The Ministry of Energy envisions an ambitious solar expansion, winter imports, and a few other renewable sources
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
7.5% increase in hydro
Hydro production is increased by 7.5% until 2050
Decomissioning end 2043
Nuclear plants are run close to 60 years, 2043 is last productive year of Leibstadt plant

Challenges
High Import Dependency
Rising import needs after nuclear decomissioning require neighbor surplus and EU agreement
Public opinion
Public opinion needs to accept more hydro plants and higher dams
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
Costs

Levelized cost
We use Levelized costs of electricity (LCOE). Future costs may rise as cheaper plants are replaced. High demand and costly technologies like rooftop PV can further increase costs. See Expert Mode for details on technology costs.
