Rehab study sought for two 50-MW Nicaragua hydros

The Central American Bank for Economic Integration (CABEI) seeks bids for a feasibility study of rehabilitating two 50-MW hydroelectric projects in Nicaragua. Bids are due June 28.

On behalf of Nicaraguan utility Empresa Nicaraguense de Electricidad (Enel), CABEI seeks a consultant to determine improvements necessary to refurbish the 50-MW Centroamerica and 50-MW Santa Barbara hydroelectric projects. An Enel subsidiary, Generadora Hidroelectrica S.A. (Hidrogesa), operates the plants, which began operation in 1965 and 1971.
