Costa Rica seeks supporting studies for 630-MW El Diquis

The Inter-American Development Bank (IADB) seeks expressions of interest from consultants to perform two supporting studies for development of the 630-MW El Diquis hydroelectric project on Costa Rica’s General Superior River. Responses to two separate solicitations are due October 31.

Formerly called the Boruca-Veraguas project, El Diquis has been studied by government utility Instituto Costarricense de Electricidad (ICE) for many years. Boruca-Veraguas was chosen as an alternative to a 709-MW Boruca-Cajon proposal because it is expected to have fewer social and environmental effects.

In addition to IADB assistance, the U.S. Trade and Development Agency is funding geotechnical and financial studies of the project. (HNN 9/11/07) ICE said the project is located in one of the less-developed parts of the nation and is to improve socio-economic conditions while complementing regional electricity system integration.

In one solicitation, IADB seeks consultants to develop an environmental impact study for submission to environmental regulator Secretaria Tecnica Nacional Ambiental. The consultant is to identify positive and negative effects of the project and formulate a risk management plan, emergency action plan, and environmental management plan.

In the other solicitation, IADB seeks consultants to determine the regional-local institutional potential of the El Diquis project area and to initiate a plan for inter-institutional coordination and cooperation.

Expressions of interest and qualifications for both solicitations are due by 5 p.m. October 31.
