Argentina: Growth in Electricity Transmission Networks 2022 [free access]

April 4, 2022

At the end of 2021, the country’s transmission network comprised about 35,727 km of transmission lines between the 132 kV AC and 500 kV voltage levels. Since 2016, transmission line length has witnessed a CAGR of 1.06 per cent.

 

Argentina’s transformation capacity has increased at a CAGR of 4.70 per cent since 2016 and stood at 51,938 MVA by the end of 2021. The number of substations increased to 158 in 2021 from 142 in 2016.
