Taxpayers on the hook as Snowy delay threatens Tomago rescue - The Australian

Snowy Hydro 2.0 delays are now threatening to force taxpayers to bail out Tomago aluminium smelter, which faces closure without new firm power supply. The project, central to the government's renewables transition plan, has not delivered the firming capacity it promised on the timeline promised. Tomago's survival depends on securing firm electricity; without Snowy 2.0 coming online as scheduled, the smelter faces either subsidy or shutdown.

Where this fits

This is a live test of whether a renewables-heavy grid can support industrial load without firm power standing ready. Snowy 2.0's delay exposes the cost and timing problem embedded in the whole-system transition: solar and wind are cheap per megawatt-hour, but the firming infrastructure, pumped hydro in this case, runs years late and billions over budget. The article reveals what happens when firming is treated as optional, then becomes emergency: the bill lands on taxpayers, not the energy market.

What it means

Australia cannot run large industrial users on weather-dependent power alone. Tomago needs firm, dispatchable electricity around the clock. When the chosen firming source (Snowy 2.0) stalls, the options narrow to subsidy, closure, or importing aluminium from countries with cheaper electricity, often produced by coal or gas, with no net emissions gain. A nuclear baseload plant would have supplied that firm power without delay, subsidy risk, or the material and transmission overbuilds Snowy requires. Instead, taxpayers face the cost of both the late pumped hydro and the rescue of an essential industrial asset.
