ICA-led consortium is low bidder to build Mexico’s 750-MW La Yesca

A consortium led by Mexico’s Ingenieros Civiles Asociados (ICA) is the low bidder to build the 750-MW La Yesca hydroelectric project on the Santiago River.

Mexico’s Comision Federal de Electricidad (CFE) said August 7 that three groups bid to build La Yesca, which would be one of the world’s tallest dams. Bids were due July 31. (HNN 2/28/07)

CFE said the winning bid will be announced September 6.

The lowest bid, at US$768 million, was presented by the consortium including ICA, Mexico’s largest construction company. Other consortium partners are Promotora e Inversora Adisa, La Peninsular Compania Constructora, and Constructora de Proyectos Hidroelectricos.

IDEAL, the construction firm of Mexican billionaire Carlos Slim, bid second lowest at US$808 million.

Italy’s Impregilo and consortium partners Techint, Prourbe del Bajio and Proyecto La Yesca offered the highest bid at US$856 million.

In November 2006, CFE rejected bids by consortia led by ICA and by China’s Sinohydro Corp. because they exceeded the ceiling price set by the government. Another bid, by a group led by Impregilo, had failed to achieve technical requirements.

To be located at Hostotipaquillo in Jalisco State, La Yesca is to include a 220-meter-tall concrete-faced rockfill dam, a reservoir of 2.39 billion cubic meters, and an underground powerhouse containing two 375-MW turbine-generators. Bidding included civil, electro-mechanical, and associated work.

The winning bidder is to have access to a development bank loan, to help cover investment in the estimated US$850 million project, under CFE’s financed public works scheme. CFE plans on first unit completion in February 2011, followed by second unit completion in May 2011, and completion of the project in June 2011.

In July, the Inter-American Development Bank (IADB) approved US$200,000 for a pilot project to manage environmental and social aspects of La Yesca. (HNN 7/31/07)
