Mexico restarts bidding to build 750-MW La Yesca

Mexico’s Comision Federal de Electricidad (CFE) issued a solicitation February 27, restarting bidding for construction of the 750-MW La Yesca hydroelectric project on the Santiago River. A site visit is set March 6, with bids due July 31.

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 is to include civil, electro-mechanical, and associated work. (HNN 1/26/07)

Late last year, CFE rejected bids by a consortia led by Mexico’s Ingenieros Civiles Asociados and by China’s Sinohydro Corp. because they exceeded the ceiling price set by the government. Another bid, by a group led by Italy’s Impregilo, failed to achieve technical requirements, the utility said.

CFE said modifications in the bidding requirements were made to encourage greater participation by Mexican companies.

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.

Bid documents may be examined on CFE’s Internet site,
