Solar power plants in the Czech Republic have recorded their strongest month in history so far. According to data published on Energostat, they supplied 701 GWh of electricity to the grid in May, surpassing the previous record set in June 2025 by nearly 50 GWh. Total electricity generation in the Czech Republic rose year on year by just under 200 GWh in May, while consumption was virtually unchanged.

Electricity generation rose despite stagnant consumption, increasing by 3.4 % year on year to 5.62 TWh. Nuclear power plants were traditionally the largest source of electricity, accounting for almost 50% of total generation with 2.6 TWh. Lignite-fired power plants supplied 1.4 TWh of electricity to the grid in May, around 140 GWh more year on year.
