The ACT Liberal opposition is standing by the territory's 100 per cent renewable energy target despite a federal government push for states to give up their freedom to set their own goals.
The nation's energy ministers are expected to lock horns over the Turnbull government's push for a single national target during an emergency meeting of the COAG energy council on Friday.
Prime Minister Malcolm Turnbull has accused Labor states of setting aggressive and unrealistic renewable goals, putting the nation's energy security at risk.
But the ACT's 100 per cent target by 2020 has bipartisan support and the Liberal Party insists it's "very comfortable" with the policy.
"We'll stick to our target," Liberal leader Jeremy Hanson told AAP on Thursday.
"The contracts are locked in, it's legislated and we supported that legislation."
The renewable energy debate - reignited by a statewide blackout during devastating storms in South Australia - has escalated into a war of words between SA, Victoria and the federal government.
Victorian Premier Daniel Andrews has accused Mr Turnbull of spinning "ignorant rubbish" and his SA counterpart Jay Weatherill says the Liberal Party is "bought and sold by coal".
Federal Energy Minister Josh Frydenberg has put state and federal renewable targets on the agenda for Friday's Melbourne meeting, saying levels of government needed to "harmonise their goals".
"We want reliable and affordable energy supply as we transition to a lower emissions future," Mr Frydenberg said.
"But at all times energy security is paramount and that is why we need better co-ordination and co-operation between the states, territories and the federal government."
The ACT will achieve its target through reverse auctions awarding 20-year government contracts to renewable providers.
But the renewable generators don't have to be located in the territory and the government has signed contracts with two wind farms in Victoria and one in SA.
That quarantines the territory from any instability when the wind isn't blowing or the sun isn't shining, because renewable energy is expensive to store.
The ACT is also well connected to the National Electricity Market through the NSW electricity grid, unlike SA which only has the two connections with Victoria.
SA relies on wind energy for about 40 per cent of its power and closed down its last coal-fired power station earlier this year.
Mr Weatherill denies this has anything to do with the blackout.
Initial inquiries by the Australian Electricity Market Operator found extreme weather events led to the overload of an interconnector to Victoria, which shut down to protect itself.
Mr Hanson said every state and territory was different and debates in SA and Victoria were a matter for those jurisdictions.
"My interest is in the ACT and what's right for the ACT," he said.
But Chief Minister Andrew Barr told AAP he believes the ACT Liberals would fold to federal government pressure on the target.
