Solar, hydro and imports
The BFE scenario covers rising demand with solar, hydro and imports

Imports increase
In spite of solar and hydro build-out import dependency will increase

Solar build-out, accelerating 2040
Solar build-out with focus on roof-top, limited addition of alpine PV

          High Import Dependency
          Rising import needs after nuclear decomissioning require neighbor surplus and EU agreement
          people
          Public opinion
          Public opinion needs to accept more hydro plants and higher dams
          energy_export
          High summer surplus
          Summer surplus rises from 9 to 18 TWh in 2050. Unclear how much of it can be exported.

          Additional costs possible
          If summer surplus cannot be exported, the costs per MWh would rise

          BFE
          The Swiss Federal Office of Energy (BFE) is responsible for shaping Switzerland's energy policy. Its Energy Perspectives 2050+ scenario outlines possible paths to a sustainable energy future, focusing on reducing fossil fuel use and increasing renewable energy production to meet climate goals.
