Centrales Hidroelectricas de Aysen S.A. (HidroAysen) has awarded a contract to a Chilean-Scandinavian consortium to develop an environmental impact statement for Chile’s 2,500-MW Aysen hydroelectric complex.
HidroAysen, a joint venture of utilities Endesa Chile and Colbun S.A., said the consortium of SWECO, of Sweden and Norway, and POCH Ambiental y EPS, of Chile, was selected from among nine bidders competing for the EIS contract. The work is to be completed in 2007 in the Aysen region of Chile’s Region X.
Chile’s utility regulator recently granted a concession to HidroAysen, which is to be responsible for study, development, financing, construction, and operation of the US$4 billion hydropower and transmission line project. (HNN 12/5/06)
HidroAysen plans to develop the 680-MW Baker 1 and 360-MW Baker 2 plants on the Baker River and the 450-MW Pascua 1 and 940-MW Pascua 2 plants on the Pascua River, called, collectively with a fifth, 70-MW plant, the Aysen project.
In July, an Endesa official said the utility planned to complete studies and engineering in June 2008, after which it would issue a construction tender for the first plant, Baker 1.
