Argentina province seeks studies of 90-MW Portezuelo del Viento

Argentina’s Mendoza Province seeks bids from consultants for studies and preparatory work to develop the 90-MW Portezuelo del Viento hydroelectric project on Argentina’s Rio Grande. Bids are due December 15.

The province seeks a consultant for economic and technical feasibility studies, basic studies, project execution, and development of solicitation documents for construction. The budget for the contract is 11.49 million pesos (US$3.73 million).

Deputy Infrastructure Secretary Carlos Santilli previously said the province is still defining project details, which include two alternatives. (HNN 9/5/06) A 90-MW alternative would build the powerhouse at the dam toe to generate 650 gigawatt-hours per year. A 120-MW alternative would build the plant below the dam to generate 990 GWh per year.

Under the 90-MW scenario, Portezuelo del Viento would include a 151-meter-tall, 510-meter-long concrete-faced rockfill dam and a powerhouse containing three 30-MW Francis turbine-generators.

In June, a basin agency, Comite Interjurisdiccional del Rio Colorado, approved plans for Mendoza’s Ministerio de Ambiente y Obras Publicas to draft tender documents for design of the estimated 1 billion peso (US$324 million) project.

Santilli said construction would begin by the end of 2007 at the earliest and would require up to six years.

Bidding documents may be obtained for 15,000 pesos (US$4,870) from Direccion de Administracion de Contratos y Obras Publicas, 8vo. Piso, Casa de Gobierno Centro Civico, Mendoza. Documents also can be obtained from the province Internet site,
