Chile developer awards contracts to build, equip 136-MW Nuble hydropower project


Vial y Vives-DSD of Chile and Andritz Group of Austria have received contracts totaling US$257 million to build and equip the 136-MW Nuble hydroelectric project in southern Chile.

Electrica Puntilla S.A. and its subsidiary Hidronuble Spa awarded the contracts for development of the Nuble project, a run-of-river hydro plant on the Nuble River in Chile’s Region VIII.

Vial y Vives-DSD, a construction and engineering firm that is part of the Grana y Montero Group of Chile, is to construct the project intake, channel, powerhouse and hydraulic security works over 31 months.

Andritz is to supply, install and commission electro-mechanical and hydro-mechanical equipment including two turbines, gates, valves, transformers, and control and communications systems.

Electrica Puntilla said the Nuble project, a total investment of US$350 million, is to generate 620 GWh annually upon commissioning in 2017.

Twenty-six companies were pre-prequalified to bid on civil works and 12 on the equipment contract. Seven submitted civil works bids, while four submitted equipment bids.

Electrica Puntilla has six operating run-of-river hydro plants and seven in the development pipeline. President Pablo Jose Perez Cruz said the company expects to increase its current hydropower capacity of 74 MW installed and under construction to a total of 500 MW.

Chilean utility Compania General de Electricidad S.A. originally announced plans to develop Nuble. CGE’s development unit, CGE Generacion, signed an agreement in 2006 with MGM International of the United States for sale of carbon credits from Nuble to help finance its construction.
