Nuclear ban risks affordable energy goals, expert warns - news24.com.au

An energy expert has warned that Australia's constitutional and legislative ban on nuclear power is hindering efforts to meet affordability goals in the electricity transition. The expert, quoted in the article, argues that nuclear should be part of the generation mix to help manage costs as the grid decarbonises.

Where this fits

Australia is pursuing a renewables-dominated grid without access to the one firm, low-emission, low-material alternative that operates at scale globally. Nuclear is banned by law. This constraint tightens the affordability problem because a renewables-only path requires massive investment in firming capacity (gas plants, battery storage, or both), grid augmentation to handle distributed intermittent supply, and critical minerals for batteries and inverters. Each of these layers adds cost that a mixed system with nuclear baseload would avoid. The expert's warning names the trade-off directly: pursue renewables alone, or open the generation mix and reduce whole-system cost.

What it means

Australia is choosing an expensive path to decarbonisation. A renewables-heavy grid needs either sufficient gas capacity standing idle to fill generation gaps, or storage infrastructure at scales and costs that remain unproven in Australia's climate and geography. Both options push up electricity prices. Nuclear plants, by contrast, run at high capacity factors for decades with minimal fuel cost and no weather risk. The ban forecloses this option. Australia's energy security and competitiveness depend partly on affordable power; the expert's caution is that ruling out firm generation on principle, rather than on evidence, is a self-imposed constraint that voters and policymakers are not yet explicitly choosing.
