The nation’s independent energy market operator yesterday called for Australia’s fleet of coal-fired power stations to remain in operation for as long as possible.

Extending the operation of this fleet for as long as they are economically viable represents the “ least-cost option” for the next twenty years, according to the recommendation. It is thought the move would ward off any future price shock, as Australia transitions to a more renewables-involved grid.

Deputy Prime Minister Michael McCormack says the report speaks a lot of sense.

“I certainly know that the ACCC report and the AEMO report, they do give hope for investment in coal. Certainly other technologies as well, but coal has to be party of the mix,” he says.

“But we also need to as a nation, know and understand there are some of those coal-fired power stations which could be enhanced, which could be revitalised and expanded. That could also provide a solution if the investment isn’t there for new coal-fired power stations.”

The report and this kind of sentiment is predicted to flare up debate around AGL’s planned 2022 closure of the Liddell power station. McCormack says government should not “ rush in and nationalise things” when it comes to privately operated assets, also reiterating his technologically agnostic stance.

“The ACCC chairman said only last week, that only a technology neutral approach will get prices down. Whenever government prescribes that the technology should be one thing or another, that is when you get higher prices.”
