La colonna di destra confronta oggi con il periodo di quella riga. Tutte le medie sono ponderate sulla durata degli intervalli, così i giorni precedenti il 1° ottobre 2025 — quando il mercato funzionava a ore — non pesano in modo errato.

Confronto con i paesi vicini

interconnesso significa che ENTSO-E pubblica un flusso fisico tra le zone dei due paesi — cioè esiste davvero un cavo in cui scorre energia. vicino sulla mappa significa solo un confine in comune. Le due cose non coincidono: Norvegia e Paesi Bassi non confinano, eppure hanno un cavo sottomarino.

Come leggere le cifre di questa pagina

Il prezzo mostrato è il prezzo all’ingrosso del giorno prima: quanto costa l’elettricità in borsa, prima di tariffe di rete, oneri, IVA e margine del fornitore. La bolletta domestica è più alta, e il rapporto tra le due varia da paese a paese e da contratto a contratto.

«Prezzo medio» indica la media ponderata sulla durata di ogni intervallo. Fino al 30 settembre 2025 gli intervalli erano di un’ora; dal 1° ottobre 2025 sono di un quarto d’ora. Una media semplice a cavallo di quel confine peserebbe un quarto d’ora come un’ora.

I giorni del cambio d’ora hanno 23 o 25 ore, e il riepilogo li calcola con la loro durata reale, non con 24 ore presunte.
