Is the Coalition's nuclear power plan cheaper than renewable energy?

Australia’s Coalition released a nuclear power policy costing, claiming a $263 billion saving compared to Labor’s renewables-only plan. The Coalition’s Progressive Change scenario involves a slower transition with nuclear power, leading to higher emissions than Labor’s Step Change scenario. Frontier Economics’ report suggests nuclear is cheaper due to delayed coal replacement and longer plant lifespans, but CSIRO and Lazard studies show renewables are more cost-effective.
