The idea of building an iron and steel plant strategically near to raw material was that of the Belgian entrepreneur Charles Van der Straten Pontoz who founded the company “Miniere di Cogne” at the beginning of 20th Century. However, the development of the electricity-powered iron and steel project in Aosta Valley was undertaken by Pio Perrone. Skilled Italian and Swedish technicians supported the project. He thus created, in those difficult years of the first world war, a unique electric steel plant fed by Cognes magnetite and by the electricity produced in the Aymavilles, Chavonne and Champagne power stations.
