Nel 2024, l’azienda energetica della Città di Zurigo EWZ ha prodotto il 30% di energia idroelettrica in più rispetto al 2023 nel Canton Grigioni, grazie a un anno più piovoso. Gli impianti nei Grigioni centrali hanno generato 863,2 gigawattora, quelli in Bregaglia 516,9. Insieme rappresentano metà della produzione totale di EWZ, che ha pubblicato il rapporto annuale.
EWZ ha discusso il rinnovo delle concessioni nei Comuni di Bregaglia e Surses. In Bregaglia, è stato sviluppato un modello di partecipazione agli utili con le autorità comunali, mentre a Surses la popolazione ha rifiutato il rinnovo, preferendo seguire la strategia cantonale, che prevede il passaggio degli impianti sotto il controllo del Cantone e dei comuni.
Il potenziamento della diga di Marmorera (innalzamento di 14 metri), è legato proprio alle nuove concessioni a Surses e “per capire come procedere è necessaria una rapida decisione per chiarire i rapporti di proprietà e dei diritti idrici”, si legge nel comunicato
