The Northern Territory Opposition Leader says the Government is using price hikes to prepare the Power and Water Corporation for a sell-off.
Delia Lawrie claims the Country Liberals Government is preparing to sell the utility to Energex in Queensland, which is headed by former Country Liberals chief minister Shane Stone.
The Labor Opposition has also raised concerns that Ken Clarke, who is on the Government's budget review panel, is an Energex board member, alongside Power and Water board members Merv Davies and Linda Mackenzie.
Ms Lawrie says the Chief Minister Terry Mills wants to privatise the utility.
"He is fattening the pig for sale at market," Ms Lawrie said.
"He wants to sell off Power and Water, privatise the utility.
"And no coincidence that his old mate Shane Stone heads up a private company in Queensland and has Ken Clarke, who's advising Terry Mills on Power and Water, on the board of Energex in Queensland." But the Treasurer Robyn Lambley says the price rises have nothing to do with a plan to privatise.
"Absolute nonsense," Ms Lambley said.
"It is so far off the table it is not even worth talking about.
"No one in their right mind would buy the Power and Water Corporation.
"It is bordering on insolvency at the moment and that is why we've had to make these difficult decisions just three months into Government."
