Acknowledging the imminent price hike, energy minister Chris Bowen says it will take time to implement the government’s plan to transition to renewables and shore up the energy grid.

“It will take a while for our policies to work. I think people understand you don’t fix 10 years of neglect in 10 days,” he said on Thursday.

“We have to build 10,000 kilometres of transmission wires to get our system up and running. You don’t do that in six months, you don’t do that in a year.”

Bowen also criticised the former government for delaying news of a power price hike come July 1 until after the election.

“The old government sat on that prior to the election. It had to be released under the new government, the news that energy bills were going up,” he said.

“The old government knew about it but didn’t do anything to get the figures out before the election, surprise, surprise.”

The Liberals have criticised Labor for telling Australians their power prices would come down if they were elected.

“The sense of panic that’s out there from Chris Bowen at the moment wasn’t there when the coalition was in government,” Opposition Leader Peter Dutton said previously.

“What’s happening with the economy at the moment – I mean it always happens on Labor’s watch.”

The suspension of trading in the national energy market will be eased from Thursday morning after the market operator indicated there would be enough capacity for homes and businesses.

Following a “clear improvement” in energy conditions, the Australian Energy Market Operator said it would begin a staged process that would bring the market back to normal.

The system was destabilised last week, prompting AEMO to take control to stabilise power supplies.

The energy market was able to start setting prices again from 4am on Thursday.

The market operator can then completely lift the unprecedented trading suspension after monitoring conditions for 24 hours.

Market operator chief executive Daniel Westerman said there would be a step-by-step approach in lifting the suspension of the market.

He said there had been vast improvement to the market, with about 4000 megawatts of generation being returned to the energy grid after outages.

“That means the risk of any shortfall has reduced markedly,” Westerman said.

“We know many generators are working hard and closely with governments to improve the confidence of their fuel supply, to ensure that they are able to operate at their desired level of output.”

The market operator said it expected the system used to schedule energy generation into the grid would be operating without failure.

This was due to a low volume of directions to generators and a reduction in forecast shortfalls of energy as electricity suppliers respond to market signals.
