Int​ernational interconnections 

We operate four medium and large interconnections with other South American countries:
 

  • With Paraguay, through four 500 kV transmission lines, which connect the Itaipu binational hydroelectric power plant to the Right Bank Substation (Paraguay) and the Foz do Iguaçu Substation (Brazil). Power produced by the Paraguayan sector of the plant can be supplied to Brazil from the Foz substation to the Ibiúna (SP) substation through a 6,300 MW direct current transmission system;

  • With Uruguay, through the Rivera frequency converter station (Uruguay), with a capacity of 70 MW, and a 230 kV transmission line, which connects the converter to the Livramento substation (Brazil);

  • With Argentina, through the 50 MW capacity Uruguaiana (Brazil) frequency converter station, and a 132 kV transmission line, which connects the converter to Paso de los Libres (Argentina);

  • With Venezuela, through a 230 kV transmission line with a capacity of 200 MW, which connects the city of Boa Vista (Brazil) to the city of Santa Elena (Venezuela).

  • With Uruguay, through the 500 MW capacity Melo frequency converter, through a 500 kV transmission line, which connects the converter to the Candiota 230/525 kV substation.
