Utilities push overlooked coal sites for data centres’ ground zero - The Australian

Australian utilities are pitching coal-fired power station sites to data centre operators as locations for new facilities, positioning retired coal infrastructure as ready-made hubs for the energy-intensive computing demand expected to surge with artificial intelligence deployment.

Where this fits

This move exposes a hard constraint the electricity transition has not solved: firm power. Data centres need reliable, round-the-clock electricity. Utilities recognise that coal sites offer not just land and grid connection, but the one thing a renewables-only grid cannot provide without massive cost: dispatchable generation. The story sits at the intersection of cost and reliability. It shows that even as Australia mandates coal exit, the grid's actual users, not ideological planners, are gravitating back to the sites where firm power lives. This is the hidden bill the transition keeps deferring: you cannot run data centres on weather-dependent generation without either massive overbuild in batteries and transmission or accepting frequent curtailment and price spikes.

What it means

Data centres represent Australia's chance to capture value-add jobs and export revenue from its energy endowment. But they will only locate where power is firm and cheap. By closing coal plants without replacing their dispatchable output with equivalent firm capacity, and by keeping nuclear banned, Australia is forcing data centre operators to choose between accepting grid instability or building their own firming (usually gas, which inflates carbon footprint and operating cost). The sites themselves may well host zero-carbon generation eventually. But without firm power on the grid, or permission to build it, Australia risks losing the tenants to countries that have both.
