The Member for Solomon spent her first day back in the job forcing her own party to backflip, after the NT Government said it wouldn't pass on millions of dollars in savings to Territorians from the scrapping of the carbon tax.
Natasha Griggs described it all as a "misunderstanding".
But she confirmed the new Federal Government would give the Australian Competition and Consumer Commission extra power to make sure the full discount would be passed on once the carbon tax is scrapped.
"The carbon tax components will be taken off the bills and will be passed on to the consumers," Ms Griggs said.
"That has to occur because the ACCC will be given additional powers to make sure.
"It doesn't matter whether it's a government or non-government jurisdiction - those reductions, because of the carbon tax, will be passed on to consumers."
Power and Water figures show that, in this financial year, Territory homes will fork out, on average, between $106 and $234 in carbon tax levies just as part of their electricity bills alone.
The issue blew up this morning after Territory Treasurer Dave Tollner told the ABC that Territorians' power bills would stay the same, even if the carbon tax was abolished.
"What we've said is that there won't be any ... well, what (Prime Minister elect Tony) Abbott said is that there won't be any, ah, ah, carbon tax increases. So that's the best news ever," Mr Tollner said.
He also appeared to suggest the estimated $23 million Territorians paid last year, when the levy was first introduced, didn't actually go towards the carbon tax.
"I know (Territory Opposition leader) Delia Lawrie made some excuse as to why she was putting up power prices with the carbon tax and the like, but that's got to be analysed further," Mr Tollner said.
Ms Lawrie said Mr Tollner had been caught trying to rip Territorians off the day after an election in which his own party promised to reduce power bills by scrapping the carbon tax.
"Dave Tollner often tries to hide behind the fact that he's just dumb," she said.
"But I actually think it's more sinister than that.
"He quite deliberately is breaking a big commitment to Territorians by the CLP when he wants to hang on to any carbon tax (money) that would (otherwise) see power bills reduced at Power and Water."
The Power and Water Corporation has now confirmed the NT Government has told it to pass on the full discount once the tax is scrapped.
"PWC can confirm that advice from (the NT Government) is that when legislation to remove the carbon tax is passed federally, 100 per cent of the carbon tax component will be removed from customers’ accounts," a Power and Water spokeswoman said.
