Mexico seeks comments on tender to build 244-MW Chicoasen 2 hydro project

Mexican utility Comision Federal de Electricidad (CFE) seeks comments from prospective bidders on a proposed solicitation to construct the 244-MW Chicoasen 2 hydroelectric project on Mexico’s Grijalva River. Responses are due November 8.

Chicoasen 2 would be built in the municipality of Chicoasen in Chiapas State near the 2,430-MW Chicoasen (Manuel Moreno Torres) hydroelectric project built in 1980. The Grijalva River hydroelectric complex also includes 420-MW Penitas (Angel Albino Corzo), 900-MW La Angostura (Belisario Dominguez), and 1,080-MW Malpaso (Nezahualcoyotl) projects. CFE named Mexico Constructora Industrial S.A. de C.V. in 2009 to build two diversion tunnels to bypass a mudslide that blocked the Grijalva River among the dams of the hydroelectric system.

CFE plans to issue a solicitation in December for civil works, electro-mechanical equipment, and associated works for Chicoasen 2, which features a diversion structure and channel, cofferdams, retaining wall, powerhouse equipped with three 82.63-MW bulb turbines, downstream spillway, and substation.

Draft tender documents may be obtained from the CFE Internet site under

CFE seeks comments on the documents by November 8. A site visit is scheduled December 9, followed by bid meetings December 16-23. Bids are expected to be due April 22, 2014.
