Power and Water Corporation has revealed Northern Territory utility bills will rise by almost 10 per cent on July 1, mostly due to the carbon tax.
Managing director Andrew Macrides told budget estimates hearings how much the carbon tax will affect power and water bills.
"For electricity, it is about a 7 per cent increase in the tariff," he said.
Power and Water has also factored in a 2.8 per cent increase due to inflation.
For an average power bill of $2,000 a year, there will be a total increase of about $182.
Mr Macrides says water bills will rise 0.9 and sewerage will increase by a negligible amount.
He says power bill increases will be lower in the Territory than elsewhere because gas fuels 90 per cent of its electricity, compared to higher emitting coal-fired power stations in southern states.
