Costa Rica seeks transformers to refurbish 120-MW Rio Macho hydro project

Costa Rica’s electric utility seeks bids to supply transformers to help refurbish the 120-MW Rio Macho hydroelectric project on the Macho River. Bids are due April 9.

With funds from the Inter-American Development Bank, Instituto Costarricense de Electricidad awarded a contract in 2011 to Andritz Hydro for electro-mechanical equipment to modernize Units 1 and 2, which were built in 1959 and 1963, and for plant-wide control and protective systems. The work is expected to increase each unit’s capacity by 2.5 MW.

The utility now seeks bids to supply transformers in a contract valued at US$3.96 million.

Solicitation documents in Spanish may be obtained from the address below. Bids are due by 9 a.m. April 9.
