The Swiss-Energyscope (SES) model has been developed with the aim of enabling Swiss citizen to understand the challenges of the energy transition so that they can make informed decision, in particular during popular votes. SES is a mixed-integer linear programming (MILP) optimization model. Given the end-use energy demand, the efficiency and cost of energy conversion technologies, the availability and cost of energy resources, the model identifies the optimal investment and operation strategies to meet the demand and minimize the total annual cost or CO2 emissions of the energy system. It is a simplified, yet complete, representation of an energy system, including electricity, heating and mobility, with a multiperiod formulation accounting for seasonality and energy storage.
The model is publicly available here.
- Technologies: Investment and operation costs, efficiencies; and emissions
- Resources: Costs and emissions; and yearly availability
- Energy demand
- Electricity production: Technology sizing and operation
- Heat supply: Centralized vs. decentralized
- Mobility: Use of different technologies and modes
ETH developmentThe SES (ETH) is a branch of the original SES model including:
- 24 typical days with 3 hours resolution, this allows for complementary analyses of peak and daily storage issues (for electricity and heat)
- and a more detailed representation of domestic heating systems with different archetypes
