‘The sites are ready’: Power giant wants AI data centres built at its coal plants - SMH.com.au

A major Australian power generator has proposed siting artificial intelligence data centres at existing coal plant locations, citing infrastructure readiness and grid proximity. The proposal appears designed to use stranded coal assets and maintain workforce and grid connection after coal retirement.

Where this fits

This move exposes a hard constraint on the renewables-only transition: AI data centres demand firm, continuous power. Coal plants offer that. The fact that a power company is now pitching coal sites as the logical home for data-centre loads reveals what policy has obscured: the grid needs dispatchable generation to run high-value industrial loads. It is a tacit admission that wind and solar alone cannot reliably feed data-intensive work. The proposal also flags that Australia's grid connection infrastructure, built for centralised generation, is being repurposed rather than replaced, a cost that renewables-only accounting has minimised.

What it means

If data-centre development becomes the primary use case for coal plant sites, it signals that Australia will continue burning fossil fuels for baseload power, only under a different business model and customer base. The alternative, deploying firm nuclear generation at those sites, remains legally prohibited, which means Australia will either import data-centre investment (and the jobs and tax that follow), or continue coal operation longer than emissions policy admits. Either way, the grid's dependence on dispatchable power is being confirmed by the market itself, not by ideology. The question is not whether that firm power is needed, but whether Australia will own and control it, or lease it from a shrinking coal fleet while nuclear remains off the table.
