The NSW government and NSW Labor had both lobbed a series of bombs before the two sides steam into the final four weeks before the state election.
NSW Premier Dominic Perrottet and his Treasurer Matt Kean attacked Labor leader Chris Minns after he said his energy plan could take six to seven years to deliver bill relief.
"I'm going to be honest ... the benefits of this policy will be felt six or seven years down the line," Mr Minns told Sky News on Friday.
Labor has committed to creating a $1 billion state-owned renewable energy corporation to address issues with renewable energy capability, and manage the state's transition away from fossil fuels.
The government called the interview a "train wreck", with Mr Kean saying Labor would not deliver if elected at the March 25 poll.
"It's a relief that the Labor mask is falling away and the policy and budget black holes are being revealed before it's too late," the treasurer said.
The government has offered households a one-off $250 energy relief voucher if they are re-elected at the upcoming election.
The premier said the short-term relief and the government's long-term economic plan was at risk.
"Seven years. That's not even in the next term of government," he said.
Mr Minns later expanded on his comments, saying energy bill rebates were due later this year as part of the federal government's intervention into the energy market.
"That will happen regardless of who wins the state election," Mr Minns told reporters on Friday.
"We've made a call that we need to look at long term reform to energy markets in NSW, so that we don't keep falling back into the cycle where bills explode for industry, companies and households."
"The government's made a decision to use a one-off cash splash for one year only," he said.
It comes after Prime Minister Anthony Albanese used a rare outing on the NSW election campaign to attack the NSW government, calling its members a "rabble".
While noting he got on well with Mr Perrottet and all state and territory leaders, he said the NSW government was focused on its own squabbles.
"The problem for Dominic Perrottet is that he leads a rabble ... that is disunited, that is too busy fighting each other to fight for the people of NSW," Mr Albanese said.
"That stands in stark contrast with Chris Minns and his team."
The prime minister said it was extraordinary the premier had not been able to nominate replacements for ministers retiring at the election, suggesting this was due to recent internal chaos, sparked by the party seeking to replace a vacancy in its upper-house ticket.
"It's time for a government that is united where the premier and the leader can speak on behalf of the government without having to watch their back the whole time," he said.
