Project Owner/s
Energía Provincial Sociedad del Estado.
Project Description
The 75 MW project involves the construction of an access road from the Los Caracoles power plant, the diversion channels for the San Juan river, a gravel concrete-faced dam with flood spillway and an open-air channel. Generation is pressure-driven and there is an external power plant.
The project is expected to generate more than 340 000 MWh/y of electricity.
Potential Job Creation
The project is expected to create more than 1 300 jobs.
Capital Expenditure
Not stated.
Planned Start/End Date
The project is expected to be completed in 2024.
Latest Developments
The diversion of the river for the construction of the dam was undertaken by building two parallel tunnels, lined with a reinforced concrete trunk section on the right bank of the river.
Both tunnels are 6 m in diameter and are 492 m long. One of the two tunnels will later function as a bottom outlet, so a sluice gate will be built inside it with an access tunnel leading to it.
Meanwhile, Energía Provincial Sociedad del Estado has received three bids to build the project from:
Panedile Argentina, SACDE, Sinohydro and Petersen, Thiele and Cruz for $544.36-million;
Techint and Tesur for $541.98-million; and China Gezhouba Group Company, Green, and Ivica and A. Dumandzic for $704.18-million.
