Swiss electricity production by source

Original title: Elektrizitätserzeugung · Production d’électricité

Switzerland produced 67 522 GWh of electricity in 2025. Hydropower supplied 56% and nuclear power 27%, while other renewables such as solar, wind, wood and biogas reached 9 189 GWh (14%), up from 88 GWh in 1990. Output swings from year to year with rainfall, snowmelt and nuclear plant outages; the highest year on record was 2024 with 81 054 GWh.

Known limitations

Figures are gross production in gigawatt-hours (GWh) per calendar year; net production subtracts electricity used by pumped-storage plants.
Other renewables (wood, biogas, solar, wind) were first recorded in 1990; earlier years show no value, not zero.
Production is not consumption: Switzerland imports and exports electricity, which this table does not cover.
The most recent year can be revised in later editions of the energy statistics.
