Bolivia utility Empresa Nacional de Electricidad (ENDE) has awarded contracts to supply a penstock and steel surge shaft liner, and to supervise construction of the 80-MW Misicuni multi-purpose hydroelectric project on Bolivia’s Misicuni River.
The multi-purpose project, already under way, includes Misicuni Dam and a diversion tunnel, which is to deliver water from the Misicuni River through mountains to the Cochabamba Valley for Cochabamba municipal water supply and irrigation of 15,000 acres. ENDE took bids in February to equip the hydro plant.
ENDE awarded a contract to Carlos Caballero S.R.L. for design, manufacture, transport, assembly, testing, and commissioning of the hydro project penstock and steel liner of the surge shaft. Carlos Caballero submitted a bid of US$27.2 million for the work, which is to require 29 months.
The only other bidder, Sinohydro Group Ltd. at a total US$39.5 million, was rejected due to incomplete technical information of its proposal.
ENDE awarded a US$4.38 million contract to Dessau International Inc. to supervise construction of the Misicuni hydroelectric plant, including design of civil works and coordination of contracts for construction and supply of equipment. Dessau submitted a bid of US$3.81 million for the work, which is to require 33 months.
Dessau was selected over bids of Gas Natural Fenosa Engineering SLU at US$3.89 million and Consorcio Fichtner-Stucky-Gregory Morris at US$9.2 million.
