Korea firm top bidder to study Ecuador’s 4,000-MW Zamora complex

Ecuadoran energy officials named Hyundai Engineering Co. Ltd. the highest ranking bidder of seven groups that submitted proposals to perform studies and detailed design of the 4,000-MW Zamora hydroelectric complex on Ecuador’s Zamora and Namangoza rivers.

The office of Ecuador President Rafael Correa previously said a proposal by Hyundai Engineering and SNC-Lavalin International of Canada was one of the seven bids received May 18, 2009. (HydroWorld 5/27/09) Ecuador’s Ministry of Electricity and Renewable Energy has called Zamora the largest and most important hydroelectric development in Ecuador.

Although officials have not said when the contract would be formally awarded, press reports of a July 6 meeting between Correa and a visiting South Korean business delegation quoted Ecuador officials saying Hyundai had won the competition. Reports from that delegation meeting also said Korea Electric Power Corp. is negotiating to develop the 100-MW Chontal and 280-MW Villadora hydroelectric projects, which are among 11 projects proposed for Ecuador’s Guayllabamba River complex.

Hyundai received 81.11 points in the Zamora competition, compared to 76.39 points for a runner-up consortium of Coyne et Bellier and Pietrangeli of France and Italy, Business News Americas reported. The contract has a reference price of US$29.5 million, with 720 days to complete the work.

The Ministry of Electricity and Renewable Energy called for technical and economic pre-feasibility and feasibility studies as well as detailed design of the Zamora complex (Lower Course), which could include 20 hydroelectric projects.

The ministry previously said the studies initially would focus on the most important project in the complex, the 1,200-MW San Juan Bosco hydro project. The consultant is to perform additional geological, geophysical, and geotechnical studies of the San Juan Bosco site.

Once the San Juan Bosco site is established, a pre-feasibility study is planned between it and the confluence of the Zamora and Namangoza rivers outlining technical and economic aspects of the functioning of the hydraulic system as a whole.
