The project, which should come on line in late 2013, will supply 13% of the mine’s power needs during daytime.
Collahuasi – a joint venture owned by UK-listed mining giants Xstrata and Anglo American, and a group of Japanese companies headed by Mitsui – has a peak demand of 190MW and operates the third-largest copper mine in the world.
The Chilean government-mandated power tender was originally for 12MW of capacity.
