Un'economia domestica media che consuma 4'500 kilowattora pagherà in media 62 franchi nel 2016 per l'uso della rete elettrica, esattamente come quest'anno. È il 7% circa dei costi annuali dell'elettricità, comunica Swissgrid, che ha deciso di lasciare invariate le sue tariffe.
La cifra potrà fluttuare in funzione del fornitore, precisa l'impresa che gestisce la rete. Si compone di due elementi, che andranno a compensarsi a vicenda: per l'uno è previsto un incremento del 14%, per l'altro una riduzione del 17%.
A più lungo termine, un rincaro è già preventivato: servirà a finanziare l'ammodernamento e l'estensione previsti nel corso del prossimo ventennio, volti a colmare lacune note da tempo. I costi sono stimati in 4-6 miliardi di franchi.
