Spanish firm wins contract to build Bolivia’s 200-MW Miguillas hydro project

Bolivia utility Empresa Nacional de Electricidad (ENDE) has awarded a contract to Corsan Corviam of Spain to construct the two-plant, 200-MW Miguillas hydroelectric project in Bolivia’s La Paz Department.

ENDE took expressions of interest for the work in August. Banco Central de Bolivia lent US$450 million to ENDE and Bolivia’s Ministerio Hidrocarburos y Energia in June for construction of Miguillas, which includes two hydro plants, 116-MW Palillada and 84-MW Umapalca.

In an October 2 ceremony attended by Bolivia President Evo Morales, officials of ENDE and Corsan Corviam signed contracts for construction of the hydro plants and a transmission line.

Under a US$397.9 million contract, Corsan Corviam is to construct the Miguillas project on an engineering-procurement-construction basis in Bolivia’s Inquisivi Province. Work is to include design, supply and construction of intakes, dams, regulation reservoirs, access roads, conduits, pipes, tunnels, valve chambers, surge tanks, penstocks, two powerhouses with a total of six horizontal Pelton turbine-generators, two substations, hydro-mechanical equipment, controls and protection.

Under a second contract worth US$27 million, Corsan Corviam is to construct a transmission line connecting Miguillas to the national grid.

The work is expected to require 1,440 days.

ENDE awarded a contract in June to China’s Sinohydro Corp. for civil construction of the two-plant, 124-MW San Jose hydroelectric project. Bolivia’s special purpose company Empresa Misicuni also took bids in June to resume construction of the dam of the 80-MW Misicuni multipurpose hydro project.
