Argentina seeks bids to build 637-MW Chihuido 1 hydro project

Argentina’s federal planning ministry seeks bids to construct the 637-MW Chihuido 1 hydroelectric project on the Neuquen River in Argentina’s Neuquen Province. Bids are due April 23.

Chihuido 1 involves the construction of a 105-foot-tall dam across the Neuquen River and a hydro plant with four 159.25-MW Francis turbines. A reservoir is to be constructed for flood control, drinking water, irrigation and industrial water. A 130-kilometer transmission line is to connect the facility to the national grid.

Five groups submitted expressions of interest to build the then-478-MW project in 2009. However, Neuquen Province, which sponsored the initial solicitation, canceled it for failure to meet requirements to carry out the work.

Argentina’s Ministerio de Planification Federal, Inversion Publicas y Servicios now seeks bids to construct the project over four years at an estimated cost of US$2.1 billion. Ministry officials previously promoted the project in a development road show to Russia, China and Brazil.

Bids are due April 23. Tender documents and other information may be obtained from the ministry Internet site under
