Ecuador seeks studies for hydro projects in Guayllabamba Basin

Ecuador's investment institute invites expressions of interest from consultants to study and design hydroelectric projects in Ecuador's upper Guayllabamba River Basin. Responses are due July 6.

Ecuador and Pichincha Province signed agreements in 2008 to develop 11 hydroelectric projects totaling 1,670 MW in the Guayllabamba River hydroelectric system. Projects then included Chespi, Villadora, Chontal, Calderon, Cubi, Palma Real, San Pedro, Chirapi, Mandarayacu Grande, Tortuga, and Llurimaguas. Since then, officials of South Korea and Iran have expressed interest in developing projects in the basin.

Ecuador's Instituto Nacional de Preinversion (INP) seeks consultants to perform pre-feasibility and feasibility studies and final design of projects. Studies are to establish water use for optimal hydroelectric potential of the upper basin. INP said projects are expected to provide about 300 MW to the national grid.

The consultant is to review existing information on the projects developed by Ecuador's former electrification agency, Inecel, and is to implement appropriate activities of each study phase. The work is to take about 20 months with a budget of US$11.6 million.

Expressions of interest are to include information requested on a form available at the INP Internet site,, under Expresiones de Interes. INP plans to invite a short-list of bidders to submit proposals.

Responses are due by mail or e-mail by 5:30 p.m. July 6. For information, contact Direccion de Gestion Tecnica, Av. Republica de El Salvador No. 1082, Edificio Mansion Blanca, Torres Londres, Piso 4, CP 170102 Quito, Ecuador; (593) 22469849; Fax: (593) 22244532; E-mail:; Internet:
