State support needed to make new Swiss reactors viable, report says
- A study by ETH Zurich and the PSI reveals that building new nuclear power plants in Switzerland is currently uncompetitive without state subsidies.
- While advanced reactors are technologically compatible with Switzerland's future solar- and wind-heavy energy system, financial feasibility requires government risk-mitigation measures to lower capital costs.
- The report notes that limiting construction costs to approximately 8,000 CHF/Kw is crucial for nuclear power to effectively reduce winter electricity imports.
