St. Antönien avrà la sua centrale fotovoltaica sui suoi ripari contro le valanghe. Due anni dopo il fallimento di un progetto simile, l'assemblea comunale del villaggio grigionese ha infatti dato all'unanimità il via libera alla necessaria modifica della legge sulle costruzioni, come auspicato dalle autorità comunali.
Il progetto prevede l'installazione di 850 pannelli solari su un cavo teso tra i ripari contro le valanghe. Un sistema automatico permetterà di assicurare la massima esposizione al sole.
La capacità di produzione prevista è di 3 gigawatt all'anno, equivalenti al consumo di energia di 660 economie domestiche di quattro persone.
