July heat raised Czech electricity prices. Solar hit record output

The average electricity price on the Czech day-ahead market reached nearly 110 EUR/MWh in July, around 22% higher year on year. Prices rose despite record output from solar power plants and significantly higher generation at nuclear power plants, while electricity consumption remained virtually at last year's level. This follows from data available on Energostat.

The average spot electricity price in July was the highest since 2022, when the market was significantly affected by the European energy crisis. Compared with July last year, it increased by nearly 20 EUR/MWh, while it was more than 40 EUR/MWh higher than in 2024.

Domestic electricity consumption reached 4.70 TWh in July, only around 10 GWh more than in the same month of 2025. Alongside high temperatures, prices were therefore likely driven primarily by regional conditions, limited availability of dispatchable sources and higher natural gas prices, which feed into the costs of gas-fired power plants.
