The State Government denies the flooding of the Yallourn coal mine could have been prevented by more thorough Government oversight.
The plant's operator, TRUenergy, says the power station will increase its output this week as more generators come online.
Only one of the four generators has been operating since the Morwell River burst its banks two weeks and floodwaters swamped coal conveyers.
Victoria's Energy Minister, Michael O'Brien, says the Department of Primary Industries is overseeing TRUenergy's response.
"Certainly we will be investigating to work out the causes of it and to work out whether the structures that were in place were up to standards, and if not what lessons can be learnt for the future," he said.
"But certainly when natural events of that magnitude occur, I don't necessarily know if there's anything that any particular department can do to prevent that."
