Uruguay: Growth in electricity transmission network and capacity [free access]

Uruguay’s transmission network is operated by Administración Nacional de Usinas y Trasmisiones Eléctricas (UTE). As of 2019, the country’s transmission network comprised about 5,853 km of line length at the 150 kV and above voltage levels. Of the total line length, the majority, or about 77 per cent, was at 150 kV, followed by 23 per cent at 500 kV and the rest at 230 kV. Since 2015, Uruguay’s transmission line network has grown at a CAGR of close to 4.5 per cent, with net additions of over 951 km.

The transformer capacity of Uruguay stood at 10,195 MVA as of 2019. 66 per cent of the transformer additions took place at 150 kV during 2015-19. Further, the country has added 15 substations in the past five years to reach 92 substations by 2019.
