Se i tempi previsti saranno rispettati, nel 2030-31 la diga innalzata del Sambuco dovrebbe entrare in esercizio.
Ancora molta acqua ha da passare sotto i ponti, ma il progetto - che figura tra i 15 prioritari identificati dalla "Tavola rotonda per l’idroelettrico" promossa dalla Confederazione - è ben avviato. Lo hanno spiegato martedì in conferenza stampa a Bellinzona i consiglieri di Stato Christian Vitta e Claudio Zali, assieme ai direittori di OFIMA, Marold Hofstetter, e di AET, Roberto Pronini.
Il cantiere principale prevede di innalzare la diga di 15 metri, portandola dagli attuali 130 a 145 metri di altezza. Un intervento che consentirà di aumentare del 27% la capienza del lago, per un totale di 80 milioni di m3, corrispondenti ad un potenziale di 46 GWh di energia invernale supplementare.
L'attuale fase è quella di approfondimento di massima del progetto, seguiranno nel 2024-26 il progetto definitivo e la fase esecutiva (2027-30). L'investimento la diga e il rinnovo della centrale sarà di 120 milioni di franchi.
