New powers for regulators to monitor electricity and gas markets will be examined by a crisis meeting of energy ministers as senior executives say power price spikes will persist through winter until malfunctioning coal-fired generators can be brought back online.

Nuclear for Climate Action CEO Robert Parker, a former president and vice president of the Australian Nuclear Association, told Liam Bartlett on 6PR Mornings there is a clear focus on why Australia needs the debate on climate change.

"People thought there would be some smooth transition to zero carbon electricity, but that was never going to be the case," he told Bartlett on World Ocean Day.

"We propose a system with about three quarters nuclear, about 17% solar and about 7% hydro, that would come in at about half the cost, using small nuclear power plants or large plants too, a hybrid system, it really comes down to the timing and how quickly you want to take this through transition to zero carbon."
