Fernandez arrived on Thursday at the Tarija airport of Yacuiba and visited the Yaguacua town to hold a meeting with locals and to open the power transmission line.
The power supplier has a 120 km length (46.49 in Bolivia and 73.88 in Argentina) and connects the Yaguacua in Bolivia with the Tartagal substation in Argentina.
Such a project will allow to bring power from Bolivia to Argentina with an estimated power of 120 megawatts (MW).
The work required an investment of 364 million Bolivianos ($364 million). It had been completed in March 2018 in Bolivia, and in May 2019 on the Argentinean side.
Arce and Fernandez are currently leading the opening ceremony attended by ministers from both countries, lawmakers, leaders of social organizations and neighbors from the Chaco region of Yaguacua.
