The useful conclusions
Lower-cost hours occurred mainly in the middle of the day, although the exact window still changed by season.
The evening was consistently the highest-cost period. The recurring maximum was 17:00–18:00 in winter, 20:00–21:00 in spring, 20:00–21:00 in summer and 19:00–20:00 in autumn.
The lowest seasonal average was Summer at 9.13 ct/kWh; the highest was Winter at 12.11 ct/kWh. The lower figure was 24.6% below the higher one.
The clearest negative-price period was around 13:00–14:00 in Spring, when 39.1% of covered delivery time had prices below zero.
Using these seasonal recurring averages, moving 1 kWh of flexible daily use from each season’s highest hour to its lowest would represent about €43 over the covered days in the wholesale component. This is a historical illustration, not a guaranteed bill saving.

How this profile is calculated
Only published complete days are included. Every source interval is weighted by its duration and grouped by its delivery-start hour in the market’s local time. Missing and repeated daylight-saving hours remain as observed. No prices are estimated.
02 /
Lower cost does not mean an off-peak tariff
For each chart, the six hours with the lowest historical averages form the lower-cost band and the six highest form the higher-cost band. These are observed wholesale patterns, not supplier tariff periods or a prediction of future prices.
