San José - A Pelton project in Bolivia

In February 2015, the EPC contractor POWERCHINA Kunming Engineering Corporation Limited awarded a contract to ANDRITZ HYDRO China for the supply, installation supervision, and commissioning supervision of four Pelton turbines at San José hydroelectric complex in Bolivia

Owned by Bolivia’s state power utility Empresa Nacional de Electricidad (ENDE), the hydroelectric complex is located in the Chapare Province in the center of Bolivia and is part of the expansion plan for the Corani Basin hydroelectric projects. It consists of two powerhouses, San José 1 (two 28 MW Pelton units) and San José 2 (two 35 MW Pelton units). Both run-of-river power plants are designed to use the river basin of the upper Chapare River, Malaga and Santa Isabel rivers as well as the Corani reservoir attached to the existing Santa Isabel hydropower plant.

ANDRITZ HYDRO will supply design, manufacturing, delivery, installation supervision, and commissioning supervision of four Pelton turbines for the HPP San José project. All works will be executed by ANDRITZ HYDRO China in collaboration with ANDRITZ HYDRO Italy.

The HPPs San José 1 and 2 are expected to provide 754 GWh of electrical energy per year, destined for domestic use.

The project is scheduled to be put into operation by end of 2017.
