Czechia among Europe’s most nuclear-reliant countries in 2025

Czechia’s nuclear power plants at Temelín and Dukovany produced a record 32.066 terawatt-hours (TWh) of electricity last year, the highest annual output to date. The figure would cover roughly half of the country’s annual electricity consumption. Daniel Beneš, CEO of ČEZ, said the milestone was achieved through longer fuel cycles and gradual, safe power uprates at both plants. Nuclear energy accounted for more than 40 percent of domestic electricity production. Output is expected to be slightly lower this year due to planned maintenance outages. Preparations are also continuing for two new reactors at Dukovany, to be built by KHNP.
