The Joint Activity Scenarios & Modelling (JASM) bundles the knowledge of all eight Swiss Competence Centers for Energy Research (SCCER) to generate scenarios, evaluating how Switzerland can substantially reduce its CO2 emissions in the energy sector.

The energy system encompasses all elements required to satisfy our basic energy needs for electricity, heat and mobility services. While today’s heating and mobility sectors use mostly fossil fuels (oil and gas), in the future these sectors will probably undergo an electrification via heat pumps, power-to-gas and e-mobility – the so-called sector coupling. In JASM we try to understand the role of these demand technologies and the low-carbon supply options in the future decarbonized Swiss Energy system. We aim at answering important questions, such as the overall cost of the energy transition, the importance of the various generation technologies and the role of energy storage – both short term and seasonal. Furthermore, the project will result in recommendations for policy measures that can be used to realize the transformation of the energy system.

To answer these questions, we soft link sectoral and full energy systems models to generate physically sound scenarios for a low-CO2 energy system.  The sectoral models of the project partners provide all assumptions regarding the supply side (technology characteristics, hydro power and photovoltaics potentials, etc) and the demand side (space heating, industrial energy demand, etc). These assumptions are fed to a number of full energy system models that simulate the future scenarios of the energy system.
