Project Details


The Yacyretá-Villa Hayes transmission line project aims to improve Paraguay's power supply by significantly strengthening its electricity transmission infrastructure. The proposed interconnection would extend from the Yacyretá hydroelectric dam to the Villa Hayes substation. The transmission line is expected to stretch 363km. Work is to be divided into two phases. The first stretch will run from the Yacretá hydroelectric plant to Paraguarí department, passing through the Ayolas substation (16km north of the plant). The second stretch will connect Paraguarí department with Villa Hayes, which lies outside capital Asunción.
