La centrale idroelettrica di Robbia, in Valposchiavo, nei prossimi tre anni sarà completamente rifatta da Repower che si appresta ad affrontare il più grande intervento di rinnovo della sua storia. “Si tratta di uno dei progetti più importanti degli ultimi anni per Repower. L’idroelettrico è uno dei pilastri dell’approvvigionamento futuro”, sottolinea Samuel Bontadelli, responsabile gestione e servizi del colosso energetico.
L’investimento complessivo ammonta a circa 125 milioni di franchi e si stima che un terzo dei contratti potrebbe essere assegnato a imprese locali e cantonali.
I lavori preparatori in vista dell'apertura del cantiere principale, che si estenderà dalle opere di presa Salva e Braita fino ai canali di deflusso dell'impianto entrato in funzione nel 1910, inizieranno a fine giugno.
La conclusione degli interventi è prevista per il 2023. In seguito la centrale sarà in grado di produrre 120 gigawattora di elettricità all'anno (circa il 10% in più di oggi).
