Argentina: Growth in electricity transmission network [free access]

September 13, 2018

As of end-2017, Argentina’s high voltage (HV) transmission network spanned over 34,048 km, of which 50 per cent was operational at the 132/138 kV voltage level. Since 2013, the country’s transmission network has increased at a CAGR of 1.7 per cent.

 

Argentina’s transmission grid is divided into two systems; the first is the HV system, which includes facilities of voltages of 220 kV and above and transmits electricity between regions. The second comprises the trunk distribution lines, which are between 132 kV and 400 kV and connect generators, distributors and large users within the same region.

 

Argentina’s electricity grid is connected to the transmission systems of Brazil, Uruguay and Paraguay.

Argentina’s transmission system is completely in the hands of private companies. The majority of the line length is owned by the Compañía de Transporte de Energía Eléctrica en Alta Tensión Transener S.A. (Transener), which holds a concession for the ownership, operation and maintenance of the transmission network at the 500 kV and 220 kV levels.
