Output from Czech coal-fired power plants rose 85% in June due to higher prices

Electricity generation in the Czech Republic rose year on year by more than 1 TWh to 5.66 TWh in June. Growth was driven primarily by lignite-fired and nuclear power plants, while solar sources generated only slightly more than last year. Despite a hot end to the month, electricity consumption increased only marginally, with the main impetus for higher generation coming from the spot market and tight conditions in the region. According to data published on Energostat, electricity generation in the Czech Republic reached 5.66 TWh in June. Compared with June 2025, when it stood at 4.51 TWh, this represents an increase of 1.15 TWh, or more than a quarter. This substantial year-on-year growth was not driven by renewable sources, but primarily by higher utilisation of conventional power plants.

The largest contribution to growth came from lignite-fired power plants, which supplied 1.44 TWh of electricity to the grid. This was around 660 GWh more year on year. Nuclear power generation increased from 2.12 TWh to 2.52 TWh, or by just under 400 GWh. Together, these two sources account for the overwhelming majority of the overall year-on-year increase in generation.
