EDITOR'S NOTE: Battery storage also rated a mention during yesterday's parliamentary inquiry into nuclear energy.

Dr Sarah Lawley, an energy professional, has given evidence to the inquiry,  warning the national grid is at times struggling to handle the volume of solar power being produced.

Dr Lawley says the rollout of large-scale storage batteries still won't meet the oversupply issue.
