Uncertainty over coal plant closure dates is weakening investor confidence in renewable energy, creating a circular problem where coal stays open because new investment is delayed.

The failure of state and federal governments to set and adhere to firm end-dates for coal-fired power generation around Australia remains a thorn in the side of the renewable energy transition, industry says, creating investor uncertainty and suppressing the ability to attract the capital necessary to fund the shift.

Black and brown coal generators still make up more than 42 per cent of Australia’s the electricity supply, with four coal plants still dominating the mix in New South Wales, three in Victoria, eight in Queensland and three in Western Australia.

And repeated delays and uncertainty over future changes is now cited as one of the main, if not the main, issue haunting the backers of new renewable developments.

On top of this, state governments have shown a propensity to intervene in coal plant retirement timelines, most notably in New South Wales and Queensland, where the abject political fear of “the lights going out” has led to public spending on keeping coal clunkers........
