We unlock the flexibility potentials of the Swiss energy system.

We ensure supply security and social acceptance in a renewable-based future, supporting decision makers with energy investments.

The future decarbonized energy system is expected to increasingly rely on electricity. This will require advanced flexibility mechanisms along the entire electricity supply chain as well as new technical solutions outside the electricity sector. Seasonal energy storage and demand-side flexibility measures that are acceptable to the consumers are needed to reduce stress on the power system.

We analyse the coordinated deployment of flexibility options in light of the 2050 net-zero emissions target on Swiss national and local/regional scales. The competences of several established modelling teams of the ETH Domain are combined to perform an integrated model-based scenario analysis.

Beyond techno-economic modelling, socio-economic research is used to investigate the preferences of consumers for new energy supply systems and the feasibility of demand-side flexibility options.

Technology roadmaps and geo-spatially detailed maps of flexibility mechanisms will inform decision makers, stakeholders, and citizens about necessary future investments and technology prospects for a carbon-free Swiss energy system.

The goals of this Action Area include determination of the following:

  • Energy system flexibility needs at a national level.
  • Distributed energy/H2 storage options at a GWh scale.
  • Preferences for new energy systems and demand flexibility.
  • Energy supply, demand and flexibility at a building scale.
  • Energy supply, demand and flexibility at a municipality scale.
