Endesa Chile names Voith to equip 150-MW Los Condores hydro project

Chile

Utility Endesa Chile has awarded a contract to Voith Hydro to supply electro-mechanical equipment to the 150-MW Los Condores hydroelectric project being built on Laguna del Maule reservoir in Chile’s Region VII.

Endesa Chile signed a contract with Voith in which the equipment supplier is to supply, install and commission two Pelton turbine-generators totaling 150 MW and related equipment and is to provide project management for Los Condores. The project is to have an estimated plant factor of 48 percent and an average annual generation of 642 GWh. The key electro-mechanical components are to be manufactured at Voith Hydro in Sao Paulo, Brazil.

The board of Endesa Chile agreed in March to invest US$661.5 million to construct the project. It originally invested US$273 million in the project in 2008.

The board also awarded in March a civil works construction contract to Consorcio Ferrovial Agroman, which already has begun construction of work site facilities and excavation for tunnel portals, a cable connection yard and underground powerhouse. Civil works — including construction of the intake, 12-kilometer tunnel, headrace, powerhouse and discharge channel — are expected to take about four years, with Los Condores being put into operation in the fourth quarter of 2018.

Endesa submitted a new environmental impact assessment to Region VII environmental authorities in 2011, reducing the size and surface area of the dam and moving the powerhouse completely underground.

Endesa said the changes reduce the surface area to be used with less environmental impact on scenery, soil, vegetation and fauna in the area. The utility also reached agreement with area irrigators to optimize use of water from Laguna del Maule and to cooperate with the Maule River supervisory board to address water usage during drought.
