Mexico awards construction of 750-MW La Yesca to ICA-led group

Mexico's Comision Federal de Electricidad (CFE) awarded a contract September 6 to a consortium led by Ingenieros Civiles Asociados (ICA) to build the 750-MW La Yesca hydroelectric project on the Santiago River.

The consortium, which presented the low bid of US$767.6 million, is led by ICA, Mexico's largest construction company, and includes Promotora e Inversora Adisa, La Peninsular Compania Constructora, and Constructora de Proyectos Hidroelectricos. (HNN 8/8/07)

Impulsora del Desarrollo y el Empleo en America Latina SA (IDEAL), the construction firm of Mexican billionaire Carlos Slim, bid second lowest at US$$811.2 million. Italy's Impregilo and consortium partners Techint, Prourbe del Bajio and Proyecto La Yesca offered the highest bid at US$$855.9 million.

CFE said the contract would be signed once the winning group delivered contract guarantees, said to be in 15 days.

"Work will start on September 27 and the finish date is July 11, 2012," said Jose Franco, CFE's deputy director of concessions.

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. Construction is to create 10,000 direct jobs.

ICA said it arranged financing for the project that will be structured by WestLB bank. The winning bidder has access to a development bank loan, to help cover investment in the estimated US$850 million project, under CFE's financed public works scheme.

In August, CFE said La Yesca was among its plans to increase its generating capacity by 27,000 MW to a total 69,000 MW by December 2016. (HNN 8/17/07)

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.
