Latin bank extends calls for modernization, expansion of 1,890-MW Salto Grande hydro project

Salto Grande Hydropower Project

The Inter-American Development Bank (IADB) has extended the deadline for expressions of interest from consultants to advance modernization and expansion of the bi-national 1,890-MW Salto Grande hydroelectric project on the border of Argentina and Uruguay. Responses to three solicitations now are due February 7.

IADB previously called for responses by January 24. The bank provided financing in July to allow the project's bi-national operating entity, Comision Tecnica Mixta Salto Grande (CTM), to study areas of potential improvements and modernization of Salto Grande.

Argentina has called Salto Grande its second most important hydroelectric project, after 3,200-MW Yacyreta on the Parana River. Salto Grande is located on the Uruguay River, which is being eyed for other hydropower development by Argentina and Brazil, the other neighbor on the river.

CTM -- a public bi-national entity of Uruguay and Argentina – plans to use IADB's US$1.36 million in financing to explore options in additional generating capacity and efficiency upgrades. Operating since 1989, most of Salto Grande's equipment is reaching the end of its life cycle, IADB said.

In the first of three solicitations, RG-T2256-SN1, IADB invites expressions of interest to prepare a comprehensive diagnosis of the Salto Grande complex including a study of potential to increase generating capacity and design of a strategic action plan. Consultants must have extensive experience in studies, design, and detailed engineering of civil and electro-mechanical works of large hydroelectric plants, substations, and transmission lines.

In a second solicitation, RG-T2256-SN2, IADB invites expressions of interest to prepare hydrological studies of the Salto Grande complex including detailed analysis of existing studies, historical information, and evaluation of impacts on hydrological behavior of the basin. The consultant is to make recommendations to ensure extended life of the project for the next 30 years.

In a third solicitation, RG-T2256-SN3, IADB invites expressions of interest to identify areas in which project environmental management can be updated considering new technologies and practices in the field, and to develop an environmental management plan for the medium and long term. Consultants are to have experience in environmental audit and diagnosis of large infrastructure, especially hydropower projects.

Expressions of interest for all three solicitations now are due by 5 p.m., U.S. Eastern time, February 7 via the IADB e-Sourcing Internet site at For procurement information, see the IADB Internet site under,1303.html?id=RG-T2256#doc.
