Czechia Wind, Solar and Electricity Prices, 2026
In Czechia, across 396 days from 2025-09-25 (25 September 2025) to 2026-10-27 (27 October 2026), the average day-ahead price on the quarter of days with the highest wind and solar share was EUR 98.35/MWh, against EUR 121.87/MWh on the quarter with the lowest share (EUR 23.52/MWh lower). The correlation between the two is -0.27, a weak tendency for days with more wind and solar to have lower average prices. Prices are day-ahead, in EUR per MWh as published, and are not converted. Correlation is not causation.
Key Facts
- In Czechia, across 396 days from 2025-09-25 (25 September 2025) to 2026-10-27 (27 October 2026), the average day-ahead price on the quarter of days with the highest wind and solar share was EUR 98.35/MWh, against EUR 121.87/MWh on the quarter with the lowest share (EUR 23.52/MWh lower). The correlation between the two is -0.27, a weak tendency for days with more wind and solar to have lower average prices.
- Wind and solar averaged 8% of daily generation in Czechia over 396 days from 2025-09-25 (25 September 2025) to 2026-10-27 (27 October 2026), and the average day-ahead price over those days was EUR 116.00/MWh.
- The quarter of days with the lowest wind and solar share (1% to 4% of generation) averaged EUR 121.87/MWh; the quarter with the highest share (13% to 19%) averaged EUR 98.35/MWh.
Windiest and Least Windy Days
396 days, 2025-09-25 to 2026-10-27| Days | Number of days | Wind and solar share | Average day-ahead price |
|---|---|---|---|
| Highest share quarter | 99 | 13% to 19% | EUR 98.35/MWh |
| Lowest share quarter | 99 | 1% to 4% | EUR 121.87/MWh |
Days are ranked by wind plus solar as a share of that day's generation. The average is the mean of the daily average day-ahead prices. These are daily figures and say nothing about individual hours.

Average Price by Wind and Solar Share
EUR/MWh, days in five equal groups| Lowest fifth of days (1% to 3%) | |
|---|---|
| Second fifth (3% to 6%) | |
| Middle fifth (6% to 10%) | |
| Fourth fifth (10% to 14%) | |
| Highest fifth (14% to 19%) |
Each bar is the average day-ahead price on one fifth of the days, from the fifth with the lowest wind and solar share to the fifth with the highest. A bar at zero width is a price at or below zero. Bars are drawn from zero.

What the Correlation Says
The Pearson correlation between the daily wind and solar share and the daily mean day-ahead price in Czechia is -0.27 over 396 days: a weak tendency for days with more wind and solar to have lower average prices. Among the 39 zones on the main page, it ranks 20 from the strongest negative link.
Correlation is not causation. Season, weather, demand, gas prices and imports all move at the same time as wind and solar output, so this figure describes how the numbers moved together in this window, not what wind and solar caused. It uses daily averages only.
