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.

OMIE publishes Portugal’s day-ahead periods in CET/CEST. The clock labels on this page follow that market convention and are one hour ahead of mainland Portugal civil time.

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.
