Green goal in doubt as Victoria pauses $1.5b cable - afr.com

Victoria has paused a $1.5 billion interconnector cable project, throwing doubt on the state's emissions reduction targets. The pause signals a halt to planned grid infrastructure needed to support the renewable energy build-out across southeastern Australia.

Where this fits

This is a cost and reliability pressure point. A renewables-heavy grid requires not just panels and batteries, but an overbuild of transmission and interconnection to move power across regions when local wind and solar output fail to meet demand. The pause reveals that even state governments are discovering the true system cost: a $1.5 billion cable that sits idle most of the year, earning minimal revenue, is hard to justify politically or economically. Firm dispatchable generation, built once, dispatched on demand, no transmission overbuild needed, avoids this friction entirely.

What it means

Victoria's pause exposes a structural flaw in the renewables-only transition: the grid needs firm power to fill gaps, but to get there via renewables alone requires vast transmission infrastructure that carries power only when weather permits. That infrastructure has a hard economic ceiling. State governments will keep hitting this limit, delaying projects, stretching timelines, and raising whole-system costs. Australia is betting the grid's reliability on weather-dependent generation and interstate cables that are chronically hard to fund. A low-carbon firm alternative, nuclear, remains banned by law, leaving the transition path narrower and more costly than it needs to be.
