Prezzo Unico Nazionale

Pubblicato il 27 giugno 2018 alle 11.45


Il PUN, Prezzo Unico Nazionale, è il prezzo di riferimento dell’energia elettrica acquistata in borsa. Le offerte economiche delle aziende fornitrici nascono tutte dalle analisi basate su di esso.

La borsa elettrica italiana (IPEX), è il mercato all'ingrosso dell'energia elettrica dove i produttori di energia elettrica o i trader vendono l'energia all'ingrosso e dove i fornitori del mercato libero, i grandi consumatori e l’Acquirente Unico acquistano l'energia per se stessi o da fornire a terzi.
Il prezzo di scambio è definito per ogni ora di ogni giorno sulla base dell'incontro tra domanda e offerta. Di conseguenza il PUN che va a formarsi è variabile con valori tendenzialmente più alti nelle ore in cui è più difficile e costoso produrre energia mentre presenta valori più bassi nelle ore di maggior offerta/produzione. Il valore del PUN è pubblicato dal Gestore dei Mercati Energetici ( GME ;) che ne dà la definizione seguente:  media dei prezzi zonali del Mercato del Giorno Prima (MGP) ponderata con gli acquisti totali, al netto degli acquisti dei pompaggi e delle zone estere. 

Sempre in funzione dei consumi per fasce orarie, viene stabilita una media prezzo che è indicata in €/MWh (Mega Watt ora) dove un MWh sta per 1000 KWh. In questo modo si determinano i prezzi da applicare ai consumatori finali che hanno stipulato contratti indicizzati e cioè che seguono gli indici di mercato. A questi prezzi i fornitori di energia elettrica applicano uno spread che varia a secondo delle offerte, dei servizi proposti e dalle fonti di provenienza. Quindi le offerte dei contratti luce del mercato libero, così come le tariffe per il mercato della maggior tutela, tendono a salire nei periodi in cui cresce il PUN ed a scendere quando il PUN decresce. 


Negli ultimi anni il PUN ha fatto registrare un forte calo dei prezzi per l’effetto combinato di una serie di motivi. I principali possiamo ritrovarli nel calo dei consumi di energia elettrica, nell'incremento della produzione da fonti rinnovabili e la riduzione del prezzo del gas italiano ai livelli degli altri stati europei.


Contattaci per qualsiasi chiarimento e capire al meglio quale offerta è migliore secondo l'andamento del PUN.
