Czech nuclear power plants generate record 31 TWh of electricity in 2025

Czech nuclear plants Temelín and Dukovany have generated over 31.02 terawatt-hours (TWh) of electricity this year, setting a new annual record. Increased output is attributed to fuel cycle adjustments and plant modernization, ČEZ spokesman Ladislav Kříž said.

This year’s production surpasses 2022’s record of just over 31 TWh, with nuclear power now contributing more than 40% of the country’s electricity.

Dukovany now operates on an extended 16-month fuel cycle, while Temelín will complete its transition next year. Future production will depend on the number of plant outages, with higher outages lowering annual output.
