SunEdison has signed an agreement with one of the world’s largest copper mining companies, Antofagasta Minerals S.A., to install a solar power system to help power some of the Los Pelambres mine.

A 69.5MW system is to be installed and supply some of the electricity demand of the mine. This mine also uses wind energy for some of its electricity and plans to install hydro power as well. By 2015 they expect that 30% of their electricity demand will come from renewable sources.

The 69.5MW Javiera solar photovoltaic project is under construction and will be commissioned and connected to the grid early next year under a 20 year contract.

“This landmark project reinforces SunEdison’s ability to offer competitive, innovative and sustainable energy solutions to its customers and reaffirms SunEdison’s leading role in Latin America,” said Jose Perez, president of SunEdison for Europe, the Middle East, Africa and Latin America.

Antofagasta is looking to keep adding renewables as they reported a 5% increase in CO2 emissions between 2012 and 2013 and had total emissions of 2.2million tonnes of CO2 equivalent in 2013.
