Decline in output from Czech coal-fired power plants halted last year, but is set to continue

Czech lignite- and hard coal-fired power plants supplied just under 24 TWh of electricity to the grid last year, matching their output in 2024. However, this represented a 28% decline compared with the crisis year of 2022. Total net electricity generation in the Czech Republic increased despite stagnant coal-fired generation, mainly thanks to record electricity output from nuclear power plants. This follows from a comprehensive report on the Czech power sector in 2025, published this week by oEnergetice.cz

Conventional power plants, which for the purposes of the report include nuclear power plants, coal-fired power plants and natural gas-fired power plants, have long generated more than 80% of electricity in the Czech Republic. This was also the case last year, when these sources accounted for 81% of net electricity generation.

Nuclear power plants supplied 30.3 TWh of electricity to the power system in 2025, representing an 8% year-on-year increase. Gross generation at nuclear power plants even slightly exceeded 32 TWh, a historic record. Electricity generation from coal-fired power plants was virtually unchanged from 2024, reaching 23.7 TWh. This was 28% lower than in the crisis year of 2022.
