Electricity generation in Slovakia
Annual electricity production, fuel mix and historical observations for Slovakia, with links to its grid operators, electricity market and power stations.
Reference year: 2024. Published snapshot, not live output. Energy is reported in terawatt-hours (TWh).
How much electricity does Slovakia produce?
Slovakia reported 29.5 TWh of domestic electricity generation in 2024. Among the reported source categories, nuclear produced the most electricity: 18.2 TWh.

Electricity mix 2024
Annual generation by source · terawatt-hours (TWh)
Missing categories are labelled “No data”. Rounding can cause small differences from the reported total.
Renewable share uses domestic generation as its denominator. Low-carbon generation includes renewables and nuclear; nuclear is not renewable. Missing fuel categories remain “No data”, and rounded source values need not sum exactly to the reported total.
Generation is not consumption or installed capacity
The source separately reports electricity demand of 26.6 TWh for 2024. Domestic generation is not electricity consumed after trade and losses. The demand series is a separate source measure, not a calculated import balance. Power-plant ratings in megawatts (MW) measure capacity; annual production in TWh measures energy.

Every row retains its own reporting year. 2024 remains the common-year comparison even where a newer observation exists. Missing observations are not interpolated.
