This report describes the energy grid model couplings between the FlexECO grid models of ETHZ with other models used within the SURE framework. The coupling is essential to compute electricity and gas grid security indicators for all SURE pathways and shock scenarios. The first quantitative results show, how the Swiss high voltage electricity grid loading will increase in future years during hours of high load and how pressure shocks propagate through the gas network to critical levels after the activation of gas power plants.
