCC (Australian Competition and Consumer Commission)," he said.
"We will wait and see, the commonwealth seems to have a slightly different view on that."
South Australian premier Jay Weatherill also said the regulator's powers needed to be strengthened.
"What we want is a regulator with teeth that has the capacity to make decisions that won't be overturned in court," he said.
"We need to give them backup so when they apply a decision, it is able to be sustained."
