Rame's sub-contractor CGE Distribucion will build and own the export line, with operations at all four projects, totalling 118MW, due to commence by end of next year.

"The granting of the environmental permit for the export power line at Punta Chome brings us closer to our stated targets of having in excess of 100MW of power generating capacity installed and in operation in Chile by the end of 2015 and 300MW within three years," said Pieter D'haen, Rame's COO.
