IT WILL be at least a month before power supply in Tasmania's bushfire- affected areas is fully restored as the state's electricity retailer counts the costs of repairs.
More than 600 poles and 20 kilometres of power lines have been destroyed in the state's south-east between Forcett and Dunalley.
Aurora chief executive Peter Davis said the company would meet the Tasmanian Economic Regulator, who determines how much it can charge customers, once the cost of repairs was known.
"It's very clear it runs into many millions of dollars, but our focus at the moment is purely on doing the restoration. We're doing it as quickly and efficiently as we can, but there's no doubt this is a very expensive exercise," Dr Davis said.
Dr Davis announced a $1.3 million emergency relief package yesterday, which clears any outstanding amounts owing by customers who lost their homes in the fires.
Aurora will also wipe $260 off bills of customers who have been without power for at least 16 hours.
Mobile generation units will provide a temporary source of power in the area from this weekend, as work continues to repair the two main lines into the area.
However, Dr Davis warned it would be some time before more remote customers were reconnected.
"There will be many customers who will remain without power for an extended period, which could be several weeks," he said.Electricity supply infrastructure has also been damaged by the Lake Repulse fire.
