Power struggle: The push for Australia’s coal plants to pay to pollute - The Age

Climate advocates and energy analysts have renewed calls for a carbon price or pollution levy on Australia's coal-fired power plants. The push centres on making the true cost of emissions visible in electricity pricing, with the aim of accelerating coal's retirement and funding clean energy investment. No specific mechanism or timeline has been legislated, but the argument rests on the premise that coal's external costs are currently socialised while renewables bear the full cost of their deployment.

Where this fits

This is a cost-shifting proposal dressed as climate policy. It targets coal's emissions externality but ignores the whole-system costs now embedded in Australia's renewables transition: the battery and inverter supply chain powered by Chinese coal, the transmission overbuild required for weather-dependent output, the gas peaking plants needed for firming, and the rare-earth and lithium footprint. A carbon price on coal alone does not level the playing field; it redistributes cost without addressing the hard dependencies. The policy also defers the question energy realism must answer: if coal is unacceptable on emissions grounds, and a renewables-only grid requires gas backup and transmission duplication, why is the lowest-emission firm alternative, nuclear, barred by law?

What it means

A coal levy would accelerate the closure of dispatchable generation without ensuring the grid has sufficient firm replacement. Australia's experience with coal retirements already shows the pattern: gas plants built at higher cost and lower efficiency than the coal they replace, their firming duty driving up system cost while weather volatility remains. Until Australia legalises nuclear and secures sovereign control of battery and inverter supply chains, a carbon price on coal is a tax on reliability, not a path to affordability.
