Cost of ad-hoc nuclear policy uncertainties in the evolution of the Swiss electricity system

► Development of a Swiss TIMES electricity model and long-term scenarios analyses. ► Short-term demand can be cost-effectively met with new investment in gas-fired generation capacity. ► In the medium and long run, nuclear represents the most cost-effective option. ► All non-nuclear electricity supply options increase the cost of electricity supply by between 50 and 150%. ► It is difficult to avoid an increased reliance on imports of gas or electricity.
