§ How can we keep lights on § Dispensing with Nuclear § Intermittent resources § Peaking and shortfalls
§ ‘How can we affordably minimise intermittency risks, given dispatch possibilities and potential (daily and seasonal) generation?’

Calliope dispatch model of Switzerland 2014
§ Calibration § Switzerland:
§ 2 main regions § Demand of 2014
§ Switzerland § Italy § France § Germany

§ Variant E: § Reduction of electricity demand
(-12.6% per capita) § No electricity from nuclear § CHP will count for 90% of fossil

§ Detailed analysis of high time resolution § Even with high development of REN
§ Switzerland will have to rely on imports § The peak of demand at evening will not be covered by REN
§ The e-production of Switzerland will be highly decreased § Assure the dispatchability with 2 complementary
scenarios of renewable energy § CSP from Nord Africa § Wind from Nord Sea
