Ecuador developer seeks design bids for 312.6-MW Sopladora

Hydro generator Hidropaute S.A seeks bids for detailed design of the 312.6-MW Sopladora hydroelectric project, to be built on Ecuador’s Paute River. Bids are due December 14.

Power regulator Consejo Nacional de Electrificacion (Conelec) granted a concession certificate to Hidropaute in March, giving the generator the exclusive right for construction and operation of the hydro project. Hidropaute currently is soliciting an environmental impact statement for the project. (HNN 3/13/07)

The project is to have no dam, but is to utilize water discharged by the 1,075-MW Paute project, which Hidropaute operates. The ministry said, together with the 162.6-MW Mazar project that Hidropaute is developing, the projects will optimize use of the Paute River’s hydro potential. (HNN 1/18/07)

Hidropaute said it seeks a consultant to validate existing studies and to study optimization of the project in relation to Paute and Mazar. Work then includes definitive design of civil works and general designs for use by a manufacturer to design hydro-mechanical and electro-mechanical equipment.

The energy and mines ministry has previously said completion of definitive design could result in the project’s installed capacity being increased to 400 MW. The ministry said Sopladora is to be complete in 2011, generating power for 3 cents/kWh.

In August, the technical committee of Ecuador’s energy and hydrocarbon investment fund approved feasibility studies of Sopladora and Mazar. (HNN 8/29/07) The agency agreed to provide 71 percent, US$228.4 million, of Sopladora’s total cost of US$322 million.

Bid documents for the definitive design contract may be obtained from the address below until November 14 for US$2,000 by cash or certified check to Hidropaute S.A. Two-part bids, technical and economic, must be hand-delivered by 5:50 p.m. December 14.
