BOLIVIA – ENDE, SAN JOSÉ HYDROELECTRIC POWER PLANT.

Turnkey project for two 124 MW – 230 kV GIS substations and high voltage line.

Project:

As part of the Bolivian government’s policy to diversify the country’s power grid and export its excess electric energy, the state-owned power company, Ende —with CAF’s [Development Bank of Latin America] fundings— has approved the San José hydroelectric project.

The purpose of this project is to increase energy production using the water potential of the upper Chapare river basin, the Málaga and Santa Isabel rivers, and the waters of the Corani reservoir, by means of turbines placed at the Corani and Santa Isabel hydroelectric plants. The project includes the construction of a dam, the Locotal regulating reservoir, the adduction tunnels, the penstock and the powerhouse. It also includes the construction of San Jose I and San Jose II hydroelectric power stations, meant to generate 55 MW and 69 MW, respectively, with a total investment of US$252 million.

In 2015, ENDE called for bids on the last contract, corresponding to works including the design, supply and erection of substations associated to powerhouses 1 and 2, a 7 km connection between the substations, and a connection from powerhouse 1 to the Miguelito substation.

Our Work:

After a long and demanding selection process involving topmost tier international companies, Ingener was awarded a major turnkey contract for the completion of these works. The main equipment included in the project is the power transformers – two units in each power plant for each power generation unit – and the 230 kV SF6 GIS for transfer to the transmission line, including the outlet gantry. Our scope of supply also comprises the protection and control equipment and the associated auxiliary services, and the transmission line.
