Compared to a coal-fired power plant, the electricity produced annually by the El Arrayán wind project will offset more than 300,000 metric tons of carbon dioxide, the equivalent of the annual carbon footprint of more than 70,000 Chileans. In addition, the project will conserve enough water to supply more than 11,000 Chileans.

The 115-megawatt Parque Eólico El Arrayán will become Chile's largest wind energy facility when it reaches commercial operation in early 2014. The project is located in Chile's 4th Region, approximately 400 km north of Santiago, and will make use of strong coastal winds to deliver renewable energy onto the central SIC power grid.

The project will utilize 50 Siemens 2.3 MW wind turbines and is being constructed by Skanska Chile. The project will create significant job opportunities during construction and operation and represents an important investment in energy infrastructure to meet the needs of the growing Chilean economy. El Arrayán will provide the largest contribution to date in meeting Chile's goal of 20% non-conventional renewable energy.

El Arrayán has entered into a 20-year power offtake agreement with Minera Los Pelambres, a mining company controlled by Antofagasta Minerals S.A., for the sale of energy and environmental attributes produced at the facility.
