Bolivia‚ÄďArgentina Interconnection Project [free access]

September 4, 2019

Developer: Bolivia’s Empresa Nacional de Electricidad (ENDE), and its Argentinian subsidiary, ENDE Transmisión Argentina SA (Etasa)


Project details and status: The interconnection project aims to facilitate the import of 120 MW of electricity from Bolivia’s Planta Termoeléctrica Del Sur located in Yaguacua, Department of Tarija, Gran Chaco province, to the Tartagal substation in the Salta province, Argentina. It entails the construction of a 110-km-long, 132 kV line from Yaguacua (Bolivia) to Tartagal (Argentina).


The project will be developed in two phases. The first phase will include the 46-km Bolivian portion of the project, and in the second phase, the project will be extended to Argentina. In Argentina, it includes the construction of a 64-km-long, 2x132 kV line from the Bolivia-Argentina border to the Tartagal substation. It also entails the extension of the 132/33/13.2 kV Tartagal substation of Transporte de Energía Eléctrica por Distribución Troncal del Noroeste Argentino SA (TRANSNOA SA) to accommodate the new 132 kV line. The Bolivian section of the project has already been completed. The project is being funded by Banco Central de Bolivia (BCB) or Central Bank of Bolivia.


The project is part of Plan de Desarrollo Económico y Social of 2016-2020 of Bolivia. In May 2016, Bolivia’s Ministry of Hydrocarbons and Energy, BCB and ENDE signed an agreement to extend BOB483.13 million for constructing Bolivia’s section of the interconnection.


In December 2018, ENDE Transmisión Argentina SA (Etasa) — an Argentinean subsidiary of ENDE — initiated construction works on the Argentinian section of the interconnection project. Etasa was established by ENDE in July 2018 to develop this section of the project.


As per an August 2019 update of Ministerio de Energía, Bolivia, the interconnection project will be completed by September 2019.
