With the start-up of the transmission projects described, the achievements and benefits that have materialized, among others, are the following:
- The transmission system of the National Interconnected System (SIN) has been strengthened, with the execution of projects in the departments of La Paz, Santa Cruz, Tarija, Chuquisaca, Potosí and Cochabamba.
- The connection to the SIN of new generation plants, thus making it possible to dispose of the generated energy, making it possible for distributors to meet the growing demand in the regions.
- An underground high voltage line was installed to supply electrical energy to the Potassium Salts and Lithium Carbonate Plants, for the industrialization of the evaporite resources of the Uyuni salt flat, located in the Salar de Uyuni itself, building the underground line in highly corrosive soil.
- The first section of the 132 kV transmission line was completed for the international interconnection with Argentina, located in Bolivian territory, which will allow the sale of electricity to the neighboring country and will generate income for Bolivia.
- The country’s first two extra-high voltage lines, at 500 kV, are being built in the central section of the SIN, which will allow the transmission of power from current generation plants and those planned for the future, located in the central and eastern areas. , to supply the national demand, as well as the export market.
