Construction on Chile's largest hydroelectric initiative, the 2,750-MW HidroAysén project, is awaiting final approval by the country's environmental agency, which is expected to respond by next month.
HidroAysén—a joint venture between Chilean power utilities Empresa Nacional de Electricidad SA and Colbun SA—submitted its environmental impact assessment on April 15. A decision by the Chilean government on the environmental license for the project is expected in May.
